Sutton HSS and cobalt lathe tool bits are precision-ground blanks and shaped tool forms used in tool holders on manual engine lathes, turret lathes, and CNC turning centres. The M42 cobalt grade provides superior heat resistance for hard turning and difficult materials.

Where this product is used

Used in toolrooms, engineering workshops, and turning shops for external turning, boring, parting, and threading on manual and semi-CNC lathes.

• External turning, boring, and facing operations on manual engine lathes in toolrooms, jobbing shops, and maintenance engineering.
• Precision form tool grinding and regrinding where the operator needs a blank from which to grind a custom cutting profile.
• High-speed turning of hardened alloy steels using M42 cobalt-grade tool bits that maintain hardness at elevated cutting temperatures.

Selecting the right option

Standard HSS tool bits (M2 equivalent) suit most general turning applications in mild and medium alloy steels. M42 cobalt bits are worth the premium for production turning of high-alloy, stainless, and heat-resistant materials. Confirm the cross-section and length match your tool holder capacity.
