Kyocera TBR01611 Turning Insert Pcd CNMM431MSE KPD001

Product Description

The KYOCERA TBR01611 is a single-tipped polycrystalline diamond (PCD) turning insert in the CNMM431MSE geometry with grade KPD001. It features an 80-degree diamond insert shape, a 1/2-inch inscribed circle, and a 1/64-inch (0.0156-inch) corner radius. The insert is uncoated with a honed cutting edge and a negative rake angle, making it well-suited for high-precision material removal on difficult-to-machine workpieces. Holding method is clamp and pin. It is used by machinists and CNC operators running turning, boring, facing, and chamfering operations on non-ferrous metals and superalloys.

This insert is designed for external turning, internal facing, boring, chamfering, and facing applications. Primary workpiece materials are non-ferrous metals and superalloys, with superalloys listed as a secondary material class. The CNMM style with neutral hand orientation allows flexible application across a range of tool holders conforming to ANSI and ISO standards. ISO designation for this insert is CNMM120404M-SE. It is a multi-use insert appropriate for production and job-shop environments where PCD tooling is specified for demanding materials.

Key Features

• Polycrystalline diamond (PCD) insert material — super micrograin grade KPD001
• 80-degree diamond insert shape (CNMM style) with neutral hand orientation
• Uncoated, bright finish with honed cutting edge for clean chip formation on non-ferrous and superalloy workpieces
• 1/2-inch inscribed circle (12.70 mm) and 3/16-inch insert thickness
• Negative rake, zero-degree relief angle (clearance code N, tolerance code M)
• Multi-use capability: external turning, boring, facing, internal facing, and chamfering

Compatibility

Compatible with ANSI and ISO standard CNMM-style tool holders designed for clamp and pin insert retention. ISO designation CNMM120404M-SE. Suitable for operations on non-ferrous metals and superalloys.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or replacing the insert. Secure the insert using the appropriate clamp and pin hardware rated for the CNMM holder style — do not overtighten the clamp screw beyond the tool holder manufacturer specification. Verify insert seating and tool nose runout before returning the machine to operation.
