Review on TopLine Drill 0 1590 Bright Finish by Matthew Burnett

Good price, great service, lousy bits. The project required drilling 1000 holes in 3/16-inch 5052HB aluminum, a relatively soft material. Using a standard drill motor, medium speed and medium pressure, the first drill bit broke after only a few seconds of drilling. It was NOT a hammer drill, nor was the drilling vertical. I doubt these are American drills. They're more like cheap Chinese steel. Luckily I have 5 more and will update this review if anything else breaks. very good and still produces chips for a long time after a few hundred holes the third cutter is still strong after a few hundred so the first cutter must have been a manufacturing fault would buy again.
