Tap and Drill Bit Set: Tap thread size: M2 x 0.4, drill bit size: 1.6mm. High speed steel tool has high hardness, good toughness, wear resistance. Taps are prone to chipping or breaking due to speed overload or non-vertical tapping.
Spiral Point Tap: Spiral point design, downward chip removal. Suitable for processing blind holes and sticky materials. For tapping stainless steel, alloy steel, cast iron, ferrous and non-ferrous materials. Black nitrogen treatment greatly improve wear resistance, corrosion resistance and high temperature resistance.
Twist Drill Bit: Spiral chip space design for fast and clean chip removal. Sharp cutting edge provides smooth cutting and no glitches. Titanium coating provides excellent corrosion resistance, greatly improves wear resistance and hardness.
Usage of Tap: Used on drilling machines, tapping machines, CNC and milling machines. Use with tapping oil to get higher quality threads and more durable taps. Machine taps are suggested to be used with tap collets with overload protection.
Tips of Drill Bit: Suitable lubricant is conducive to cutting or cooling, making cutting easier, improving smoothness and dimensional accuracy. Select an appropriate feed rate and cutting speed to improve the tool life.
