Allied Machine 7C114P-.578 Spade Drill Insert 37/64 in

Product Description

The ALLIED MACHINE AND ENGINEERING 7C114P-.578 is a solid carbide spade drill insert designed for high-performance drilling in steel and hard materials. Built to GEN3SYS XT series standards, this insert features a 140-degree point angle and an AM300 PVD coating for extended tool life and heat resistance. It fits Seat Size 14 holders and is intended for use by machinists and toolroom professionals in production drilling applications. The C1 (K35) material grade provides a balance of hardness and toughness suited for aggressive cutting conditions.

This insert is used in CNC machining centers, drill presses, and manual lathes where spade drilling of steel and hard workpiece materials is required. The GEN3SYS XT platform is designed for high-penetration-rate drilling in industrial and manufacturing environments. Its compact geometry suits applications where a replaceable carbide insert is preferred over a solid twist drill for cost efficiency and consistency across multiple drilling cycles.

Key Features

• 37/64 inch diameter for precise hole sizing without regrinding
• Solid carbide construction with C1 (K35) material grade for hardness and wear resistance
• AM300 PVD coating extends cutting life in steel and hard materials
• 140-degree point angle reduces thrust and improves chip formation on entry
• Seat Size 14 compatibility integrates with GEN3SYS XT spade drill bodies
• Lightweight at 0.005 pounds, minimizing holder imbalance at high spindle speeds

Compatibility

Designed for use with GEN3SYS XT series Seat Size 14 spade drill holders. Intended for primary workpiece materials classified as Steel (P) and Hard Material (H) per ISO material group designations.

Installation Notes

Installation is performed by toolroom technicians or CNC setup personnel. Ensure the drill body and holder are fully de-energized and the spindle is locked before seating or removing the insert. Use the appropriate torx or hex key specified by the holder manufacturer to secure the insert to the correct clamp torque — do not overtighten. Inspect the seat for chips or debris before installation to ensure proper seating and runout control.
