T-Max P Negative basic-shape inserts for high performance turning

T-Max® P is your first choice for general turning, stretching from small components to heavy machining. The inserts fit into all Sandvik Coromant high performance holding systems and can be used in a variety of applications in all materials. Geometries specifically designed for high pressure coolant are available for steel, stainless steel and HRSA materials. 



  • Dedicated grades and geometries for all applications and materials
  • Productive solution with wiper and Xcel technologies
  • Tools featuring high precision coolant for excellent chip breaking
  • Reliable and secure machining, even in roughing applications
  • Possibility to optimize by using damped Silent toolsTM



  • Double sided inserts with strong edges
  • Lever clamping for wet machining, RC-clamping for dry machining and short chip materials, Wedge clamp for improved accessibility
  • Precision nozzles and optimized geometries for high precision coolant machining



  • First choice for external turning
  • Internal turning of large diameter bores
  • Finishing to heavy roughing

Tool holding

T-Max P lever clamping system uses negative, single or double-sided inserts for both external and internal machining. It has a pivoted lever, which tilts by adjusting the clamping screw. The lever forces the insert backwards into the pocket, locating the insert firmly against two sides.

The following tool holders are available:


The -PMC, -MMC and –SMC geometries are available in grades GC4325 and 4315 for steel, GC2025 for stainless steels and GC1115 for HRSA materials. They are designed to excel in combination with the CoroTurn HP holders. High precision coolant gives perfect point of impact for finish to medium machining.
