High Speed Steel:
High speed steel construction provides ultimate durability, the cutting edge is hardened and honed for sharpness, chatter-free design with staggered cutting teeth ensure the precise countersinking and hole smooth clean.

Titanium and Nitride Coatings: Quality gold titanium and black nitride dual coatings can apply lubricant better for smoother drilling and is more durable and corrosion resistant than the regular surface.

Twist Design:
The split point tip and twist design increases cutting speed while easy self centering prevents walking. Say bye to all those chips and particles, with the twist design the drill bit can quickly clears them out, and leaves a clean, smooth hole.

Widely used for drilling stainless steel, aluminum alloy, iron, copper, brass, metal, wood and plastic materials. Suitable for hand drill, table drill processing equipment, etc. Suitable Lubricant is helpful for cutting or cooling, making cutting easier, improving smoothness and dimensional accuracy. It can help to extend the service life of tools in tapping operations.

NOTE: Not for using on concrete and masonry!
