Allied Machine 4T-06T204-M Indexable Drill Insert 4T06

Product Description

The ALLIED MACHINE AND ENGINEERING 4T-06T204-M is a solid carbide indexable drill insert designed for high-performance drilling in stainless steel and other demanding workpiece materials. Built to the 4T06 insert style with a proprietary shape, this insert seats in compatible Allied Machine indexable drill bodies and delivers consistent hole quality in right-hand cutting applications. A PVD coating process provides a hard, wear-resistant surface layer suited to the heat and work-hardening challenges common when machining stainless steel. The M25 material grade balances toughness and wear resistance for interrupted and continuous cuts in M-code workpiece materials.

This insert is intended for use in machine shops, production facilities, and field maintenance environments where indexable drilling tools are the standard approach. It is suited to CNC machining centers, lathes with live tooling, and dedicated drilling machines. The 4T06 series targets applications requiring a 2.80 mm hole diameter with controlled geometry. A 13-degree relief angle reduces cutting edge rubbing and supports efficient chip evacuation in stainless steel, nickel alloys, and similar materials that resist cutting.

Key Features

• Solid carbide construction with PVD coating for extended wear life in stainless steel
• Proprietary shape in the 4T06 insert style for use in Allied Machine compatible drill bodies
• Right-hand cutting direction with a 13-degree relief angle for reduced rubbing and clean chip flow
• M25 material grade provides toughness and wear resistance for M-code workpiece materials
• 0.40 mm corner radius for controlled edge geometry on small-diameter holes
• Manufactured under ISO 9001:2015 quality standards

Compatibility

Designed for use in Allied Machine and Engineering indexable drill bodies accepting the 4T06 insert style, Series 06, insert size 06T204. Verify body compatibility before ordering.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before seating or indexing the insert. Use the correct torx or hex key as specified by the drill body manufacturer to achieve proper clamping torque — do not overtighten or undertighten the clamping screw. Inspect the insert pocket for chips or burrs before seating a new insert to ensure correct seating and runout.
