- Twist-away design and performance The precise 135 tip quickly penetrates the workpiece, prevents tool movement, and quickly removes chips and particles. Precision grinding ensures smooth chip discharge.
- Vertical operation Vertical operation can make the tip of the tool evenly stressed, which can avoid damage to the tip due to uneven force. The round handle design can be applied to more professional drilling equipment.
- Professional and versatile M35 cobalt high-speed steel is more suitable for machining hardened materials. It is particularly suitable for cutting hard metals such as stainless steel, cast iron, high-temperature alloys, titanium alloys, hard plastics and wood, and can also be used to cut softer materials.
