Allied Machine 4C11P-19 Spade Drill Insert 19mm Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 4C11P-19 is a solid carbide spade drill insert designed for precision hole-making in metalworking applications. Manufactured to GEN2 T-A series specifications, this insert features a 132-degree point angle and an AM300 PVD coating that extends tool life in demanding cutting conditions. The insert measures 19 mm in diameter and fits a Seat Size 1 holder. It carries a C1 (K35) material grade, making it well-suited for high-productivity drilling operations. Machinists and toolroom professionals install this insert as a direct-replacement blade in compatible T-A spade drill bodies.

This insert is intended for drilling steel and hard materials in industrial machining environments. The GEN2 T-A series is a common platform used in CNC turning centers, machining centers, and drill presses where replaceable-blade spade drilling is preferred over solid twist drills. It is a standard choice for production shops requiring repeatable hole geometry without regrinding tooling.

Key Features

• 19 mm cutting diameter with Seat Size 1 interface
• 132-degree point angle for controlled entry and chip formation
• Solid carbide construction, C1 (K35) material grade
• AM300 PVD coating for extended wear resistance in steel and hard materials
• GEN2 T-A series geometry for drop-in replacement in compatible holders

Compatibility

Designed for use in GEN2 T-A series Seat Size 1 spade drill holders. Primary workpiece materials are steel and hard materials (ISO material codes P and H). Confirm holder seat size before ordering.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machine before removing or seating the insert. Use the manufacturer-recommended torque driver and insert screw to secure the blade in the holder body — do not overtighten with general-purpose tools. Inspect the holder seat for chips or wear before installing a new insert to ensure proper seating and runout.
