Value Collection 723-9100 Square End Mill 10mm 2 Flute Cobalt

Product Description

The VALUE COLLECTION 723-9100 is a cobalt square end mill designed for general-purpose milling of ferrous and high-temperature materials. Built from M42 cobalt high-speed steel, it delivers increased heat and wear resistance compared to standard HSS tooling. The single-end configuration features 2 spiral flutes with a 30-degree right-hand helix, producing efficient chip evacuation and clean shoulder cuts. At 10 mm (0.3937 inches) in diameter with a 13/16-inch (0.8125 inches) length of cut, this tool is sized for slotting, profiling, and peripheral milling operations in production and job-shop environments. It is centercutting, allowing direct plunge entry into workpieces.

This end mill is suited for machining steel, stainless steel, cast iron, and high-temperature alloys in both manual and CNC milling applications. The bright uncoated finish makes it straightforward to regrind and inspect for wear. With a 3/8-inch shank diameter and 2-1/2-inch overall length in a regular-length configuration, it fits standard ER and side-lock toolholders commonly used in vertical machining centers, knee mills, and toolroom equipment. Machinists and tool-and-die professionals will find it appropriate for moderate-depth cuts in tough materials where cobalt tooling outperforms standard M2 HSS.

Key Features

• M42 cobalt construction for improved heat resistance and tool life in ferrous materials
• 30-degree right-hand helix with 2 spiral flutes for efficient chip evacuation
• Centercutting geometry allows direct plunge milling without pre-drilling
• Bright uncoated finish — easy to inspect for wear and regrind
• Single-end design, regular length — 2-1/2 inches OAL with 13/16-inch length of cut
• Right-hand cutting direction compatible with standard spindle rotation

Compatibility

Compatible with workpiece materials including steel, stainless steel, cast iron, and high-temperature alloys (ISO material groups P, M, K, and S). Fits standard toolholders accepting a 3/8-inch shank diameter.

Installation Notes

Install in a clean, properly sized collet or side-lock toolholder and verify runout before cutting. Secure shank engagement depth should follow toolholder manufacturer guidelines to minimize deflection. Always bring spindle to a full stop and confirm machine is locked out before changing or inspecting tooling. Follow shop-standard feeds, speeds, and depth-of-cut parameters appropriate for cobalt HSS end mills in the target workpiece material.
