Allied Machine 10414-0108 Spade Drill Insert 1-1/4 in Seat a

Product Description

The ALLIED MACHINE AND ENGINEERING 10414-0108 is a spade drill insert designed for high-performance drilling in metalworking and machining applications. Manufactured from CPM-M4 powdered metal, this insert delivers the wear resistance and edge retention required for production drilling in steel, cast iron, and non-ferrous metals. It features a 180-degree point angle for flat-bottom entry and controlled chip formation. The insert is uncoated, making it suitable for applications where coating compatibility or regrinding is a priority. At 1-1/4 inches in diameter with a Seat Size A designation, it mounts into compatible spade drill holders used across CNC machining centers and manual drilling equipment. Installation is performed by qualified machinists or tooling technicians.

This insert is suited for production drilling operations in both job shop and manufacturing environments. Primary workpiece materials include steel, cast iron, and non-ferrous metals, covering a broad range of common machining tasks. The Seat Size A classification aligns the insert with the corresponding Allied Machine series A spade drill body. Applications range from through-hole and blind-hole drilling on machining centers to heavy-duty drill press operations where indexable tooling is preferred over solid drills. The 180-degree point angle makes it particularly effective for flat-bottom holes and work where standard conical-point geometry is not acceptable.

Key Features

• 1-1/4 inch diameter with Seat Size A for direct compatibility with Series A spade drill holders
• CPM-M4 powdered metal construction for high wear resistance and edge retention
• 180-degree point angle supports flat-bottom drilling and minimizes lead-in deviation
• Uncoated finish allows regrinding and suits applications where coatings are not required
• Rated for use in steel, cast iron, and non-ferrous metals across P, K, and N workpiece material categories
• Thickness of 0.1875 inches and height of 1-5/32 inches for precise seating in the holder body

Compatibility

Designed for use with Allied Machine and Engineering Series A spade drill holders. Compatible with primary workpiece materials classified as steel (P), cast iron (K), and non-ferrous metal (N).

Installation Notes

Spade drill insert replacement is performed by machinists or tooling technicians. Always power down and lock out the machine before indexing or replacing inserts. Use the correct torque wrench and insert screw specified for the holder to ensure proper seating and prevent insert movement under cutting loads. Inspect the holder seat for debris or damage before installing a new insert.
