### ⭐⭐⭐⭐⭐ Good quality
*by K***N on January 19, 2026*

Bits work great and at a great price

### ⭐⭐⭐⭐⭐ Straight and Sharp
*by G***N on February 12, 2026*

So far, these seem to be well made, straight and sharp. They drill aluminum cleanly but I haven't used them on steel yet. So far, so good.

### ⭐⭐⭐⭐⭐ Excellent Performance
*by D***R on November 7, 2023*

I found these drills to be outstanding in low carbon steel - easily out performing the brand purchased from my local “home improvement “ store. I am knowledgeable about cutting tool design - and given my high level of satisfaction I thought I should offer some details to support my 5 star review. 1 first use : the drills were stable in cut and made accurate sized holes and required minimum feed force 2. Close review: these drills have well manufactured tip grinds. I have found many drills have poor relief grinds ( behind cutting edge) or poor lip to lip run-out - both of which cause instability and poor chip morphology when in cut. Easily identified under magnification but can be simply observed with significant heat generated in cut to the workpiece. ( a properly made drill applied with correct feeds and speeds will impart more heat to the chips produced) The flutes are also polished. This allows the chips to easily flow out from behind the cutting edge. I highly recommend.
