Iscar 7000381 Cap Screw T9 Torx M3 Indexable Drilling

Product Description

The ISCAR 7000381 is a countersunk cap screw designed to secure indexable inserts in ISCAR DR-3D-N drilling toolholders. It uses a T9 Torx drive and M3 thread for precise torque application during insert clamping. At 6.50 mm overall length and weighing approximately 0.05 pounds, this screw is engineered to the close tolerances required for indexable tooling systems. Licensed machinists, tool crib technicians, and CNC setup personnel use this fastener as a consumable replacement component when servicing or rebuilding indexable drilling assemblies. Keeping spare screws on hand prevents downtime during insert changes on the shop floor.

This cap screw is intended for use in indexable drilling applications where the DR-3D-N toolholder style is specified. It seats flush via its countersunk head geometry, which is standard for insert-clamping hardware in indexable drill bodies. The screw is sold individually per package, with a minimum order quantity of 5 units, making it suitable for stocking alongside insert inventories on high-volume drilling operations in production machining environments.

Key Features

• T9 Torx drive for controlled, precise insert-clamping torque
• M3 thread size matches DR-3D-N toolholder insert screw seat
• Countersunk head seats flush within the insert pocket
• 6.50 mm overall length engineered for indexable drill body geometry
• Consumable replacement fastener for indexable insert service and rebuild

Compatibility

Designed for use with ISCAR DR-3D-N style toolholders and compatible with indexable insert hardware requiring an M3 thread countersunk cap screw with T9 Torx drive.

Installation Notes

Installation should be performed by a qualified machinist or tool crib technician familiar with indexable tooling assembly procedures. Always power down and lock out the machine before servicing toolholders or changing inserts. Use a calibrated T9 Torx driver or torque wrench with the correct bit to seat the screw without stripping the drive or over-stressing the thread. Do not substitute screws of differing thread pitch, drive type, or head geometry, as improper fasteners can cause insert movement or ejection during cutting.
