Drill Bit 1.0-9.0mm Solid Carbide Core Drill Bits for Hard Metal Drilling Tools 3D Whole Tungsten Steel,3.9mm,Round

DIY Supplies:MetalworkingType:Twist Drill Bitlength:38-84mmMaterial:Tungsten SteelUse:Metal Drilling1. Carbide tools are good at working with wood, aluminum, copper, MDF, carbon steel, alloy steel, hardened steel, cast iron.2. It is very suitable for chamfering, V-groove engraving and centering.3. The tool is made of very tough particulate cemented carbide, which is wear-resistant and provides high cutting performance.4. The coating lubricates the milling cutter at high temperature to obtain stability, has excellent wear resistance at high cutting speed, and is more heat-resistant.5. Advantages: sharp and wear-resistant, smooth drilling, making cutting more efficient and cleaner surface.
