Allied Machine 152A-1.046 Spade Drill Insert 1-3/64 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 152A-1.046 is a cobalt spade drill insert designed for high-performance hole-making in demanding industrial drilling applications. Part of the T-A series, this insert features a 132-degree point angle and a TiAlN PVD coating that extends tool life by reducing heat buildup and wear at the cutting edge. The insert measures 0.1875 inches thick and fits a Seat Size 2 holder. It is sold individually per package and is intended for use by machinists and tool-and-die professionals working with production drilling equipment.

This insert is suited for drilling into steel, stainless steel, cast iron, super-alloys, and titanium. The T-A series spade drill system is a common choice in production machining environments where replaceable inserts reduce tooling cost and downtime compared to solid-shank drills. Typical applications include through-hole and blind-hole drilling on CNC machining centers, lathes, and dedicated drilling machines in job shops and manufacturing facilities.

Key Features

• 1-3/64 inch cutting diameter for precise bore sizing
• 132-degree point angle suited for a broad range of workpiece materials
• Cobalt substrate provides toughness and heat resistance at the cutting edge
• TiAlN PVD coating reduces wear and extends insert life in high-temperature cuts
• Seat Size 2 for use with compatible T-A series spade drill holders
• 0.1875 inch insert thickness for stable seating in the holder pocket

Compatibility

Designed for use with T-A series Seat Size 2 spade drill holders. Verify holder seat size and insert diameter against your holder manufacturer specifications before installation.

Installation Notes

Insert installation and replacement should be performed by a qualified machinist with the machine fully powered down and locked out per applicable safety procedures. Use the correct insert screw and torque driver recommended by the holder manufacturer to secure the insert in the pocket. Inspect the holder seat and clamping surfaces for chips or wear before seating a new insert. Follow shop safety guidelines and applicable OSHA machining standards during all tooling changes.
