Countersink Drill with Brazing Carbide Blade Drill Drill Bit Set For Metal Cone Stage Drills Chamfering Milling Tool(20mm)

DrillsCountersink Drill with Brazing Carbide Blade Chamfering Milling Tool 90 Degree16mm 20mm 25mm 30mm 40mm For Metal-In order to ensure the firmness of the drill bit, we adopted a brazing method to weld carbide inserts. In this way, the drill bit can process harder metal (compared with HSS countersinks).But this will make the appearance of the drill bit not good-looking. We hope you don't mind. -Because the cutting edge of carbide material is very crisp, them machining environment needs to be stable to reduce beating.-It performs well when machining Non-ferrous metals, cast iron, General steel, alloy steel, etc.-Suitable for low rotating speed and low cutting allowance.Recommended RPM is about 200.Feed:K: 0.15~0.25N: 0.25~0.35M: 0.08~0.12P: 0.25~0.4Dimensions:16*12D*80L20*12D25*12D30*16D40*16D==========High-concerned chemical : NoneOrigin : Mainland Certification : NoneDIY Supplies : MetalworkingMaterial : Tungsten CarbideType : Countersink Drill BitUse : Metal DrillingLength : 16mm 20mm
