Allied Machine 152N-0109 Spade Drill Insert 1-9/32 in Cobalt Ticn

Product Description

The ALLIED MACHINE AND ENGINEERING 152N-0109 is a spade drill insert designed for high-performance hole-making in demanding machining applications. Built from cobalt high-speed steel and finished with a TiCN (titanium carbonitride) PVD coating, this insert delivers improved wear resistance and thermal stability compared to uncoated alternatives. It features a 132-degree point angle optimized for accurate entry and reduced thrust in tough workpiece materials. At 0.1875 inches thick with a 1-9/32 inches cutting diameter, it fits T-A Series seat size 2 holders. Machinists and tool-crib professionals working in production environments or job shops install this insert as a replaceable cutting element in compatible spade drill bodies.

This insert is suited for drilling steel, stainless steel, cast iron, super-alloys, and titanium. ISO material classification codes P, M, K, and S cover this range, making it a versatile choice for shops working across multiple workpiece materials. Typical applications include through-hole and blind-hole drilling on CNC machining centers, lathes with live tooling, and manual drill presses where T-A Series tooling is already in use. The TiCN coating is particularly beneficial when cutting stainless steel and super-alloys where heat buildup and edge wear are primary concerns.

Key Features

• 1-9/32 inches cutting diameter in T-A Series seat size 2 configuration
• Cobalt substrate provides toughness and heat resistance beyond standard HSS
• TiCN PVD coating reduces friction and extends edge life in abrasive materials
• 132-degree point angle supports clean entry and reduced axial thrust
• Compatible workpiece materials span P, M, K, and S ISO classifications including steel, stainless, cast iron, super-alloys, and titanium
• Replaceable insert design minimizes downtime versus regrinding solid drills

Compatibility

Designed for use with T-A Series spade drill bodies accepting seat size 2 inserts. Verify holder seat size and series designation before installation to confirm fit.

Installation Notes

Installation is performed by qualified machinists following standard toolroom procedures. Secure the insert fully into the holder pocket and torque the clamp screw per the holder manufacturer's specification before use. Power down and lock out the machine spindle before changing inserts. Do not run the insert beyond its rated workpiece material range, as doing so can cause premature edge failure or insert fracture.
