Pulled these out for a stainless steel sink install and the QUAD EDGE tip bit in cleanly without wandering—no pilot hole needed. They're holding up way better than my old set on the second job already.
Had to drill through some hardened steel brackets earlier today, and this set cut through like they were butter. The cobalt alloy really holds its edge longer than my old bits.
The QUAD EDGE tip started biting into my stainless steel bracket immediately without any skipping. These cobalt bits definitely justify the price for anyone doing serious metalwork.
Was a bit skeptical about the price, but the Quad Edge tip punched through an old hardened steel bracket without even slowing down. The cobalt alloy really does seem to hold its edge longer than the cheap sets I've burned through before.
Drilled through a stack of stainless steel brackets without any bit wandering thanks to the 135-degree split point. Running them at lower RPM in my cordless driver, they stayed cool and sharp for over 50 holes. Solid set that’ll last a while.
The quad-edge tip on these bits bites into hardened steel far better than my old set ever did. I’ve put them through a dozen holes in thick angle iron without any noticeable dulling, and the cobalt construction seems to handle the heat like a champ.
Used these to drill through stainless steel brackets that usually eat bits for breakfast—each hole was clean and fast. The cobalt material seems to hold its edge far longer than my old set. Glad I grabbed them at this clearance price.
The quad-edge tip bit into the hardened steel bracket without walking at all, which saved me a ton of time. I've drilled about twenty holes so far and the edge still feels razor-sharp.
Used these on stainless steel for the first time today. The cobalt alloy cuts way faster than my old bits, and the 29-piece set covers every size I could need.
The quad-edge tip on these bits started cutting through a stack of old brake rotors without any wandering at all. They stayed sharp after a dozen holes in hardened steel, which is way better than my old set.
