Allied Machine 451H-0023 Spade Drill Insert 23/32 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 451H-0023 is a cobalt spade drill insert designed for high-performance hole-making operations in demanding machining environments. It measures 23/32 inches in diameter and features a 132-degree point angle for accurate entry and reduced thrust. The insert carries an AM200 PVD coating that extends tool life when cutting abrasive or high-strength workpiece materials. Thickness is 0.1563 inches. This insert fits Seat Size 1 toolholders in the GEN2 T-A spade drill system. It is installed by machining professionals on CNC and manual drill presses, lathes, and machining centers.

The 451H-0023 is suited for production and job-shop environments where a range of workpiece materials is encountered. Rated primary workpiece materials include Steel, Stainless Steel, Cast Iron, Super-alloys and Titanium, and Hard Materials, corresponding to ISO material codes P, M, K, S, and H. It is a single-insert replacement component sold individually and is intended for use wherever a GEN2 T-A Seat Size 1 spade drill body is already in service.

Key Features

• 23/32 inch cutting diameter in standard GEN2 T-A Seat Size 1 form factor
• Cobalt substrate provides elevated heat and wear resistance versus standard HSS
• AM200 PVD coating extends insert life on steel, stainless, cast iron, super-alloys, titanium, and hard materials
• 132-degree point angle promotes self-centering entry and minimizes exit burr
• 0.1563 inch insert thickness for consistent seating in compatible toolholders
• Sold as individual insert for targeted replacement without purchasing a full drill assembly

Compatibility

Designed for use with GEN2 T-A spade drill bodies accepting a Seat Size 1 insert. Compatible primary workpiece materials are Steel, Stainless Steel, Cast Iron, Super-alloys and Titanium, and Hard Materials (ISO codes P, M, K, S, H).

Installation Notes

Insert replacement should be performed by a qualified machinist with the spindle fully stopped and the machine locked out per applicable safety procedures. Seat surfaces on the drill body should be inspected and cleaned before seating the new insert to ensure proper contact and accurate runout. Use the torque wrench and insert screw specified by ALLIED MACHINE AND ENGINEERING for the GEN2 T-A system — do not over-torque the clamping screw. Confirm insert is fully seated and secure before resuming cutting operations.
