⛱️ Driak 16 30 5mm 5 20mm Umbrella Chamfer: A Versatile Solution for Precise Chamfering Review

This Industrial and Scientific drill bit was a complete letdown. After I put it to the test, it broke within minutes of use. The only pro I can mention is that it had a unique design, but that did not make up for its subpar performance. The cons heavily outweigh any positives, and I would not recommend this to anyone in need of a reliable and sturdy drill bit. Don't waste your money on this product.

I ordered these to help me with a project I'm working on to create funnel holes in the bottom of my dog holes on a carpentry machine. Ideal bits for the job - they are very dense and strong. Very well made and arrived very quickly.

I've never seen anything so boring. The cutting edges are literally blunt. Just cuts the ground. So that all 3 are not sharpened, there must be ZERO quality control. I will try to sharpen them myself as I need them for a project and can't wait to replace them. If I can't, I just send them back.
