KCS03001 Bi-Metal Cordless Smooth Cutting, 3 Stig, Hole Saw Kit

Nice kit, cuts very well and I haven't lost the spring yet. The spring is very helpful in clearing the polo bit out of the hole saw, saves a lot of time. The case is annoying, it seems too nice to throw away, but it is so wasteful on space. I would highly recommend you get some cutting fluid with these if you intend to drill sheet metal, they cut much better and last longer.

Perfect kit for professional use! most sizes that are needed for cable glands, Great ton have individual arbours so can quickly swap "bit". Only downside of these is you can't stack a smaller one and a bigger one to make a small hole bigger (and centering it) due tot he being the "stubby" version. you just have to eye-ball and persist with that.

If used carefully these are fine and worked well on some 316 SS tube. In challenging situations it was easy to knock the teeth off so we reverted to a TCT tipped set.

Why did you choose this product over others?: Compact and good quality.

Good kit very handy

Used all sizes on 12mm ply , cut either side on slow speed for 32/ 40mm , faster on the smaller cutters. still sharp, would never use on hard metal through but possibly aluminium sheet

I normally go for armeg cutters which may have a slight edge on speed. However these are built much, much better. The hole cutter sits on a collar/flange/base which is part of the pilot drill. This means no slipping like the armeg version. After a while the armeg one would skip past the grub nut and then is basically compromised and never works properly again. This can't happen with the starrett version the original and superior cutter now they have caught up on design.

This hole saw has only managed to cut 2 holes in a consumer unit before it’s worn out! Avoid at all costs
