Allied Machine 1021T-0102 Spade Drill Insert 1-1/16 in Hss Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 1021T-0102 is a spade drill insert designed for high-production drilling operations in metalworking applications. Built from High Speed Steel (HSS) with a Physical Vapor Deposition (PVD) TiN coating, this insert delivers improved wear resistance and extended tool life compared to uncoated HSS tooling. It measures 1-1/16 inches in diameter with a 130-degree point angle, making it well-suited for general-purpose drilling into steel, cast iron, and non-ferrous metals. The 7/8-inch height and 0.1875-inch thickness conform to Seat Size A geometry. Installation requires a compatible Seat Size A spade drill holder body.

This insert is intended for use in machine shop and manufacturing environments where spade drilling of ferrous and non-ferrous workpieces is a routine operation. It fits Seat Size A holder bodies and is appropriate for drilling steel, cast iron, and non-ferrous metals in CNC machining centers, lathes, and drill presses. Typical end users include machinists, toolroom technicians, and production floor operators handling through-hole and blind-hole drilling jobs that call for a 1-1/16-inch diameter cut.

Key Features

• High Speed Steel construction provides toughness across a broad range of workpiece materials
• TiN PVD coating reduces friction and extends cutting edge life
• 0.1875-inch insert thickness and 7/8-inch height conform to standard Seat Size A dimensions
• Rated for use in steel (P), cast iron (K), and non-ferrous metal (N) workpiece categories

Compatibility

Designed for use with Seat Size A spade drill holder bodies. Compatible workpiece materials include steel, cast iron, and non-ferrous metals as indicated by material codes P, K, and N.

Installation Notes

Insert installation should be performed with the machine fully powered down and the spindle locked. Seat the insert flush against the holder pocket and secure with the appropriate clamping screw using a calibrated torque driver per the holder manufacturer specifications. Inspect the insert seat for chips or debris before seating to prevent rocking or misalignment. Tool changes on CNC equipment should follow standard lockout/tagout procedures in accordance with applicable OSHA and facility safety protocols.
