Allied Machine 7C129P-0108 Spade Drill Insert 1-1/4 in

Product Description

The ALLIED MACHINE AND ENGINEERING 7C129P-0108 is a solid carbide spade drill insert designed for high-performance drilling operations in steel and hard materials. Engineered to seat into GEN3SYS XT spade drill bodies at Seat Size 29, this insert delivers consistent, repeatable hole quality in demanding production environments. The 140-degree point angle promotes aggressive material penetration and reduces thrust forces at entry. An AM300 PVD coating — manufacturer grade C1 (K35) — provides thermal resistance and extended tool life when cutting through ferrous and hard workpiece materials. Machinists and toolroom technicians working in high-volume metal-cutting applications rely on this insert for dimensional accuracy and long run life.

This insert is suited for CNC machining centers, drilling stations, and manual machines configured with Allied Machine GEN3SYS XT spade drill holders. It is intended for primary workpiece materials coded P (steel) and H (hard material), making it applicable across job shops, aerospace machining cells, and production facilities where consistent bore geometry is required. The solid carbide construction and PVD coating make it particularly effective in interrupted cuts and high-feed drilling programs where coated HSS or brazed inserts would wear prematurely.

Key Features

• Solid carbide construction with AM300 PVD coating for extended wear resistance
• 140-degree point angle reduces entry thrust and improves chip formation
• GEN3SYS XT series compatibility — fits Seat Size 29 spade drill bodies
• Manufacturer grade C1 (K35) carbide rated for steel and hard material applications
• Compact insert geometry: 1.75 inches length, 1.63 inches width, 0.75 inches height
• Single-piece packaging suitable for individual replacement or toolcrib stocking

Compatibility

Designed for use with Allied Machine and Engineering GEN3SYS XT spade drill bodies accepting a Seat Size 29 insert. Confirm holder seat size before ordering — this insert is not interchangeable across seat size designations.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician following the drill body manufacturer's torque and seating procedures. Ensure the spindle is fully stopped and the machine is locked out before removing or installing any cutting insert. Inspect the insert pocket and seating surfaces for chips or debris before seating the insert, as contamination can cause improper seating and premature failure. Follow all applicable shop safety procedures and machine tool manufacturer guidelines during insert changeover.
