Allied Machine 10264-0328 Spade Drill Insert 3-7/8 in Seat F

Product Description

The ALLIED MACHINE AND ENGINEERING 10264-0328 is a spade drill insert designed for high-performance hole-making in demanding metalworking applications. It measures 3-7/8 inches in diameter and 3-1/8 inches in height, with a thickness of 0.5 inches. The insert is manufactured from CPM-M4 powdered metal, a high-speed steel powder-metallurgy grade known for its wear resistance and toughness. A 130-degree point angle provides an aggressive cutting geometry suited to production drilling. The uncoated finish makes it a straightforward, cost-effective choice when coatings are not required by the application. Licensed machinists and toolroom technicians are the primary installers and users of this tooling.

This insert is intended for use in spade drill holder bodies with a Seat Size F designation. It is suited for drilling steel, cast iron, and non-ferrous metals in both manual and CNC machining environments. Typical applications include deep-hole roughing operations on lathes, machining centers, and drill presses where indexable tooling is preferred over solid twist drills. The CPM-M4 grade is well regarded for cutting abrasive ferrous materials and interrupted cuts common in production-volume environments.

Key Features

• 130-degree point angle optimized for steel and cast iron workpieces
• Seat Size F compatibility allows drop-in indexing in matching holder bodies
• Uncoated finish suited for applications where coolant lubricity replaces surface coating
• 0.5 inch insert thickness supports rigid seating and repeatable runout

Compatibility

Designed for use in spade drill holder bodies with a Seat Size F designation. Compatible primary workpiece materials include steel, cast iron, and non-ferrous metals as identified by material codes P, N, and K.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Before seating the insert, power down and lock out the spindle drive per site lockout/tagout procedures. Inspect the holder pocket and clamping screw for damage or debris before inserting. Do not exceed the holder manufacturer's recommended feed and speed parameters for the insert diameter and workpiece material combination.
