Allied 450H-17.5 Spade Drill Insert 17.5mm Cobalt AM200

Product Description

The ALLIED MACHINE AND ENGINEERING 450H-17.5 is a cobalt spade drill insert designed for high-performance drilling in demanding metalworking applications. It measures 17.5 mm in diameter with a 132-degree point angle and a thickness of 0.125 inches. The insert features an AM200 PVD coating applied over a cobalt substrate, providing enhanced wear resistance and thermal stability at the cutting edge. It is sized to Seat Size 0 and belongs to the GEN2 T-A series. Machinists and toolroom technicians install this insert into compatible T-A spade drill holders for precision-depth drilling in production and maintenance environments.

This insert is suited for drilling steel, stainless steel, cast iron, super-alloys, titanium, and hard materials, covering ISO material codes P, M, K, S, and H. It is commonly used in CNC machining centers, manual lathes, and drill presses where replaceable-insert spade tooling is preferred over solid twist drills. The GEN2 T-A platform is a widely adopted modular drilling system, and this insert slots directly into Seat Size 0 holders without regrinding or reconditioning. Typical applications include hole-making in structural components, flanges, and medium-to-hard alloy workpieces across aerospace, manufacturing, and general metalworking.

Key Features

• 17.5 mm cutting diameter with a 132-degree point angle for aggressive chip formation
• Cobalt substrate provides toughness and heat resistance in interrupted or hard-material cuts
• AM200 PVD coating reduces friction and extends tool life across multiple workpiece materials
• Seat Size 0 fits standard GEN2 T-A spade drill holders for quick insert changeover
• Covers ISO material codes P, M, K, S, and H — suitable for steel through hard materials
• Single-piece packaging with a minimum order quantity of 1 for maintenance and low-volume use

Compatibility

Designed for use with GEN2 T-A series Seat Size 0 spade drill holders from ALLIED MACHINE AND ENGINEERING.

Installation Notes

Installation is performed by machinists or toolroom technicians familiar with indexable spade drill tooling. Before changing the insert, ensure the machine spindle is fully stopped and the tool holder is secured or removed from the spindle. Seat the insert firmly into the holder pocket and torque the clamp screw per the holder manufacturer specification using a calibrated torque wrench. Inspect the seating surface for chips or debris before each insert change to maintain runout accuracy.
