Discover the performance of the 135° Split Point Black Oxide Drill Bit, a 1/4″ × 4″ high‑speed steel tool engineered for fast, clean holes in a variety of materials. Its straight shank and jobber length provide optimal control for professional workshops and DIY garages, while the black‑oxide coating adds durability and reduces heat buildup. Available now at Steep Falls Building Supply in Standish, ME, this bit is ready to tackle your next project.
Why it matters: The precision‑ground split point minimizes walk‑off, letting the bit start exactly where you mark, and four cutting edges deliver rapid penetration. Black‑oxide tempering lowers friction, improves chip evacuation, and extends tool life, making the bit perfect for wood, plastic, wallboard, plywood, and soft metals such as aluminum, brass, and bronze. Occasional use in stainless steel or harder alloys is also more manageable.
