Allied 15ZT-0015 Spade Drill Insert 15/32 in Cobalt Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 15ZT-0015 is a cobalt spade drill insert designed for high-performance drilling in demanding industrial applications. Part of the T-A Series, this insert measures 15/32 inch in diameter and features a 132-degree point angle optimized for penetrating hard and abrasion-resistant workpiece materials. The insert is manufactured from T15 material grade cobalt and receives a TiN (titanium nitride) coating applied via PVD process, which extends cutting-edge life and reduces friction during operation. At 0.0938 inch thickness, it seats in a Size Z holder. Machinists and tool-and-die professionals specify this insert for production drilling where tool longevity and hole quality matter.

The 15ZT-0015 is suited for drilling steel, stainless steel, cast iron, superalloys, and titanium — workpiece material codes P, M, K, and S. It fits T-A Series spade drill bodies using a Size Z seat. This insert is commonly used in CNC machining centers, manual drill presses, and production turning applications where a replaceable spade drill system is preferred over solid carbide or high-speed steel drill bits. It is sold individually and carries a minimum order quantity of one unit.

Key Features

• 15/32 inch diameter with 132-degree point angle for aggressive material penetration
• T15 cobalt construction provides heat and wear resistance in tough alloys
• TiN PVD coating reduces friction and extends cutting-edge service life
• Designed for T-A Series spade drill bodies, Size Z seat
• Compatible with steel, stainless steel, cast iron, superalloys, and titanium workpieces
• Fractional inch measurement system for straightforward sizing in standard tooling setups

Compatibility

Designed for use with T-A Series spade drill holders requiring a Size Z insert seat. Compatible with primary workpiece materials classified as P (steel), M (stainless steel), K (cast iron), and S (superalloys and titanium) per ISO material group designations.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel following the tool holder manufacturer's seating and torque guidance for T-A Series bodies. Power down and lock out the machine spindle before seating or removing the insert. Inspect the seat pocket for chips or damage prior to installation to ensure proper insert contact and prevent premature edge failure. Follow applicable shop safety protocols and manufacturer recommendations for coolant flow and feed-rate selection when drilling superalloys or titanium.
