TY25S:Endmil、reamers and gravers are recommended.Excllent performance for high speed cuting. Suitable for cutting hardened steel,aluminum alloy and Titanium alloy.
TY20:Drill and endminlls are recommended.Suitable for cuting die steel、grey cast iron、austenitic stainles steel and heat resistant alloy.
TY05A:Drill、endmil and burr are recommended.Suitable for cuting non-ferous metal,aluminum,copper and graphite(coating in needed)
This grade recommendation is for your reference only, due to the shape of cutting tools and coating both have great influence on cutting tool's performance. Please go to specialty of grade for further information to assist your grade choice.
