Allied 151T-0030-FB Spade Drill Insert 15/16 in Cobalt Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 151T-0030-FB is a cobalt spade drill insert designed for high-performance hole-making in demanding machining applications. Measuring 15/16 inches in diameter with a 180-degree point angle, this insert delivers aggressive cutting geometry suited for production drilling. The TiN (titanium nitride) PVD coating reduces friction and extends tool life in abrasive materials. At 0.1563 inches thick, the insert seats into a Seat Size 1 holder from the T-A Series system. Machinists and toolroom professionals install this insert as a replaceable cutting element, keeping toolholder bodies in service while swapping worn edges quickly.

This insert is engineered for drilling steel, stainless steel, cast iron, super-alloys, and titanium — covering ISO material groups P, M, K, and S. It fits production and job-shop environments where interrupted cuts, varying material hardness, or high feed rates demand a wear-resistant insert with a rigid cobalt substrate. Typical applications include through-hole and blind-hole drilling on CNC machining centers, lathes with live tooling, and dedicated drill presses running T-A Series toolholders.

Key Features

• Cobalt insert material provides high heat resistance and toughness in hard or abrasive workpieces
• TiN PVD coating lowers friction and extends edge life across multiple material groups
• 180-degree point angle supports flat-bottomed entry and exit geometry
• 0.1563-inch insert thickness fits Seat Size 1 T-A Series toolholders precisely
• Compatible with steel, stainless steel, cast iron, super-alloys, and titanium workpiece materials
• Replaceable insert design reduces tooling cost by reusing the holder body

Compatibility

Designed for use with T-A Series Seat Size 1 spade drill toolholders. Compatible workpiece materials include steel, stainless steel, cast iron, super-alloys, and titanium (ISO groups P, M, K, S).

Installation Notes

Installation is performed by machinists or toolroom technicians. Always power down and lock out the machine spindle before changing inserts. Seat the insert fully against the holder pocket before torquing the clamping screw — an improperly seated insert can fracture under cutting loads. Follow the toolholder manufacturer's clamping torque guidelines and inspect the insert seat for chips or debris before each installation.
