Birtechway Sharp Durable Triangle Head Power Drill Bits

Triangular alloy bit - The surface of the bit is finely polished and a new electroplating process is adopted to prevent rust and extend the life of the bit. Bit turning tool - improves work efficiency, has higher hardness and wear resistance than ordinary drill bit. Small resistance, smooth chip removal, smooth cutting surface, no residue, good cutting performance, can tap to the blind hole button. Flexible use, high processing efficiency, good stability, safe and reliable, wide use, low processing cost, can be applied to a variety of jobs. The application of nitriding improves the abrasion performance, surface hardness, fatigue limit and erosion resistance of tapping.
