Rated 5 out of 5 by from Great for spying When attached to alien technology that makes things spin incredibly fast you can cut a portal into a piece of wood through which you can spy on another dimension,.... or just push cables through. What ever floats your boat.

Rated 5 out of 5 by from What a bad review on Bosh I've now used this Bosh system for years, you have to be careful though because they bite the work piece and can make a mess or snap the drill bit, Though they last and last, with abuse on abuse, on all materials.

Rated 1 out of 5 by from Disappointed Used for cutting steel, first hole it only marked the steel then most of teeth ripped off. Stay clear.

Rated 1 out of 5 by from Look elsewhere I'd bought a few various sizes of this type of hole saw from Bosch, mainly going on the brand name and the fact of its 'power change' feature. The ones that I'd got produced very inaccurate, unclean cuts/ holes, they seems to wobble out of position, a standard hole saw with arbor works far better.

does this drill limestone?

Asked by: Stxx
Hi, these Holesaws can cut through a variety of metals, however we recommend for limestone the use of Carbide Holesaws.
