Milwaukee Hole Saw Kit – 49-22-4185 28 Piece
At the top of the list is the Milwaukee 49-22-4185 28-Piece All Purpose Professional Hole Dozer Ice Hardened Hole Saw Kit. It includes a staggering 22 ice hardened bi-metal hole saw blades nicely packed in a compact plastic carrying case together with other accessories. The hole saws feature the latest and strongest tooth form in the industry known as the RIP GUARD™. They also have a Limited Lifetime Tooth Break Warranty. However, that does not mean that the teeth are weakly designed. As a matter of fact, each tooth is built with more steel along with 8% cobalt behind the cutting edge for added strength. This guarantees increased productivity on the worksite, as well as continued hole quality. The hole saw blades can cut holes as small as 3/4 inch and as large as 4-3/4 inch in width.
One of the most time wasting activities when using holes saws is removing stuck plugs especially when cutting through sheets of wood. On average, a minute is wasted trying to remove a stuck wood cut.
To reduce this downtime and increase productivity the Milwaukee hole saw blades feature an all-access slot design that allows full access during plug removal. As a result, plugs are removed easily and faster by applying leverage at multiple points hence saving time and increasing overall jobsite productivity. Lastly, the milwaukee hole saw kit includes 3 quick change arbors with 1/2″ shanks for the different hole saw sizes.
Lenox Big Daddy Hole Saw Kit
Packed in a nice little molded-plastic blue and white carrying case, the LENOX Tools Bi-Metal Speed Slot Hole Saw Kit delivers among others 20 pieces of commonly used bi-metallic hole saws. The sizes span between 3/4 inches and 4-3/4 inches. The hole saws are uniquely designed with a speed slot for easy removal of plug. More precisely, the speed slot on each saw has a copyrighted staircase design that allows you to easily pry out stuck wood plugs with an ordinary flat-blade screwdriver.
All the saws have large sharp teeth that are optimized to cut more efficiently and last for many cuts. They are also constructed with a thicker wall for increased strength and durability. As far as cutting speed is concerned, the hole saws brag the T3 technology in their construction which makes them cut through metal more easily while guaranteeing a life that is twice as long as the previous generations. Three snap-back arbors (1L,2L, & 6L) with 1/2″ shank and three pilot drills are also included in the assortment.
Bosch Hole Saw Kit – HB25M Bi-Metal 25-Piece Hole Saw Master Set
Albeit quite bulky, the Bosch 25-Piece Master Bi-Metal Hole Saw Kit HB25M contains among other accessories 11 different sizes of hole saw blades. The sizes span between 3/4 inches and 3 inches. Unlike other ordinary hole saws that burn their way into wood producing loads of smoke, the bosch HB25M saws are made of 8% cobalt alloy for higher heat resistance thus producing less or no smoke. The alternating sizes of the teeth, otherwise referred to as the progressor tooth design, allows the saws to cut a lot faster with more precision. The large teeth are optimized for fast clean cuts in thick materials while the short ones are optimized for thin materials.
Also contained in the kit are 4 small adapters and washers, 7 larger adapters, a quick change mandrel, and 2 pilot bits. The adapters are installed onto hole saws so that you can use them with the quick change arbor. One beautiful thing about Bosch’s hole saws design is that the saws can be used with standard arbors from other brands. All you need to do is to remove the adapter and install the hole saw directly onto the standard mandrel and you are good to go.

Both mandrels have hex shanks of different sizes. The shank of the larger mandrel is 7/16 inches in size while that of the smaller arbor is 3/8″ inches
The two injector buttons or prongs on the larger mandrel keep the hole saws in place for a more secure operation. In order to install a hole saw, you first need to pull back the mandrel, attach the hole saw, then snap the injector buttons into the two holes on the hole saw to lock it. All these accessories are packed nicely in a fantastic molded-plastic carrying case that keeps it compact on your workbench.

How to Assemble a Hole Saw Kit
- Select the appropriate size of the hole saw.
- Pick the mandrel that is the proper size of the hole saw. Normally, there are different mandrels for different hole saw size ranges.
- Put the hole saw into the mandrel and screw it on.
- Take two open-end wrenches: one the size of the arbor shaft and another one that can hold tight the hole saw on its flat grooves at the bottom.
- Use the two wrenches to tighten the hole saw onto the mandrel so that it doesn’t come loose when you drill.
- Pick a drill of your choice and install the mandrel of the hole saw onto the drill and tighten.
- You are now ready to start drilling nifty circular holes with your set of hole saws!
- Repeat the procedure if you want to change the hole saw and/or mandrel
How to Use a Hole Saw
After the assembly of the hole saw kit, the next step is to use it to drill holes. While most handymen know how to use a hole saw, a good number does not or rather does not know how to use it effectively and safely. The following is a procedure for using a hole saw.
- Warning: Ensure that you wear protective clothes, glasses, and heavy-duty pair of gloves before you begin to drill holes.
- First, identify where you want to drill a hole and mark the center with a pencil.
- Drill a pilot hole into the mark with a drill bit.
- Fit the hole saw and mandrel assembly into the drill. Ensure that the pilot bit sticks out further than the hole saw itself.
- Grip the drill tightly perpendicularly onto the material you want to drill through the pilot hole.
- Start to operate the drill. The pilot bit will guide the drill.
- If you are working on a thick sheet of wood, just drill about halfway through and flip it over. The pilot hole will give you a perfect index to finish the cut.
- Drilling wood from both sides gives you a clean cut that does not have any tear out.
- Hole saws larger than 3″ tend to grab when you start to cut in. That pull may cause strain or even twist on your wrist. For such a case, use a drill that has a handle on it so that you can have both the drill and the handle against your body to keep it from twisting.
