Value Collection 724-5053 End Mill 5/16 in 4 Flute Cobalt Tin

Product Description

The VALUE COLLECTION 724-5053 is a roughing finishing end mill designed for material removal and finish cutting in a single tool. Built from M42 cobalt high-speed steel and coated with Titanium Nitride (TiN), it handles tough ferrous and non-ferrous materials at elevated cutting temperatures. The 5/16 inch diameter, 4-flute configuration delivers efficient chip evacuation and a smooth surface finish. With a 30-degree helix angle and right-hand flute direction, this end mill is suited for general-purpose milling operations. It is a single-end tool with a square end geometry and is not center-cutting, so it is not intended for plunge cuts.

This end mill is appropriate for use in vertical and horizontal milling machines, CNC machining centers, and manual mills in job shop, maintenance, and production environments. The Weldon flat shank provides positive engagement with set-screw tool holders, reducing slippage under heavy lateral loads. It is installed and used by machinists, toolmakers, and CNC operators working with steel alloys, stainless, and similar hard materials requiring a durable coated carbide-class tool.

Key Features

• M42 cobalt construction for elevated heat resistance in tough materials
• TiN coating reduces friction and extends tool life in ferrous applications
• 30-degree helix angle balances cutting pressure and chip flow
• Weldon flat shank ensures secure set-screw clamping in standard holders
• 4-flute square end geometry suitable for side milling, slotting, and finishing passes
• Right-hand cut and right-hand flute direction for standard spindle rotation

Compatibility

Designed for use with standard 3/8 inch Weldon flat tool holders compatible with vertical and horizontal milling machines and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Power down the spindle and confirm zero-energy state before changing tooling. Seat the Weldon flat against the set screw before tightening to the holder manufacturer's specified torque range. This tool is not center-cutting and must not be used for plunge milling; use a ramping or helical entry strategy when transitioning axially into a workpiece.
