10Pack 1/8in Shank HSS Rotary Burr File Rasp Drill Bits For Wood Stone Carving a

Description: 10Pack 1/8in Shank HSS Rotary Burr File Rasp Drill Bits For Wood Stone Carving a Features:High production efficiency, good processing quality, good finish, easy to use, safe and reliable, reduce labor intensity, and do not block.Suitable for wood carving, root carving, olive pit, sharp blade, durable.For jewelers, hobbyists, craft makers, modelers and more.Fast cutting and high hardness, suitable for root carving and carving of wood, aluminum and plastic.Applicable models: hanging mills, electric mills, drills, grinding tables and machines that can clamp rods with a diameter of 3mm can be used.Features of high-speed steel grinding head: The cutting edge is around the outer circle, which is used to polish the outer surface and process narrow grooves.Process characteristics: After repeated forging by air hammer, the grains (carbides) in the structure are refined, so as to achieve the effect of improving its super metal red hardness and wear resistance. The super fatigue fracture resistance of high-speed steel can be exerted at high speed. So as to prolong its service life, and finally achieve the purpose of saving time and energy consumption for customers.Machining process characteristics: The surface of the blade is repeatedly rough and finely ground by CNC machine tools, so that the surface finish reaches a high standard. At the same time, the imported micro digital control machine tool is used to open the blade (triangular edge and radian edge).Heat treatment process: high speed steel saw blade: generally salt bath quenching at 1205 ~ 1215 ℃, the metallographic level of the quenched structure reaches 10 ~ 11, and then grading isothermal, hot clamping and tempering 4 times, the tempering process is not allowed to overheat, and finally The tissue hardness is 64-66.5HRC.Application of high-speed steel electric grinding head: mainly used for groove processing and surface polishing of narrow and deep metal materials such as copper, iron, aluminum, alloy, etc. It can also be used for milling of non-metallic materials such as plastic and wood. When cutting off stainless steel materials, high-nitrogen or coated high-speed steel grinding heads should be used if high-speed steel is selected.Specifications:Material: high speed steelColor: silverlength; approx. 3.9 cm / 1.53 inchesShank Diameter: 3mm/0.11"Quantity: 10Package Included:10pcs*Grinding head for carving knife
