Allied Machine 7C115P-15.25 Spade Drill Insert 15.25mm Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 7C115P-15.25 is a carbide spade drill insert designed for high-performance drilling in steel and hard materials. Part of the GEN3SYS XT series, this insert features a 140-degree point angle that promotes self-centering entry and reduces thrust load on the spindle. The AM300 PVD coating improves wear resistance and heat dissipation, extending tool life in demanding production environments. Seat Size 15 ensures proper seating in compatible spade drill holders. This insert is specified and installed by machinists, tooling engineers, and CNC operators in metalworking shops running high-volume drilling operations.

This insert is suited for drilling operations in steel and hard workpiece materials in both job shop and production settings. The GEN3SYS XT series is engineered for use in CNC machining centers, lathes with live tooling, and dedicated drilling machines. It is dimensioned in metric measurements, making it a natural fit for metric tooling setups. The 15.25 mm diameter suits applications requiring precision bore sizing without a secondary reaming operation in appropriate materials and conditions.

Key Features

• 15.25 mm cutting diameter for precision bore sizing
• 140-degree point angle reduces thrust and improves self-centering
• Carbide substrate, Manufacturer Grade C1 (K35), for high hardness and wear resistance
• AM300 PVD coating enhances tool life in steel and hard material applications
• GEN3SYS XT series design for consistent insert-to-holder repeatability
• Seat Size 15 for direct replacement in compatible GEN3SYS XT holders

Compatibility

Designed for use with GEN3SYS XT series spade drill holders accepting Seat Size 15 inserts. Intended for primary workpiece materials classified as Steel and Hard Material (material codes P and H).

Installation Notes

Installation of spade drill inserts should be performed by a qualified machinist or tooling technician with the machine powered down and locked out per applicable safety procedures. Seat and insert mating surfaces should be clean and free of chips or debris before seating the insert. Follow the holder manufacturer torque specifications for the clamping screw — do not over-torque, as this can crack the carbide substrate. Verify insert seating and runout before returning the spindle to service.
