Kyocera TKT12717 Carbide Cutoff Insert 2mm Pvd

Product Description

The KYOCERA TKT12717 is a solid carbide cutoff and grooving insert in the GMM series, designed for precision parting and groove operations on CNC turning centers and lathes. Built with a micrograin solid carbide substrate and a PVD coating in the PR930 grade, this double-ended insert delivers consistent edge performance and wear resistance at the cutting zone. The MT chipbreaker geometry controls chip flow during interrupted or continuous cuts. With a 2.00 mm cutting width and a 4.30 mm cutting height, the insert suits tight-tolerance grooving and cutoff work on steel and stainless steel workpieces. It is clamped into compatible GMM-series toolholders and is appropriate for high-volume production environments.

This insert is intended for cutoff and grooving applications on steel and stainless steel. The PR930 PVD-coated grade is matched to ISO material group P (steel) as the primary workpiece material and ISO group M (stainless steel) as the secondary workpiece material. The neutral lead angle suits straight plunge grooving. Typical users include CNC machinists, toolroom technicians, and production turning operators running high-cycle parting operations where chip control and edge life are priorities.

Key Features

• PR930 PVD-coated micrograin solid carbide grade for extended tool life on steel and stainless steel
• 2.00 mm cutting width for precise parting and narrow groove profiles
• MT chipbreaker geometry promotes controlled chip formation and evacuation
• Double-ended insert design provides two usable cutting edges per insert
• Clamp-style holding method compatible with GMM-series toolholders
• Neutral lead angle for straight-plunge cutoff and grooving

Compatibility

Designed for use in GMM-series clamp-style toolholders. ANSI code GMM2020MTPR930 and ISO code GMM2020-MT identify compatible toolholder and insert seat configurations.

Installation Notes

Insert seating and clamping should be performed by a qualified CNC machinist or toolroom technician. Power down and lock out the machine spindle before changing inserts. Inspect the toolholder seat and clamp for wear or debris before seating a new insert. Follow the toolholder manufacturer's clamping procedure to ensure proper insert retention without over-torquing the clamp screw.
