Allied Machine 15YA-11 Spade Drill Insert 11mm Cobalt Tialn

Product Description

The ALLIED MACHINE AND ENGINEERING 15YA-11 is a cobalt spade drill insert designed for high-performance hole-making in demanding metalworking applications. Built to T-A series specifications, this insert features a 132-degree point angle and a TiAlN (titanium aluminum nitride) PVD coating that extends tool life under high heat and friction. The seat size Y designation ensures direct fitment with compatible T-A series spade drill holders. At 0.0938 inches thick and 11 mm in diameter, this insert suits precision drilling operations where consistent geometry and coating integrity are critical. Machinists and tooling specialists working in production or job-shop environments will find this insert well-suited to high-volume drilling cycles.

This insert is intended for use in steel, stainless steel, cast iron, super-alloys, and titanium workpieces, covering ISO material groups P, M, K, and S. It fits standard T-A series spade drill holder bodies that accept seat size Y inserts. Typical applications include through-hole and blind-hole drilling on CNC machining centers and drill presses where insert-style tooling is preferred over solid-shank drills for cost efficiency and repeatability. This insert is sold individually but carries a minimum order quantity of 2 units.

Key Features

• 11 mm cutting diameter with seat size Y for T-A series holder compatibility
• 132-degree point angle optimized for a wide range of workpiece materials
• Cobalt substrate provides toughness and heat resistance in interrupted cuts
• TiAlN PVD coating reduces built-up edge and extends tool life at elevated cutting speeds
• Rated for steel, stainless steel, cast iron, super-alloys, and titanium
• Insert-style design allows fast changeover without removing the holder from the machine

Compatibility

Designed for use with T-A series spade drill holder bodies accepting a seat size Y insert. Compatible with primary workpiece material groups P (steel), M (stainless steel), K (cast iron), and S (super-alloys and titanium).

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool holder is secured before seating or removing the insert. Verify the holder pocket and clamping screw are clean and free of chips before installing the new insert. Follow the tool manufacturer's clamping torque guidelines for T-A series holders to avoid insert movement or premature failure during cutting.
