Allied Machine 7C129P-0107 Spade Drill Insert 1-7/32 in

Product Description

The ALLIED MACHINE AND ENGINEERING 7C129P-0107 is a solid carbide spade drill insert designed for high-performance drilling in steel and hard materials. It carries a 1-7/32 inch diameter, a 140-degree point angle, and belongs to the GEN3SYS XT series. The insert is finished with an AM300 PVD coating, which reduces friction and extends tool life in demanding cutting applications. Seat Size 29 ensures precise fitment in compatible GEN3SYS XT spade drill holders. This insert is used by machinists and toolroom professionals working with CNC machining centers, drill presses, and manual boring equipment where repeatable hole geometry is required.

The 7C129P-0107 is suited for production drilling operations in steel and hard workpiece materials. The GEN3SYS XT platform is engineered for aggressive feed rates and deep-hole drilling where insert replacements must be fast and indexing must be consistent. The AM300 PVD coating provides added protection when cutting through abrasive or work-hardening steels. This insert is a direct drop-in replacement for worn GEN3SYS XT Seat Size 29 inserts without requiring holder replacement or special tooling adjustments.

Key Features

• 1-7/32 inch cutting diameter for precision bore sizing
• 140-degree point angle reduces thrust and improves chip formation in steel
• Solid carbide construction at manufacturer grade C1 (K35) for rigidity and wear resistance
• AM300 PVD coating extends insert life in steel and hard material applications
• GEN3SYS XT Series, Seat Size 29 for repeatable indexing in compatible holders
• Single-piece replaceable insert design minimizes downtime during tool changes

Compatibility

Designed for use with GEN3SYS XT spade drill holders accepting a Seat Size 29 insert. Primary workpiece materials are steel and hard materials (material codes P and H).

Installation Notes

Installation is performed by machinists or toolroom technicians. Before changing the insert, ensure the machine spindle is fully stopped, locked out, and the holder is removed or secured per shop lockout-tagout procedures. Seat the insert flush against the holder pocket and torque the retention screw using the manufacturer-specified driver to avoid cracking the carbide. Inspect the holder seat for chips or debris before inserting a new blade, as contamination will affect runout and hole quality.
