Iscar 4836920 Indexable Drill Insert TPMX28RBG IC908

Product Description

The ISCAR 4836920 is a TPMX-style indexable drill insert designed for use in DEEPDRILL series indexable drilling systems. It is manufactured from solid carbide and finished with a PVD coating under the IC908 grade designation, which is engineered for thermal resistance and wear performance across a broad range of workpiece materials. The RBG chipbreaker geometry promotes efficient chip formation during deep-hole drilling operations. This insert is sold individually and is intended for installation by machinists, toolroom technicians, and CNC operators working in production or job-shop environments.

This insert is suited for both roughing and finishing drilling applications across universal workpiece material categories, including ferrous metals, cast iron, stainless and heat-resistant alloys, and non-ferrous materials. Its ISO 13399 compliance means tool data can be integrated directly into CAM systems and tool management platforms without manual entry. The DEEPDRILL platform is typically used in machining centers and CNC lathes for deep-hole drilling with indexable tooling rather than solid drills.

Key Features

• IC908 PVD-coated solid carbide grade for extended wear life across universal workpiece materials
• TPMX insert style with RBG chipbreaker geometry for controlled chip evacuation
• Insert size code 28 for compatibility with corresponding DEEPDRILL boring bodies
• Compliant with ISO 13399 for direct integration with CAM and tool management software
• Rated for H, K, M, P, and S ISO material group classifications

Compatibility

Designed for use with ISCAR DEEPDRILL series indexable drill bodies that accept TPMX insert style at insert size code 28. Confirm body seat specification before ordering.

Installation Notes

Indexable drill inserts should be seated and torqued using the manufacturer-specified insert screw and driver to avoid seat damage. Power down and lock out the spindle before changing inserts. Inspect the pocket seat for chips, burrs, or wear before installing a new insert, as a damaged seat will affect runout and insert life. Follow the toolholder manufacturer guidelines for recommended cutting parameters when commissioning a new insert grade.
