Parlec S124715TTP Boring Insert Solid Carbide Tin

Product Description

The PARLEC S124715TTP is a solid carbide boring insert designed for precision internal turning and boring operations on CNC and manual lathes. This square-shaped, SCMT-style insert features a positive rake angle of 15 degrees and a 7-degree relief angle, which reduces cutting forces and improves surface finish in a range of ferrous and non-ferrous applications. The insert carries a multilayer TiN/TiC/TiN coating that extends tool life by resisting heat buildup and abrasive wear. Machining professionals and toolroom technicians install this insert into compatible SCMT-style boring bar holders for tight-tolerance bore finishing work.

This insert is suited for light to moderate boring cuts in production and job-shop environments. With a 0.5-inch inscribed circle and a 0.047-inch corner radius, it is well matched to smaller-diameter bore applications where dimensional accuracy and finish quality are critical. The 90-degree included angle and positive rake geometry help minimize radial cutting pressure, making it appropriate for workholding setups with limited rigidity or for thin-walled workpieces requiring controlled chip formation.

Key Features

• SCMT insert style with square shape and 90-degree included angle
• Solid carbide substrate with multilayer TiN/TiC/TiN coating for extended wear resistance
• Positive rake geometry at 15-degree rake angle reduces cutting forces
• 0.047-inch corner radius for improved surface finish and edge strength
• 0.5-inch inscribed circle (IC) fits standard SCMT boring bar pockets
• 0.188-inch thickness provides insert stability under interrupted and continuous cuts

Compatibility

Designed as an OEM-style replacement insert for SCMT-style boring bar holders and insert pockets accepting a 0.5-inch IC square insert with a 0.216-inch hole diameter.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and locked out before changing inserts. Seat the insert firmly in the pocket and torque the clamping screw according to the boring bar manufacturer specifications. Inspect the insert pocket for chips or debris before seating to avoid seating errors that can affect bore geometry.
