Allied Machine 152A-0107 Spade Drill Insert 1-7/32 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 152A-0107 is a cobalt spade drill insert engineered for high-performance hole-making in demanding metalworking applications. Part of the T-A series, this insert measures 1-7/32 inches in diameter and seats in a Size 2 holder. It features a 132-degree point angle and a PVD-applied TiAlN coating, which reduces heat buildup and extends tool life when drilling through tough materials. At 0.1875 inches thick, the insert delivers structural rigidity under heavy feed rates. Machinists and tool-and-die professionals working in job shops, aerospace, and general manufacturing will find this insert suited to high-volume drilling operations.

The 152A-0107 is designed for use in T-A series spade drill holders with a Size 2 seat. It performs across a broad range of primary workpiece materials including steel, stainless steel, cast iron, super-alloys, and titanium. This makes it a versatile choice for production drilling on CNC machining centers, lathes with live tooling, and dedicated drill presses where consistent hole diameter and finish are required across multiple material types.

Key Features

• 1-7/32 inches cutting diameter in T-A series Size 2 seat configuration
• 132-degree point angle for effective chip splitting and reduced thrust force
• Cobalt substrate provides toughness and heat resistance in interrupted or hard-material cuts
• PVD TiAlN coating extends insert life and maintains cutting edge integrity at elevated temperatures
• 0.1875 inches insert thickness supports rigidity under aggressive feed conditions
• Rated for steel, stainless steel, cast iron, super-alloys, and titanium workpieces

Compatibility

Designed for use with T-A series spade drill holders accepting a Size 2 seat. Compatible with primary workpiece material codes P (steel), M (stainless steel), K (cast iron), and S (super-alloys and titanium) as classified in standard ISO material group designations.

Installation Notes

Spade drill insert installation and replacement should be performed by a qualified machinist with the machine fully stopped and locked out per established lockout/tagout procedures. Inspect the holder seat for wear, debris, or damage before seating the insert, as an unclean seat can cause insert movement and premature failure. Use the manufacturer-specified torque tool or wrench for the holder clamping screw — do not overtighten by hand or with improvised tools. Confirm insert seating and runout before returning the spindle to operation.
