Value Collection 720-4102 Square End Mill 1/8in Hss 4 Flute

Product Description

The VALUE COLLECTION 720-4102 is a double-end, four-flute square end mill manufactured from M2 high speed steel. It carries a 1/8 inch cutting diameter with a 3/8 inch length of cut and a matching 3/8 inch shank diameter. Overall length is 3-1/16 inches. The 30-degree right-hand spiral flute geometry promotes efficient chip evacuation in a wide range of ferrous and non-ferrous materials. The bright, uncoated finish makes wear monitoring straightforward during service life. This tool is centercutting, allowing plunge entry as well as conventional profiling and slotting operations. Machinists and tool-and-die professionals are the primary users.

This end mill suits CNC machining centers and manual milling machines where small-diameter, fine-detail work is required. The double-end design provides two usable cutting ends, extending tool life per unit. Typical applications include slot milling, profiling, and light pocketing in steel, aluminum, brass, and plastics. The fractional-inch 1/8 inch diameter makes it a common choice for engraving fixtures, prototype work, and precision component manufacturing where tight tolerances and clean square shoulders are required.

Key Features

• Double-end design yields two usable cutting ends per tool
• M2 high speed steel construction provides good toughness and wear resistance across a range of workpiece materials
• Centercutting geometry allows direct plunge entry without a pre-drilled hole
• 30-degree right-hand helix promotes efficient chip flow and reduces heat buildup at the cutting edge
• Bright, uncoated finish allows easy visual inspection of flute condition
• Four flutes deliver a finer surface finish compared to two-flute styles at equivalent feed rates

Compatibility

Designed for use in standard milling machine collets and end mill holders accepting a 3/8 inch shank diameter. Fits ER-style collet chucks, side-lock holders, and similar toolholding systems sized for 3/8 inch straight shanks on CNC and manual milling equipment.

Installation Notes

Installation is performed by a machinist or toolroom professional. Ensure the spindle is fully stopped and locked out before loading or removing the tool. Clean the collet bore and shank of any chips or coolant residue before seating to prevent runout. Confirm proper shank engagement depth in the holder per the toolholder manufacturer guidelines before beginning a cut.
