Value Collection CSTM3187 Side Milling Cutter Cobalt

Product Description

The VALUE COLLECTION CSTM3187 is a staggered-tooth side milling cutter designed for horizontal milling operations on a wide range of materials. Built from M42 cobalt high-speed steel, it delivers the heat and wear resistance needed when cutting ferrous metals, non-ferrous metals, and non-metallic workpieces. The cutter measures 3 inches in diameter with a 3/16 inch (0.1875 inch) cutting width and mounts on a 1 inch arbor. Its 18-tooth staggered configuration reduces cutting forces and chatter, producing smoother finishes in slotting and side-milling applications. The uncoated finish allows for easy visual inspection of tool condition during service.

This cutter is suited for use on manual knee mills and CNC horizontal milling machines in job shops, maintenance departments, and production environments. Typical applications include slotting, grooving, and side-facing operations on steel, aluminum, brass, and plastics. The M42 cobalt grade makes it a practical choice when higher cutting temperatures are expected or when softer M2 tooling has shown premature wear. Installation requires a standard horizontal milling arbor with a 1 inch bore. Licensed machinists and tool-and-die technicians are the primary users of this cutter type.

• 3 inch cutter diameter with 3/16 inch cutting width for precise slot and groove work
• 1 inch arbor hole fits standard horizontal milling arbors
• 18 teeth provide a balance of chip clearance and finish quality
• Uncoated surface allows straightforward visual wear inspection
• Compatible with ferrous metals, non-ferrous metals, and non-metallic materials

Compatibility

Designed as an OEM-style replacement or direct-use side milling cutter for horizontal milling machines equipped with a 1 inch milling arbor. Suitable for cutting ferrous metals, non-ferrous metals, and non-metallic materials as stated by the manufacturer.

Installation Notes

Installation should be performed by a qualified machinist with the machine fully powered down and locked out per applicable lockout/tagout procedures. Mount the cutter securely on a clean, burr-free 1 inch milling arbor and confirm all arbor nuts and collars are properly tightened before engaging the spindle. Inspect the cutter for chips or cracks before each use and never exceed the machine spindle speed recommended for the cutter diameter and material being cut.
