Uxcell 4.5mm Solid Carbide Left Hand Spiral Flutes Twist Drill Bit for Stainless Steel

Constructed from micro grain YG6X/C3/K10 tungsten carbide, the drill bit is hardened up to 91HRA, wear resistance, corrosion resistance, heat resistance, and good bending strength. Used for semi-finish and finish cutting of stainless steel, alloy steel, cast iron, titanium alloy, non-ferrous metal, copper, plastics. Suitable for drilling abrasive materials when drilling accuracy must be maintained. Can be used in high temperature drilling applications. Carbide tool offers long tool life and faster cutting speeds than other substrates, and it is higher hardness but is more brittle. Carbide material with good cutting performance, can ensure high work efficiency.
