The flutes of the drill bit act a passageway for chip extraction from the hole and for coolant to enter the hole.This drill bit is constructed of solid carbide tungsten steel with a bright finish coating, which give it very high surface hardness to help penetrate tough materials while highly corrosion reducing friction between bit and workpiece.These drill bits come with a twist design to increase cutting speed with an angled tip for precise self-centering and designed to cut holes faster as it prevents walking, clears chips and particles faster.Special left hand design can also be used with reversible drills with screw extractors to remove broken fasteners and to remove screws, bolts, and studs for home repairs, at your automotive garage, and more.Package Includes: 1PC(Sizes as you choose)==========Origin : Mainland Certification : Noneis_customized : YesModel Number : Left Hand Solid carbide drill BitDIY Supplies : MetalworkingMaterial : Tungsten SteelType : Twist Drill BitUse : Metal DrillingLength : 0.5mm-20mm Diameter
