Surface Milling Cutter M35 Cobalt Drill Bit Set, HSS-Co Cobalt Drill Length Drill Bit, With Metal Shell, For Stainless Steel Wood Metal Drilling (Color : 13pcs drill set)

For CNC and other automatic routers, as well as portable routers for handheld and desktop installations. Such as woodworking engraving machine, trimming machine.● M35 cobalt. High-quality M2 HSS with 5% cobalt added to improve hardness and heat resistance. Rockwell hardness can reach up to 67. It has a faster cutting speed and a longer service life, which is 12 times that of an average HSS bit.● Self-centering. The guiding separation point of 135° rapid cutting is automatically centered and can be penetrated quickly under low pressure. The straight shank can be firmly fixed and accurately centered, suitable for standard drill chucks and conventional circular chucks.●Efficient drilling without walking. Remove debris and particles faster and easier.●The lowest drilling cost. The solid cobalt steel drill bit can be reground.●Split point. Drill directly to the required size without pre-drilling●Fully grounded. Heavy-duty fully ground body structure with minimal burrs and precise diameter.●Drills for metal. Suitable for drilling non-heat-treated metals with hardness less than HRC38, such as stainless steel, copper cast iron, galvanized pipe, iron and aluminum alloy. Not suitable for hardened steel/high carbon steel. If it cannot penetrate, try to adjust the speed.Package Included:25/19/25 PCS Drillpro M35 cobalt drill bit set1 PC metal box
