WNT makes big claims for its SCR Monstermill

WNT's SCR Monstermill solid carbide end mill is aimed specifically at high performance cutting applications on steel and cast iron components with hardness values up to 70 HRC.

The combination of its carbide substrate and Ti1200-based AltiN (Aluminium Titanium Nitride) coating allows SCR Monstermill cutters to withstand temperatures up to 1,200°C and have a greater resistance to tool wear. WNT suggests a tool life of some 60 m of cut length, even in the most abrasive of steel materials. SCR Monstermill cutters are available in a range of diameters between 3 and 20 mm, with a choice of short and long flute lengths as standard. Cutting fluids or cold air can be used for cooling and swarf evacuation and both can be delivered directly to the cutting edge via the internal coolant channels.
