Allied Machine 450H-14 Spade Drill Insert 14mm Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 450H-14 is a cobalt spade drill insert designed for high-performance drilling in demanding metalworking applications. This insert features a 132-degree point angle and an AM200 PVD coating that extends tool life by reducing heat buildup and wear at the cutting edge. At 0.125 inches thick and sized to Seat Size 0, it mounts into compatible GEN2 T-A spade drill bodies. Machinists and toolroom technicians working on production floors, job shops, or maintenance operations rely on this insert for consistent hole quality across a range of workpiece materials.

This insert is rated for use in steel, stainless steel, cast iron, super-alloys and titanium, and hard materials, covering ISO material groups P, M, K, S, and H. It belongs to the GEN2 T-A series, a widely used indexable spade drilling platform common in CNC machining centers and drill presses where through-coolant or flood-coolant delivery is standard practice. The 14 mm diameter targets precision bore work in automotive, aerospace, and general metalworking production environments.

Key Features

• 14 mm cutting diameter for precise metric bore sizing
• 132-degree point angle reduces thrust and improves chip formation on entry
• Cobalt substrate provides heat resistance in tough alloy and stainless drilling
• AM200 PVD coating extends edge life across P, M, K, S, and H material groups
• Seat Size 0 matches standard GEN2 T-A spade drill holder bodies
• 0.125-inch insert thickness for stable seating and repeatable indexing

Compatibility

Designed for use with GEN2 T-A series Seat Size 0 spade drill holder bodies. Compatible workpiece materials include steel, stainless steel, cast iron, super-alloys and titanium, and hard materials per ISO groups P, M, K, S, and H.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians following the drill body manufacturer's indexing procedure. Ensure the spindle is fully stopped and the machine is locked out before seating or removing the insert. Seat the insert firmly against the holder pocket and torque the clamping screw to the drill body manufacturer's specification. Inspect the seating pocket for chips or debris before each insert change to maintain runout accuracy.
