Allied Machine 15YT-0013 Spade Drill Insert 13/32 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 15YT-0013 is a cobalt spade drill insert designed for high-performance hole-making in demanding machining applications. Part of the T-A series, this insert features a 132-degree point angle and a physical vapor deposition (PVD) TiN coating applied over a T15 cobalt substrate. The TiN coating reduces friction and extends cutting edge life across a range of workpiece materials. At 13/32 inch in diameter with a Seat Size Y designation, it mounts directly into compatible T-A series spade drill holders. Machinists and tooling specialists working in production or job-shop environments will find this insert suited for high-feed drilling operations.

This insert is engineered for cutting steel, stainless steel, cast iron, superalloys, and titanium — ISO material groups P, M, K, and S. It is well suited for CNC machining centers, lathes with live tooling, and dedicated drilling machines where consistent hole geometry and tool life are priorities. Applications span general manufacturing, aerospace component work, and heavy-equipment part production where cobalt tooling is specified over standard high-speed steel.

Key Features

• 13/32 inch cutting diameter with Seat Size Y for T-A series holder compatibility
• T15 cobalt substrate provides elevated heat and wear resistance versus M2 HSS
• PVD TiN coating reduces built-up edge and extends insert service life
• 132-degree point angle suits a broad range of workpiece materials including superalloys and titanium
• Fractional inch measurement system for straightforward sizing in standard tooling setups
• Sold individually, allowing single-insert replacement without purchasing a full set

Compatibility

Designed for use with T-A series spade drill holders that accept Seat Size Y inserts at 13/32 inch diameter. Confirm holder seat designation before ordering to ensure proper seating and clamping.

Installation Notes

Insert installation and replacement should be performed by a qualified machinist or tooling technician with the machine fully powered down and the spindle locked. Use the correct T-A series torx or hex key to seat the insert clamp screw to the holder manufacturer's specified procedure — do not overtighten by hand estimation. Inspect the holder seat for chips or debris before seating a new insert, as contamination in the pocket affects insert stability and hole accuracy. Follow all applicable shop safety procedures and machine guarding requirements during tooling changes.
