Value Collection 724-0020 Roughing End Mill 1/4 in Cobalt

Product Description

The VALUE COLLECTION 724-0020 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel with a bright, uncoated finish, it delivers the heat and wear resistance needed for cutting ferrous and harder workpiece materials. The cutter measures 0.25 inches in diameter with a 0.625-inch length of cut and a 0.375-inch shank diameter. Three flutes and a right-hand cutting direction produce efficient chip evacuation while the center-cutting geometry allows plunge entry. This tool is suited for machinists and toolroom professionals running manual or CNC mills.

This roughing end mill is intended for use in general metalworking and machining applications where rapid stock removal is the priority. The 1/4-inch diameter profile makes it well suited for slotting, peripheral roughing, and pocketing operations in steel, stainless, cast iron, and similar alloys. The 2-7/16-inch overall length provides adequate reach for most standard setups without sacrificing rigidity. It installs in any standard end mill holder or collet chuck accepting a 3/8-inch shank.

Key Features

• M42 cobalt construction for elevated heat resistance during high-feed cuts
• 0.25-inch mill diameter with 0.625-inch length of cut for precise depth control
• 3-flute geometry promotes efficient chip clearance and reduces recutting
• Center-cutting design allows direct plunge entry without pre-drilling
• Right-hand cut and right-hand flute direction — compatible with standard spindle rotation
• Bright, uncoated finish — no coating to flake or delaminate in interrupted cuts

Compatibility

Designed as a standard single-end roughing end mill with a 3/8-inch shank, compatible with any end mill holder, collet chuck, or tool block sized for 3/8-inch shank tooling.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and lock out the spindle drive before changing tooling. Seat the shank fully into the collet or holder to the minimum insertion depth recommended by the holder manufacturer, and torque the retention hardware according to the holder specification. Inspect the cutting edges and shank for damage before mounting.
