Parlec T061615C2P Boring Insert Tcmt Solid Carbide

Product Description

The PARLEC T061615C2P is a TCMT-style solid carbide boring insert designed for precision internal turning and boring operations on CNC lathes and machining centers. This uncoated C2-grade carbide insert features a 60-degree triangular geometry with a positive rake angle of 15 degrees and a 7-degree relief angle, delivering clean, efficient cutting action. The 1/64-inch corner radius (0.0160 inches) supports fine finishing passes, while the compact 5/32-inch inscribed circle (0.1560 inches) suits toolholders configured for small-bore work. Machinists and CNC operators install this insert into compatible TCMT boring bars and cartridges as a direct replacement when the cutting edge wears.

This insert is suited for light-to-medium boring and internal turning across a range of workpiece materials including aluminum, cast iron, non-ferrous metals, and stainless steel. The uncoated bright finish makes it a practical choice for aluminum and non-ferrous applications where coated grades can cause built-up edge. It fits standard TCMT insert pockets in boring bars used on manual lathes and CNC turning centers in job shop, production, and toolroom environments.

Key Features

• TCMT insert style with 60-degree triangular shape for versatile boring and internal turning
• Solid carbide C2 grade, uncoated bright finish - well-suited for aluminum and non-ferrous metals
• Positive rake geometry (15-degree rake, 7-degree relief) reduces cutting forces on light cuts
• 1/64-inch (0.0160-inch) corner radius for fine finishing and tight-tolerance bores
• 5/32-inch inscribed circle (0.1560 inches) fits small-bore TCMT toolholders and cartridges
• Chipbreaker style P supports controlled chip evacuation in through-bore and blind-bore applications

Compatibility

Designed as a direct-fit replacement for TCMT06 insert pockets in standard TCMT-style boring bars and insert cartridges. Compatible primary workpiece materials include aluminum, cast iron, non-ferrous metals, and stainless steel (material codes K and M).

Installation Notes

This insert is installed and replaced by machinists or CNC tooling technicians. Always power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque driver or wrench for the insert screw to avoid cracking the carbide or stripping the pocket - do not overtighten by hand. Inspect the insert seat and pocket for chips or debris before seating the new insert, as contamination in the pocket affects surface finish and insert life.
