Value Collection 851-0125 Square End Mill 1/8 in 4 Flute Hss

Product Description

The VALUE COLLECTION 851-0125 is a double-end, square-profile end mill designed for general-purpose milling operations in machine shops and manufacturing environments. Built from high speed steel (HSS), it carries a bright, uncoated finish suited for a wide range of ferrous and non-ferrous materials. The cutter measures 0.125 inches in diameter with a 0.75-inch length of cut, a 0.1875-inch straight shank, and an overall length of 3.125 inches. Four spiral flutes with a 30-degree right-hand helix provide efficient chip evacuation and consistent surface finishes in slotting, profiling, and peripheral milling applications.

This end mill fits standard collet and tool holders accepting a 3/16-inch straight shank. Its long-series classification and double-end design make it a cost-effective choice for production shops running light-to-moderate material removal on milling machines and CNC machining centers. Typical applications include slot cutting, step milling, and contour work in aluminum, mild steel, plastics, and similar machinable materials where an HSS cutter is appropriate.

Key Features

• Double-end design extends usable tool life before replacement
• 4 right-hand spiral flutes at a 30-degree helix angle for efficient chip flow
• High speed steel construction provides toughness across a broad range of workpiece materials
• Bright, uncoated finish — ready for use as supplied or compatible with field coating processes
• Long-series length classification for added reach in deeper setups
• Straight shank fits standard collets and end mill holders without modification

Compatibility

Designed as a standard-shank replacement end mill compatible with collet chucks, end mill holders, and milling machine spindles accepting a 3/16-inch straight shank.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Secure the shank fully within the collet or holder to the manufacturer-recommended engagement depth before tightening. Inspect the collet and holder bore for wear or contamination prior to clamping. Always bring the spindle to a full stop before changing tooling, and verify runout with a dial indicator when tight tolerances are required.
