Thread Milling

New Indexable Thread Mills

Seco's newly designed indexable thread mill cutters and inserts represent another step forward for thread making applications. New inserts that are easy to load for the operator are double-sided and 40 mm long for increased thread lengths. In some cases, the same insert can be used for both left and right hand threads of the same pitch. The complete range is available in Seco's tough and wear-resistant grade F30M, a universal choice for all materials.

 

     

To hold the new inserts, Seco engineered multi-tooth cutter bodies for range of O.D. and I.D. thread making operations. Shell mill versions are available that hold up to six inserts for more agressive threading. Unlike tapping, milled threads can be machined to full depth, even in materials that have already been hardened with no sacrifice to the thread form, surface finish or accuracy. 

 

Solid carbide Threadmasterô Thread Mills

Seco's Threadmasterô mills thread holes as small as 4 mm while providing improved thread quality, productivity and lower cost per hole when compared to conventional tapping. These 2xD thread mills machine to 100% depth and feature a high helix angle for reduced cutting forces which can pose significant challenges when performing a final threading operation on potentially expensive components. The thread mills are also engineered to be very rigid and vibration resistant permitting higher feed rates and promoting longer tool life.

 

The TiCN coating provides both toughness and wear resistance for machining of all ISO materials and even high-temerature alloys. Toough coolant holes on thread mills of 8 mm shank diameter and larger aid chip evacuation, tool life and surface finish.
