Specification Brand : YOHANSEN BulletPoint1 : Premium Grade M2 Cobalt High-Speed Steel Construction: Built for durability, these drill bits are designed to handle tough materials like wood, plastic, aluminum, copper, cast iron, mild steel, stainless steel, sheet metal, and more. They deliver superior performance in demanding applications. BulletPoint2 : 135° Split Point Design: The innovative 135° tip ensures faster drilling by self-centering the bit, preventing walking or wobbling. Combined with a twisted blade design with deep grooves, these bits clear chips and debris efficiently—making them ideal for heavy-duty use. BulletPoint3 : Dual Coating Black and Gold: Featuring a premium gold titanium and black nitride finish, these drill bits retain lubricant better for smoother operation. This coating is 80% more durable and resistant to corrosion compared to regular black enamel finishes, ensuring long-lasting performance. BulletPoint4 : Versatile Compatibility: The 1/2-inch reduced shank design fits seamlessly with most drill presses and power tools. The tri-flatted shank end ensures a tight lock onto 3-jaw chucks, preventing slippage during operation for precise control.
