Iscar 7000402 Cap Screw T15 Torx M4 Helimill Indexable

Product Description

The ISCAR 7000402 is a countersunk cap screw designed to secure indexable inserts in Helimill series milling toolholders. Using a T15 Torx drive and M4 thread, this screw provides reliable clamping force across insert-change cycles in demanding milling operations. The countersunk head profile keeps the screw flush with the toolholder pocket, preventing interference with chip flow and workpiece contact. At 9.30 millimeters in overall length, it is sized for the FDN-CM toolholder style. Machinists and toolroom technicians rely on OEM-specification hardware like this to maintain consistent insert seating and cutting geometry.

This cap screw is used in CNC milling applications where Helimill series toolholders are deployed for face milling, shoulder milling, and helical interpolation operations. It is specifically compatible with the ADKT 1505 PD-R insert and the FDN-CM toolholder style. Typical environments include production machining shops running ferrous and non-ferrous materials where insert indexing is performed frequently and fastener integrity directly affects surface finish and dimensional accuracy.

Key Features

• T15 Torx drive for positive bit engagement and reduced cam-out during insert changes
• M4 thread size matched to Helimill FDN-CM toolholder pocket specifications
• Countersunk head profile sits flush to avoid chip flow interference
• 9.30 mm overall length sized for correct insert clamping depth
• Compatible with ADKT 1505 PD-R indexable insert
• OEM-specification fastener maintains consistent insert seating and cutting geometry

Compatibility

Compatible with the ISCAR FDN-CM toolholder style in the Helimill series. Confirmed insert compatibility: ADKT 1505 PD-R. Intended for indexable milling applications requiring M4 cap screws with a T15 Torx drive and countersunk head.

Installation Notes

Installation is performed by toolroom technicians or machinists during scheduled insert indexing or replacement. Always power down and lock out the spindle before accessing the toolholder pocket. Use a calibrated T15 Torx driver or key and follow the toolholder manufacturer torque specification for M4 insert screws. Inspect the screw threads and pocket threads for wear or damage before reinstalling; damaged fasteners should be replaced rather than reused.
