29PC Industrial Black & Gold Drill Bit Set — HSS, Round Shank, Indexed Sizes, Round Storage Box
Built for shops, installers, and serious DIYers, this 29-piece HSS drill bit set delivers reliable cutting performance with an industrial Black & Gold finish that reduces friction and resists corrosion. A round-shank, jobber-length design suits any 3-jaw chuck, while the indexed round box keeps sizes organized and easy to grab on the bench or in the van.
Key Advantages (multi-angle)
Cut quality & accuracy: 135° split-point starts fast with less walking; fully-ground flutes improve concentricity and chip flow.
Durability: Black oxide + gold finish enhances wear and rust resistance; HSS core maintains edge in wood, plastics, and light metals.
Productivity: Full 1/64" fractional coverage (1/16"–1/2") means fewer stops mid-project.
Usability: Round organizer box with indexed positions and size callouts speeds selection; round shank fits all standard chucks.
Value: Long service life and clean holes lower rework and cost per hole.
Typical Applications
Woodworking & cabinetry: pilot holes, hardware installs, dowel and shelf pin work
Electrical/HVAC: plastic enclosures, panels, light-gauge metals
General maintenance: brackets, fixtures, sheet goods, PVC and acrylic
Light fabrication: aluminum, brass, thin mild steel (use cutting oil)
For stainless/hardened steel, choose cobalt (M35/M42) bits.
