Iscar 4300515 Replaceable Tip Milling Shank 40mm Drive

Product Description

The ISCAR 4300515 is a replaceable-tip milling shank in the Self-Grip series, designed for secure tool engagement in CNC milling operations. The shank features a straight, 40 mm drive shank diameter (1.5748 inches) with a Weldon flat for positive rotational drive and anti-pullout retention. With an 80 mm neck diameter and a compact 60 mm overall length (2.3622 inches), this toolholder is built for rigidity in high-feed and shoulder milling applications. It accepts GM-DG, SGSF, and TGSF style milling tips. Installation is performed by machinists and CNC setup technicians working with modular tooling systems.

This shank is suited for use in machining centers requiring a modular, interchangeable-tip toolholding solution. The Self-Grip locking mechanism provides consistent radial and axial positioning of the cutting tip without coolant-through capability, making it appropriate for dry or external coolant milling setups. The 40 mm maximum cutting diameter aligns the shank with mid-range milling operations in both ferrous and non-ferrous materials across job shop and production environments.

Key Features

• Self-Grip series modular interface for fast, repeatable tip changes without full tool replacement
• Weldon flat on straight shank provides positive anti-rotation drive retention
• Compatible with GM-DG, SGSF, and TGSF style replaceable milling tips
• Compact 60 mm overall length (2.3622 inches) reduces overhang in tight-clearance setups
• 40 mm maximum cutting diameter with 80 mm neck diameter for stable tip support
• No coolant-through design simplifies use in external or dry coolant applications

Compatibility

Designed for use with ISCAR Self-Grip series replaceable milling tips in GM-DG, SGSF, and TGSF styles. Intended for machine spindles and toolholders accepting a 40 mm straight shank with Weldon flat drive interface.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully powered down and locked out before mounting or removing the shank. Seat the Weldon flat drive screw to the toolholder manufacturer's specified procedure to prevent axial pullout during cutting. Verify tip style compatibility before seating the replaceable milling tip into the Self-Grip interface.
