Allied Machine 152T-1.015-FB Spade Drill Insert Cobalt Tin 180pt

Product Description

The ALLIED MACHINE AND ENGINEERING 152T-1.015-FB is a cobalt spade drill insert designed for high-performance hole-making in demanding machining applications. This insert measures 1-1/64 inches in diameter with a 180-degree point angle and carries a TiN (titanium nitride) PVD coating to extend tool life and reduce built-up edge. At 0.1875 inches thick, it seats into a Size 2 T-A series spade drill holder. Machinists and tooling specialists install this insert when drilling through materials that generate high heat and wear on cutting edges.

The 152T-1.015-FB is built for production and job-shop environments where consistent hole quality matters across difficult workpiece materials. It is suited to drilling operations in steel, stainless steel, cast iron, super-alloys, and titanium — covering ISO material groups P, M, K, and S. Typical applications include general metalworking, aerospace component drilling, and heavy manufacturing where a replaceable insert design reduces tooling changeover time compared to solid drills.

Key Features

• 1-1/64 inch diameter cobalt insert for Size 2 T-A series spade drill holders
• 180-degree point angle for flat-bottom entry and reduced thrust force
• TiN PVD coating improves wear resistance and surface finish on the cutting edge
• Cobalt substrate provides elevated hardness and heat resistance versus standard HSS
• 0.1875 inch insert thickness for positive seating and repeatable positioning
• Rated for use in steel, stainless steel, cast iron, super-alloys, and titanium workpieces

Compatibility

Designed for use with Allied Machine T-A series spade drill holders accepting a Size 2 seat. Compatible workpiece materials include steel, stainless steel, cast iron, super-alloys, and titanium (ISO groups P, M, K, and S).

Installation Notes

Installation is performed by a machinist or tooling technician on a mill, lathe, or dedicated drilling machine. Ensure the spade drill holder and insert seat are clean and free of chips before seating the insert to prevent misalignment. Torque the insert fastener according to the holder manufacturer specifications — do not over-tighten. Verify spindle speed and feed rate are appropriate for the workpiece material and insert diameter before initiating the cut.
