Drilled through about a dozen holes in some tough cedar fence posts today and the 135° split-point tip bit in exactly where I aimed every time. The titanium coating still looks new after that abuse, which is more than I can say for my old set. Got my money's worth already.
After two weeks of drilling into brick and steel studs, the Quad Edge tip still grabs cleanly without walking. The titanium coating holds up way better than my old black oxide set ever did.
Put these bits through some heavy framing work and the QUAD EDGE tip still starts exactly where I aim it, no wandering. The titanium coating is holding up way better than my old black oxide set did after just a few weeks.
The Quad Edge tip really does start cleanly without walking, which saves me a ton of frustration on metal projects. After drilling a dozen holes in steel, the titanium coating still looks new.
These titanium bits have held up to daily drilling into metal studs without any chipping so far. The red helix design seems to pull the debris out better than my old bits. Definitely worth grabbing while they're on clearance.
The QUAD EDGE tip really does make starting holes on metal so much easier—no wandering bit. I've used a few of these on some pretty thick steel brackets and they're still sharp.
Drilled through a dozen holes in steel studs yesterday without any wobble or needing to swap bits — the RED HELIX design really clears the dust fast. This set should last me years.
The QUAD EDGE tip really does start precisely where I aim it, which saves me from drilling pilot holes on most jobs. I've put these through a dozen deck screws and some metal studs without any bit slipping or dulling so far.
I've been using these for a few weeks on various metal studs and the titanium coating is holding up way better than any other bits I've tried. The 29 pieces cover all the sizes I need for most of my jobs. A solid investment.
The Quad Edge tip really does give a precision start—no more walking on slick metal surfaces. I've been using these for a few weeks, and the titanium coating holds up way better than my old cobalt set.
