The Magafor center drills are particularly effective thanks to their unique ground spiral flutes. Hard'X: AITiN with a high hardness (3,700 Hv), this coating shows a high thermic stability and an excellent protection against heat and wear. Ideal for dry machining — high speed cutting — in treated steels and dies. The higher concentration of aluminum in the coating creates for a lower friction coefficient providing greater tool life than traditional TiAIN offerings. All metric center drills are available within 2 weeks. Call for information.
