carbide rotary sets(8pcs)

FEATURES AND DIRECTIONS FOR USECarbide rotary file is also called Carbide high speed cutter,or Carbide mould cutter.In comparatively developed countries in the world the files have already found wide application and have been regarded as an important means for raising production efficiency and realizing the mechanization in bench work.The file, as a necessarytool for fitters and repairmen has gradually gone popular in our country in the recent years.The main features of the file are as follows:capable of machining various metal(including defferent quenching steel)and nonmetal materials(such as marble,jade and bone)with hardness up to HRC70to replace small shank grinding wheel in most instances, no dust contamination producedhigh production efficiency,several tenfold the manual operated file,and 5-10 fold the small shank grinding wheelgood machining quality and high smoothness suitable for machining various mould cavity with high accuracylong service life,ten times the high speed steel tools and 200 times the small grinding wheel in durabilityeasy to handle and operate,safe and reliable,able to reduce labour intensity and improve working conditionhigh economicbenefit,may have a 10% reduction in comprehesive process costIn general,the carbide rotary files can be driven by hand electric or pneumatic tools(or mounted on machine tool).Usually,the rotational speed of electric or pneumatic tool should be 6,000-50,000rpm.The file must be correctly clamped during operation.To avoid reciprocally feeding,reverse mill is more favourable.To protect your eyes with protective spectacles and prevent chip from splash at the same time.
