Allied Machine and Engineering 4T-070305-M Indexable Drill Insert

Product Description

The ALLIED MACHINE AND ENGINEERING 4T-070305-M is a solid carbide indexable drill insert designed for use in indexable drill tooling systems. Manufactured to the 4T07 insert style, this insert features a proprietary shape with a 0.5 mm corner radius and a 13-degree relief angle. The cutting edge is PVD-coated with an AM485 finish, a treatment that improves wear resistance and edge retention during demanding drilling operations. At 8.00 mm in length and weighing approximately 0.01 pounds, this insert is a compact, precision-ground component intended for machine tool operators and CNC machinists working with stainless steel workpiece materials.

This insert is rated for primary use in stainless steel applications, corresponding to ISO material group M, and carries a material grade designation of M25. It fits the 07 series insert size code (size 070305) and is suited for through-hole and blind-hole drilling operations on machining centers and CNC lathes where controlled chip formation and edge stability are critical. The insert is sold individually with a minimum order quantity of 10 units, making it appropriate for shop stock replenishment or toolcrib management.

Key Features

• Solid carbide construction with PVD-applied AM485 coating for extended tool life in stainless steel
• Proprietary insert shape engineered for the 4T07 indexable drill system
• 0.5 mm corner radius for controlled edge engagement and reduced chipping
• 13-degree relief angle to minimize rubbing and heat buildup at the cutting edge
• ISO 9001:2015 certified manufacturing process
• Insert size code 070305, series 07, for precise seat fit and repeatability

Compatibility

Designed for use with indexable drill bodies accepting the 4T07 insert style, series 07, insert size 070305. Intended for stainless steel workpiece materials (ISO material group M, grade M25). Confirm insert seat geometry and clamping requirements with the drill body manufacturer before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tool setup technicians. Power down and lock out the machine spindle before seating or indexing any insert. Use the correct torque wrench and manufacturer-specified clamping hardware to secure the insert in the drill body pocket — do not overtighten or substitute fasteners. Inspect the insert seat for chips or debris before installation, as contamination in the pocket affects insert seating and runout.
