Iscar 7002853 Clamping Key T10 Torx Indexable Milling

Product Description

The ISCAR 7002853 is a T10 Torx clamping key designed to secure indexable inserts in compatible milling toolholders. This hardware component transmits the clamping force needed to lock indexable inserts firmly in place during milling operations, preventing movement under cutting loads. At 0.227 pounds and measuring 7.48 inches in length and 1.97 inches in width, the key is a compact but critical piece of toolholder hardware. It is installed by ISCAR-authorized tooling setups and maintained by toolroom technicians and machinists working with the Multimaster, FlexFit, and Mini TangSlot series platforms.

This clamping key is intended for milling applications using ISCAR indexable milling heads and compatible toolholders across several series. It fits a wide range of Multimaster-series toolholder styles, making it suitable for use on machining centers and milling machines in both production and job-shop environments. The T10 Torx drive interface provides positive engagement during tightening and reduces the risk of drive recess damage compared to hex key designs.

Installation Notes

This clamping key is installed by toolroom technicians or machinists during indexable insert changes or toolholder maintenance. Before servicing, ensure the machine spindle is fully stopped and all power to the machining center is locked out per applicable OSHA lockout/tagout procedures. Use a calibrated T10 Torx driver or wrench to seat the key properly — avoid improvised drive tools that can damage the recess. Inspect the key for wear or deformation at regular service intervals and replace if the drive interface shows signs of rounding.
