Hex Shank Drill Bit 3/32 in Silver & Gold

Drill bits with a 3/32-inch diameter and a 1/4-inch hex shank featuring a black and gold (often described as gold oxide or titanium aluminum nitride) finish are designed for high-performance drilling. The gold coating typically indicates a surface treatment that reduces friction and increases heat resistance, while the hex shank allows for quick changes in impact drivers and prevents slipping in standard chucks. These bits often feature a 135° split point tip, which helps prevent "walking" (slipping off the target) and allows for self-centering on hard materials like stainless steel and iron.
