Robbjack SR-4-060 Square End Mill 1/16 in 4 Flute Carbide

Product Description

The ROBBJACK SR-4-060 is a solid carbide square end mill designed for precision milling in demanding machining environments. Part of the SR-4 series, this tool features a 0.060-inch cutting diameter, a 0.180-inch length of cut, and a 1.500-inch overall length with a 0.125-inch straight cylindrical shank. With four spiral flutes and a 30-degree helix angle, it is engineered for efficient chip evacuation and stable cutting performance in small-diameter applications. Machinists and CNC operators working with tight-tolerance features and small-profile cuts will find this tool suited to that work.

This end mill is intended for use in CNC machining centers and manual mills where small-diameter, high-precision cuts are required. The centercutting geometry allows for plunge entry as well as conventional peripheral milling. Its right-hand cut and right-hand flute configuration is standard for most vertical and horizontal milling setups. The SR-4-060 is well-suited for slotting, profiling, and contouring operations in materials appropriate for the Tuffy material grade designation.

Key Features

• Solid carbide construction for rigidity and wear resistance in small-diameter tooling
• Four spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting design enables plunge milling and full-slot entry
• Right-hand cut, right-hand flute configuration for standard spindle rotation
• Straight cylindrical shank fits standard collet and end mill holder systems
• Uncoated finish; Tuffy material grade suited for specific workpiece materials per ROBBJACK guidelines

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for CNC and manual milling applications requiring a 0.125-inch shank diameter and 0.060-inch cutting diameter within the ROBBJACK SR-4 series.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the shank fully within a properly sized collet or end mill holder, ensuring minimum recommended shank engagement to prevent tool pullout. Verify spindle direction is set to right-hand rotation before engaging the cut. Handle carbide tooling with care to avoid chipping the cutting edges during setup and storage.
