Hole saws are ideal for woodworking, plumbing, electrical, or masonry work and they offer aggressive tough material penetration due to their high heat and wear resistance properties.

Additionally, they remove the material smoothly because they have an aggressive kerf clearance. This produces very smooth edges on the drilled hole. A kit gives you multiple hole saws, arbors, drill bits, and other components required for the job. 

That said, these kits are available in different piece numbers, sizes, and materials. For this reason, we have detailed all this info the review below to help you pick the best hole saw kit that fits your project requirements.

  • Number of Pieces: 28
  • Materials: Bi-Metal (Cobalt)

Milwaukee’s 49-22-4185 takes the best overall spot because it is a comprehensive set that contains 28 pieces. These include 22 hole saws that vary in size from 3/4 – 4-3/4 in., 3 arbors, and 3 drill bits.

The hole saws are built using a durable bi-metal (with 8% cobalt) and are ice-hardened via a proprietary cryogenic hardening process. This process is more effective than heat treatment and unlike surface coatings, it hardens the material to the core.

Essentially, it minimizes austenite (soft metal) and creates more martensite (hard metal). This increases the saw’s lifespan by up to 50%.

Aside from that, the saws have precision-ground tooth geometry that gives faster-cutting performance while their deeper gullets extract chips faster. They also have a positive rake angle that cuts more aggressively.

Other features include a radiused back face that minimizes stress on the teeth and a functional slot geometry that easily fits a screwdriver for easy plug removal after drilling through wood. On the downside, this kit is very expensive.

Pros:

  • Comprehensive 28-piece set
  • Durable bi-metal construction
  • Ice hardened for extra toughness
  • Precision-ground tooth geometry for faster cutting
  • Positive rake angle for aggressive cutting

Cons:

  • Expensive

How to Buy the Best Hole Saw Kit

How to Buy the Best Hole Saw Kit

Photo: DrillPro

1. Size

Hole saws are measured in inches by their diameter size. A kit usually has more than one saw and you should check these sizes to match them with your project requirements.

Ultimately, the kit that has more pieces is better because it gives you more sizes to work with. That said, with its 22 hole saws, Milwaukee’s 49-22-4185 is the best fit for most projects.

2. Number of Pieces

Following up on the point above, there is the number of hole saws and there is the number of pieces per kit. Some units have a large set but with fewer hole saws and these usually add on important pieces such as installation plates and Allen wrenches.

More pieces are better but this usually comes at a high price. Therefore, you should look for the specific tools that you need for your project, then buy the kit that has them.

3. Materials

The material used to make the hole saw determines its application area. For instance, High-Speed Steel (HSS) is recommended for cutting through wood, fiberglass, PVC, and other softer materials.

Bi-metal saws with cobalt are very good at heat dissipation and this makes them ideal for cutting harder materials like steel and aluminum.

Carbide-tipped saws maintain their sharpness for a long time and are ideal for cutting through tiles, bricks, and stones. This should guide you to pick the best one for your project.

4. Cutting Efficiency

Cutting efficiency can be looked at in different aspects. Tooth geometry/design, for instance, should be aggressive, cups and gullets should be deep for faster extraction, and the rake angle should be positive for aggressive cutting.

Such features are highly recommended and can be found in Milwaukee’s 49-22-4185.

5. Durability

Certain features make a hole saw kit highly durable. For instance, ice-hardening using the cryogenic treatment process makes the hole saw very durable because it hardens the metal material to the core. This can be found in Milwaukee’s 49-22-4025.

On the other hand, toughened backing plates support the cups to prevent warping and this is especially important if they are deep cups.

6. Replaceability

Replaceability determines the serviceability and consequently, the lifespan of the hole saw kit. With that in mind, the kit should have easily replaceable saws when they become dull, as well as easily replaceable center bits in case they break.

This modular design allows you to use the kit for longer before all the components wear out. For this, be sure to check out the Gorchen 521.

How to Use a Hole Saw

How to Use a Hole Saw

A hole saw must be attached to a mandrel/arbor before mounting it to a drill driver. Therefore, to use it, you must first carry out this step.

  • Begin by selecting the right hole saw size from your kit then insert the mandrel’s bit through its center hole.
  • Fit in the mounting plate then screw it tightly to the mandrel. If it has a quick-change system, press the button to install it. You should check the mounting instructions on the user manual for proper guidance.
  • Once set up, start drilling at a slow speed and hold it tight as you guide the pilot bit into the material. Maintain this speed until the hole saw touches the surface and marks out the circle.
  • After you’ve confirmed it is drilling at the right spot, run the driver at a higher speed so that you get a clean cut.
  • If the material is too thick, remove the hole saw after digging in a few inches to clear out chippings and cool it off a bit. You can also drill from both sides as you head towards the middle.

Conclusion

All in all, the primary determining factors in selecting the best hole saw kit are the number of pieces, material, and cutting efficiency.

Considering these, Milwaukee’s 49-22-4185 takes the overall best spot because it is a comprehensive 28-piece set with durable and high-performance hole saws.

For woodworking, you don’t have to spend a lot of money to acquire an expensive kit. Black & Decker’s 71-120 is quite affordable and it has a unique tooth design for aggressive cutting.

If you are very tight on cash though, we highly recommend EDMBG’s 23097-CHIS801 because it is very affordable. However, this can only be used to cut through wood.
