Product Overview

Tired of drill bits that dull quickly and snap under the slightest pressure. Then step up to DEWALT Black Oxide Drill Bits. These industrial-grade twist-drill bits are cut from super-hard, resilient black oxide for the ultimate in durability and strength. Each bit features a 135-degree split point for enhanced hole-drilling performance, including quick starts and clean, burr-free holes. For use in wood, metal, plastics and fiberglass.

  • 135-degree split point drills on contact and prevents walking
  • Parabolic flute design improves chip ejection in metal and wood drilling applications
  • Black oxide coated for greater wear resistance
  • Helix is 31-degree which minimizes the over aggressiveness of a true parabolic flute

Unlike the previous glowing reviews, I had a mini-disaster with this product. It was not hardened, and it bent upon taking it out of the package. After careful rebending, I was able to make it appear to be straight enough with the drill with the drill running, and then within a few seconds of use, it broke. Granted it is a thin, small bit and perhaps it was not hardened in the manufacturing process, but it was both a major disappointment and a waste of money.

Returned this product because it could not drill through the wood I needed to get through. This drill bit was suggested by a Home Depot associate. It just did not seem to have a sharp enough tip.

Rated 5 out of 5 by from Perfect bit for the job Building a wheelchair ramp. Easily bit through 4x4 and 2x6 treated material, especially in my hammer drill. A 7/16" bit is perfect for accepting 3/8" carriage bolts.

Rated 1 out of 5 by from Rounded The rounded end that goes inside the drill is not good at all. I like it better when it is angled, because it tends not to slip.

Rated 4 out of 5 by from Exhaust work Needed the length to get a hole drilled into the manifold to be able to get the bolt to hold the exhaust tight to the manifold
