- Quality high speed steel ensures the bits super hard, sharp and cutting effectively with impressive cutting performance in metal, plastic, and wood etc with long tool life
- All drill dimensional & tolerances conform to ASME/ANSI B94.11M or USCTI – United States Cutting Tool Institute drill standards
- Fully ground process ensures excellent chips moving, and 135 deg chisel angle with split point provide accuracy start for quick penetration without Walking and less Logging
- Precision treatment makes drills durable toughness, withstands heavy duty operation, resists corrosion and lubricates the drill bits better for cutting smoothly
- Stub Drills were developed for screw machine operations where regular drills are too long for small spaces; The short length reduces breakage and runout
