Iscar 4818336 NPMT06LG IC908 Indexable Drill Insert

Product Description

The ISCAR 4818336 is an NPMT-style indexable drill insert designed for use in indexable drilling tools where consistent cutting performance and insert interchangeability are required. It carries the IC908 carbide grade with a TiAlN coating applied via PVD process, a combination that provides thermal resistance and wear protection across a broad range of workpiece materials. The LG chipbreaker geometry promotes controlled chip formation during drilling operations. This insert fits within the FINEBEAM series of indexable drill bodies and is handled by machinists and CNC operators in production and job-shop environments.

The 4818336 is rated for universal material application, covering ISO material groups H, K, M, P, and S. This makes it suitable for drilling carbon steels, stainless steels, cast irons, non-ferrous alloys, and superalloys without requiring a material-specific insert grade change. Typical applications include through-hole and blind-hole drilling on CNC machining centers and turning centers where FINEBEAM-compatible drill bodies are in use. Insert dimensions are 10 millimeters in length and 6.5 millimeters in width, corresponding to insert size code 06.

Key Features

• IC908 carbide grade with PVD-applied TiAlN coating for thermal and abrasion resistance
• NPMT insert style with LG chipbreaker for controlled chip formation in drilling
• Universal material rating covering ISO groups H, K, M, P, and S
• FINEBEAM series compatibility for use in matching ISCAR indexable drill bodies
• Conforms to ISO 13399 tool data standards for use in digital tool management systems
• Insert size code 06 with 10 mm length and 6.5 mm width for precise body fitment

Compatibility

Designed for use with ISCAR FINEBEAM series indexable drill bodies accepting NPMT insert style at size code 06. Confirm body specification and pocket geometry against ISCAR FINEBEAM tooling documentation before ordering.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist or CNC tooling technician following the drill body manufacturer torque and clamping specifications. Ensure the insert pocket is clean and free of chips or debris before seating the insert. Machine spindle must be fully stopped and locked out before any insert change. Follow applicable shop safety and machine guarding procedures when handling carbide inserts, as edges are sharp.
