Carter ★★★★★

Installed these bits into the driver and they just ate through the steel shelf bracket without any wobble—the 135° split point actually grabs and starts cutting immediately.

Abigail V. ★★★★★

The Quad Edge tip on these bits is a game-changer—it starts cutting immediately with zero walking, even on slick stainless steel. I’ve already used them for drilling through a few thick brackets and the cobalt holds up perfectly. They’re pricier than standard sets, but the precision and durability are worth every extra dollar.

Emily ★★★★★

Finally, a drill bit set that doesn't quit halfway through stainless steel—the quad edge tip actually bites in cleanly without wandering. Went through a dozen holes in 1/8" sheet metal without a single chip or dull spot.

Matthew ★★★★★

Cobalt bits are a lifesaver when you're constantly drilling through hardened steel—these cut through like butter without wandering, and the 23-piece set covers everything I need for automotive work. The QUAD EDGE tip really does stay sharp longer than typical bits I've used.

Violet ★★★★★

Finally got through a 1/4" hardened steel bracket without smoking my drill—the quad edge tip really does stay sharp. The cobalt construction feels solid and the full 23 pieces cover everything I need for metal work.

Brian Z. ★★★★★

Needed to drill into stainless steel brackets for a railing repair, and this set chewed through them without any binding or overheating. The Quad Edge tip is definitely not just marketing fluff — it started cutting exactly where I placed it every time. Just wish the case had a tighter latch, but the bits themselves are flawless.

Kevin ★★★★★

Drilled through stainless steel bracket with almost no effort—the QUAD EDGE tip really holds up, and the cobalt finish sheds heat fast. Keeps cutting cleanly after a dozen holes.

Emma ★★★★★

Installed these in a tight engine bay with my drill driver and the cobalt edges didn't glaze over at all. The quad-edge tip bit into the steel bracket cleanly without walking.

Steven X. ★★★★★

Installed these bits in my drill driver yesterday and the QUAD EDGE tip punched through a steel bracket cleanly without wandering. Drilled through an old piece of stainless pipe today and it took the abuse without overheating. Glad I grabbed these on clearance.

Avery K. ★★★★★

Finally a bit set that handles stainless without binding or squealing—the cobalt edge is no joke. Drilled through a 1/4" bracket in seconds and the hex shank works perfectly in my impact driver.
