Value Collection 723-8683 Square End Mill 15mm 4 Flute Cobalt

Product Description

The VALUE COLLECTION 723-8683 is a cobalt square end mill designed for milling operations requiring durability and heat resistance. Built from M42 cobalt high-speed steel, this single-end tool features a 15 mm (0.5906 inch) cutting diameter and a 1-3/8 inch length of cut, making it well suited for slot milling, peripheral milling, and profiling cuts in ferrous and harder materials. The 4-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and a smooth finish. The bright, uncoated finish is appropriate for general-purpose applications where coating is not required. Licensed machinists and tool-and-die professionals are the primary users of this cutter.

This end mill is intended for use in conventional vertical and horizontal milling machines, CNC machining centers, and manual knee mills where a 1/2 inch straight shank is accepted. The regular-length geometry and 3-3/8 inch overall length provide rigidity for standard-depth cuts in steel, cast iron, alloy steels, and similar materials. The center-cutting design allows the tool to plunge directly into the workpiece as well as cut peripherally. Right-hand cutting direction matches standard spindle rotation on most production and job-shop equipment.

Key Features

• M42 cobalt HSS construction for improved red hardness and wear resistance versus standard M2 HSS
• 15 mm (0.5906 inch) cutting diameter with 4 flutes for balance between chip clearance and edge strength
• 30-degree helix angle promotes smooth cutting action and efficient chip evacuation
• Center-cutting geometry allows direct plunge entry into the workpiece
• Bright, uncoated finish suitable for general-purpose milling without coating-specific requirements
• Single-end, right-hand cut and flute direction compatible with standard spindle rotation

Compatibility

Designed for use in milling machines and machining centers that accept a 1/2 inch straight shank end mill holder, collet chuck, or matching ER collet. The 1/2 inch shank diameter (0.5000 inch) is a standard size across a wide range of toolholding systems used in job-shop and production environments.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholding specifications. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before inserting or removing the cutter. Set the tool to the recommended stickout length to maximize rigidity and minimize vibration during cutting. Do not exceed the machine spindle's rated speed or the recommended feed and speed parameters for the workpiece material.
