Superior gold titanium and black nitride dual coating finish holds up lubricant better for smoother drilling, and is 80% more durable and corrosion resistant than regular black enamel finish

135° Split point design at tip increases cutting speed with self-centering feature and prevents drill walking or wobbling

【Process Treatment】Titanium coated surface prevent rusting, which increase the hardness of the drill bit and reduces heat buildup, make the twist drill bit more wear-resisting for longer life.

【Twist Design & Performance】The 135° fast cutting point is automatically centered and penetrates quickly with less pressure,Prevent walking, clear chips and particles faster. Produced by precision fully ground which ensures chips move smoothly.

【Premium High Quality】Drill bits made from high speed steel for strength and durability. Screwdriver Bits are made of S2 steel material for ultimate durability.
