It melts slowly as frictional heat is generated and provides continuous lubrication throughout low speed cutting operations. It significantly increases tool life and thread quality. CRC Trefolex Magic Cutting Compound is ideal for use with taps and dies, hacksaws, reamers and all hand tools. It allows for clean cuts with no tearing and is suitable for steel, aluminium, copper, brass and stainless steel.
