Wale Posted November 27, 2019 Share Posted November 27, 2019 (edited) I need to drill a number of holes in hardened steel aka bumper beams. Can anyone recommend some good affordable solutions? Ive read about using carbide masonry bits https://drilling-it.com/best-router-bits-sets-reviews/ or carbide glass/tile bits. Buying a dedicated set of carbide bits is about 10x the cost...
