With so many hole saw kits to choose from, narrowing them down to the best options was challenging. However, after a lot of research, we have reviewed seven of the best hole saw kits that are currently available, chosen for their teeth per inch and how they are arranged, and the materials they are suitable for cutting.

1. Milwaukee 49-22-4285 All Purpose Hole Saw Kit

Best All-Purpose Hole Saw Kit

Milwaukee is one of the most respected names in tools in the United States, and this hole saw kit lives up to that reputation. It has bi-metal teeth with a positive rake for faster, more efficient cutting.

This is a 28-piece kit, so it should have the right size for the majority of holes you will need to drill. This Milwaukee set contains hole saws that range from a small size of 0.75 inches up to the largest size of 4.75 inches. It also includes three arbors and three drill bits.

The blades have been ice treated to make them 50% more durable, and the gullets are deeper to scoop out the debris more effectively. The only downside of this kit is its price, which might be too much for beginner DIYers. For professionals, however, it will make an excellent addition to your tool collection.

Pros

  • 28-piece kit
  • Ice hardened for durability
  • Bi-metal teeth
  • Positive rake

Cons

  • Might be too expensive

2. Greenlee Carbide Cutter 6-Piece Hole Saw Kit

Best Hole Saw Kit for Metal

If you want a hole saw set that is suitable for cutting through metal, this kit is a great option. It contains six pieces, including five cutter heads ranging in size from 0.87 inches to 2 inches. There is also a spring-loaded pilot drill to make it easier to remove the slug.

This kit is made of steel with carbide-tipped teeth for optimal performance, with a cobalt steel pilot drill. It also includes a quick-change auger for when you need to swap to a differently-sized cutter head.

The price is the only reason that you might want to look elsewhere, especially considering that this kit only contains six pieces. However, it is a specialist set that is ideal for drilling holes in metal, so it might be worth the extra cost.

Pros

  • Carbide-tipped
  • Cobalt steel pilot drill
  • 6-piece set
  • Perfect for drilling through metal

Cons

  • Expensive
  • Limited size range

3. 3 Otters Hole Saw Set

Best Hole Saw Kit for Glass

The 3 Otters set is nickel-plated. These blades will cut through tiles, glass, ceramics, jars, and even granite. If you are tackling delicate tasks such as fitting work surfaces in the kitchen or bathroom, these hole cutters will be ideal.

This is a 15-piece set, with sizes ranging from 0.24 inches to 2 inches. The drill bits are made of carbon steel, which is then coated in nickel to preserve the material and increase its lifespan.

The diamond coating cuts differently from standard hole saws. Diamond grit scrapes tiny particles from the surface of the material, resulting in a smoother, more precise finish. This gradual cutting process will allow you to cut holes in even the most fragile materials.

Pros

  • High quality
  • 15-piece set
  • Can cut through glass safely

5. Freud DHS17SPL Bi-Metal Plumbing Set

Best Hole Saw Kit for Plumbers

6. Sungator 5-Piece Hole Saw Set

Best Hole Saw Kit for Fiberglass

If you are cutting through fiberglass, you need a hole saw with precision teeth to make a neat cut. You won’t need the most robust hole saw, as fiberglass is a relatively soft material.

This Sungator hole saw kit contains five pieces, with sizes ranging from 1.25 inches to 2.13 inches. It has a maximum cutting depth of one inch. The set is made of heat-treated carbon steel, so it might not be the toughest material but should still get the job done.

In addition to receiving numerous positive user reviews, this set is also very affordable, costing about a tenth of some of the more expensive kits we have looked at. If you are concerned that carbon steel may be too soft for some cutting tasks, at least these blades will be much cheaper to replace than most of their rivals.

Pros

  • Very reasonable price
  • Precision teeth
  • Carbon steel
  • 5-piece set

Cons

  • Only suitable for softer materials

What Are Hole Saw Kits?

A hole saw kit has a cylindrical blade that can cut perfectly round holes in various materials. Plumbers, electricians, and other professional contractors often use them as they are ideal for making holes to accommodate cables and pipework, and for general tasks such as drilling through walls, floors, and ceilings.

They allow the user to create holes with a much wider diameter than a standard drill bit, but they are still attached to a handheld drill. They also usually have a pilot drill in the center to prevent the hole saw from moving side to side while cutting.

What to Look for in a Hole Saw Kit

There are numerous hole saw kits available, so it is very helpful to know what you are looking for. Let’s take a quick look at some of the most important things to keep in mind when choosing a hole saw kit.

Materials

It is essential to think about materials, both the material the saw blade is made of and the material you will be cutting into.

If you are drilling wood, fiberglass, or plastics, a steel hole saw should be sufficient. This doesn’t mean cobalt hole saws are ineffective at cutting these materials, but you would be wasting money buying a hole saw designed for tougher materials.

Cobalt hole saws are tough enough for dense materials such as steel and aluminum. This added strength is thanks to the cobalt-steel alloy and its ability to withstand heat. Heat is one of the main reasons why drills and saws dull over time, so a heat-resistant material will be far more durable.

Carbide-tipped hole saws stay sharp for the longest time, while tungsten or titanium-tipped hole saws make the best all-around hole cutters. These are the most often used materials in high-quality hole saw kits.

Sizes

If you usually only drill holes of the same size, such as for fitting ceiling lights, you are unlikely to need a large selection of hole saws. This also means you could spend your money on one hole cutter of very high quality, rather than getting a large set of lower quality.

However, if you are cutting many different size holes, such as for plumbing work, it is worth investing in a hole saw kit. It will give you much greater freedom and save you a lot of time while fitting pipework of various sizes.

Drill Bit

Drill bits are available in various shapes and sizes. The longer the bit, the more effective it will be at anchoring the hole saw to the material. Shorter drill bits provide more stability and rigidity, which means they are better suited to harder materials.

Remember

You also need to consider the Arbor shank size. They typically come in three sizes: 0.25-inch, 0.35-inch, and 0.45-inch. Make sure you choose a shank that is smaller than your chuck size.

Teeth

The cutting power of these hole saws is dictated by the number of teeth they have, the gullet depth, and how the teeth are angled. The rake angle describes the angle of the cutting surface relative to the material.

A positive rake slopes away from the cutting edge on the inner side, while negative rakes slope away from the outer side.

Deeper gullets remove material more efficiently and scoop debris away from the stock, while the number of teeth will influence how neat the sides of the hole are. Having more teeth should create a neater hole, including in harder materials, but it also means you will cut more slowly.

Hole saws with fewer teeth are better suited to lumber and other materials that require a less precise edge as they will rip rather than make a smooth cut.

Warranty

The prices and durability of hole saw kits vary greatly, which is reflected in the many different warranties you will see. Well-known brands such as DeWALT and Milwaukee offer a 3-year warranty and a lifetime guarantee, respectively.

In comparison, some cheaper brands offer a 12-month warranty at most. Warranties are usually a reliable indicator of how long manufacturers expect their products to last, so the longer the better.

Who Makes the Best Hole Saw Kits?

You will probably recognize most of these brand names, even if you aren’t a passionate DIYer or a professional.

DeWALT

DeWALT is a household name in DIY in America and around the world, thanks to the high quality of its products. The company was started in 1923 by Raymond E. DeWalt when he invented the first radial arm saw to increase productivity at a sawmill (1).

It has since grown into one of the most internationally recognized tool brands in the world.

Bosch

In 1886, Robert Bosch founded the catchily-named “Workshop for Precision Mechanics and Electrical Engineering” in Stuttgart, Germany. In 1901, Bosch moved into automotive supplies and developed a reputation for innovation (2).

It now has over 400,000 employees and has a revenue of approximately 78.5 billion euros.

Milwaukee

Milwaukee is another all-American brand with a great pedigree. In 1918, Henry Ford was looking for someone to produce a portable power drill to use on his production lines. He approached A.H. Peterson, and the rest is history (3).

Milwaukee is now a major manufacturer, building over 500 models of tools and over 3,500 accessories.

Greenlee

In 1862, Pennsylvanian brothers Ralph and Robert Greenlee started making barrels just as the oil industry began in that great state. Demand skyrocketed, and the Greenlee brothers increased production to meet demand (4).

Their move into power tools came in 1874 when they invented the hollow chisel mortiser. This tool revolutionized the process of making mortise and tenon joints for the woodworking industry.


How to Use a Hole Saw

1. Choose a Hole Saw

It is important to choose a hole saw that is both the correct size and suitable for cutting the material you are working on. If the hole you create is too small, it can be difficult to enlarge it accurately as the pilot drill will have nowhere to grip.

Quick Tip

If you are cutting through metal or other hard materials, it is a good idea to use a bottle of lubricating oil to help it cut more smoothly. The oil helps reduce friction, which decreases heat build-up.

2. Prepare a Pilot Hole

Insert the pilot bit into the drill chuck and make sure it is straight and secure. It might seem strange to make a pilot hole when the hole saw also has a pilot drill in the center. However, the larger size of the hole saw will make it difficult to get a clear view of the hole while drilling. By making a pilot hole beforehand, there will be far less guesswork involved.

3. Put on Protective Equipment

Whenever you work with power tools, it is important to protect yourself. When sawing holes, particles are released into the air and you could potentially inhale them. Make sure you wear an N95 face mask, as this will filter 95% of contaminants out of the air as you breathe it in.

Make sure you also wear safety goggles, as you never know what debris might be kicked up while cutting.

4. Drill the Pilot Hole

Place the drill bit on the spot where you want the pilot hole to go. Make sure the drill is level so the hole is properly aligned. Press the trigger gently to allow the bit to turn slowly until it bites into the material. You can then increase your speed gradually until the drill penetrates deeper into the material.

When you have reached your desired depth, pull the drill back out. Remove the pilot bit and clean away any debris.

5. Insert the Hole Saw Into the Drill

Insert the arbor into the drill and tighten it either by hand or using a chuck key. Check that the hole saw is secure by seeing if there is any movement in the chuck. Also, check that the hole saw is straight. It will be too late once you have drilled the hole and discovered that it is off-center or at an angle.

6. Line the Hole Saw up to the Pilot Hole

Insert the pilot drill at the center of the hole saw into your predrilled hole. When you are satisfied that the hole saw is straight, press the trigger on the drill and apply some pressure as the bit turns slowly.

The hole saw’s teeth should make contact with the surface of the material evenly. If you are drilling through metal, you should consider adding some drilling oil or lubricant to reduce friction and protect your blade.

7. Increase the Speed

As the hole saw starts to bite into the material, gradually increase the speed. When you have drilled about halfway, stop the drill and remove the hole saw to free any trapped debris. This will help you maintain a clear line of sight and reduces heat buildup, which is one of the main reasons that teeth go dull.

8. Complete the Hole

For a smoother finish, it is recommended that you complete the hole from the other side using the same techniques. This is something professionals do and it shouldn’t be too complicated thanks to your pilot hole, so you could consider it if you are confident in your abilities.

However, if you are inexperienced or lack confidence, don’t attempt it because the holes might not align, which will result in an off-center gap. In this case, continue drilling from where you started until the hole saw cuts through to the other side of the material.
