## Description

Full description not available

## Features

- Professional high speed steel M42 (not M3) with cobalt 8% cutting teeth hardened to control the efficient and durable and reliable use on workpieces like sheet metal, Aluminium, wood, plastic, plasterboard, etc.. HSS M42 teeth is particularly good for high strength metal such as stainless steel (HSS M3 ones are good for middle strength metal but not high strength one) because HSS M42 contains cobalt 8%, which raises the hardness of the teeth. HSS M42 is about 20% more durable than HSS M3.
- 9-piece hole saws: 3/4"(19mm), 7/8"(22mm), 1-1/8"(29mm), 1-3/8"(35mm), 1-1/2"(38mm), 1-3/4"(44mm), 2"(51mm), 2-1/4"(57mm), 2-1/2"(64mm); 4-piece accessories: arbor 9/16"-1-3/16" with shank 3/8"; arbor 1-1/4"-6" with shank 7/16"; arbor adapter 1/2"-20UNF to 5/8"-18UNF; arbor center drill with shank 1/4". Center drills in this kit are all made of real HSS M2 and fully ground, while a lot of bi-metal hole saw kits are with low grade HSS center drills roll-forged.
- with max cutting depth 1-3/8" (35mm) and ideal for drilling on sheet metal (even high strength metal because of HSS M42 with cobalt 8% teeth), wood, plastic, plasterboard, Aluminium, etc.. Particularly for sheet metal: the cutting depth is 2mm to 5mm, depends on the hardness of the metal and taking hand drill or machine drill
- HSS bi-metal hole saws are much better than and totally different from any carbon steel ones (work on wood only, no metal).
- Packed in high quality carrying case.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good saws good value
*by N***Y on October 3, 2019*

I needed to cut a couple of different size holes in my metal barn. Having the full set made it easy to get the right size for the job. They cut through just fine. The only thing that stopped my progress was that the large adapter has a snap ring on it, and I didn't have the tool to remove it. It's all good now, because I not only have a nice set of saws, but I have a snap ring tool as well.

### ⭐⭐⭐⭐ Makes purdy wholes!
*by B***1 on August 13, 2020*

I'll confess that I almost never use a hole saw, but when I do need one it's usually to drill a hole through a 2x4 or a cabinet. So when I used this set to drill umbrella holes through my new picnic tables, I was surprised that the 2" hole saw blade couldn't quite make it through the 1-1/2" table top. Then I realized that a lock ring around the drill bit was preventing it. At first I thought that it was a poor design, but then I realized that by drilling the hole from both sides avoided splintering and produced a cleaner end result.So, I would have to say that this product does the job. As far a durability? That's a future review.

### ⭐⭐⭐⭐⭐ High quality!
*by R***K on March 14, 2019*

High quality hole saws in a very solid case. I have used them on wood with no issues. I have an automotive project these were purchased for to drill into metal, which I have not yet done, but expect good results. As a free bonus they sent me a rotary tool accessory kit that was unexpected and made this purchase an even better value. Thank you!
