Allied Machine 4T-11T306-M Indexable Drill Insert 4T11 Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 4T-11T306-M is a solid carbide indexable drill insert designed for high-performance drilling operations in stainless steel and other difficult-to-machine materials. Built to the 4T11 insert style with a proprietary shape, this insert features a PVD coating for improved wear resistance and extended tool life. It carries a 0.60 mm corner radius, a 13-degree relief angle, and an 11T306 insert size designation. Right-hand cutting geometry makes it suitable for conventional CNC drilling setups. At 0.02 pounds, the insert is compact and engineered for precision hole-making in demanding production environments.

This insert is intended for use in indexable drilling toolholders compatible with the 4T11 insert style and Series 11 designation. Its M25 material grade and PVD coating make it well-suited for stainless steel applications, where edge toughness and heat resistance are critical. The 4.60 mm hole diameter rating and 11.60 mm length make it appropriate for tight-tolerance drilling work in aerospace, medical, and general machining contexts where stainless steel is a primary workpiece material.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• PVD coating process extends cutting edge life and reduces built-up edge on stainless steel
• 0.60 mm corner radius reduces stress concentration at the cutting edge
• 13-degree relief angle provides clearance and reduces rubbing during drilling
• Right-hand cutting direction compatible with standard CNC drilling setups
• Manufactured to ISO 9001:2015 quality standards

Compatibility

Designed for use with indexable drill toolholders accepting the 4T11 insert style, Series 11, with an 11T306 insert size. Optimized for primary workpiece material code M, covering stainless steel grades.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before seating or replacing the insert. Use the appropriate torx or insert-retention hardware specified by the toolholder manufacturer. Inspect the pocket seating surface for chips or damage before indexing or installing a new insert to ensure proper seating and runout.
