Iscar 7002791 Cap Screw T20 Torx M5 Helialu Milling

Product Description

The ISCAR 7002791 is a countersunk-head cap screw designed to secure indexable inserts in milling toolholders. It uses a T20 Torx drive and M5 thread, providing reliable clamping torque without stripping or cam-out during insert changes. At 10.40 mm overall length, the screw seats flush in the insert pocket, keeping the cutting geometry consistent. This fastener is part of the Helialu series and is intended for use by machinists and toolroom technicians who maintain indexable milling tool assemblies in production or job-shop environments.

This cap screw is compatible with HM90 and SM style toolholders used in indexable milling applications. It is driven with BLD T20/M7 or BLD T20/S7 key drivers and is rated for insert-securing duty in Helialu series milling cutters. Typical installations include face mills, shoulder mills, and helical milling bodies that accept M5 countersunk insert screws. This screw is sold in multiples of 5, making it practical to stock as a maintenance consumable for shops running high-volume indexable tooling programs.

Compatibility

Compatible with HM90 and SM style toolholders. Confirmed compatible inserts include HM90 APCR 160502R-P, HM90 APCR 160504R-P, HM90 APCR 160505R-P, HM90 APCR 160508R-P, and HM90 APCR 160516R-P. Driven with BLD T20/M7 or BLD T20/S7 key drivers.

Installation Notes

Installation is performed by machinists or toolroom technicians during indexable insert changes or cutter maintenance. Always de-energize spindle power and confirm the machine is in a safe lockout state before accessing the cutter body. Use only the specified T20 Torx key driver to avoid fastener damage. Do not reuse screws that show signs of thread deformation or head wear, as compromised fasteners can allow insert movement under cutting loads.
