Value Collection 720-2028 Square End Mill 9/32 in 2 Flute Hss

Product Description

The VALUE COLLECTION 720-2028 is a double-end, square-profile end mill manufactured from M2 high speed steel. It carries a 9/32-inch (0.2813-inch) cutting diameter with a 9/16-inch length of cut and mounts on a 3/8-inch shank. Overall length is 3.125 inches. The two-flute, 30-degree helix spiral design provides efficient chip evacuation and is center-cutting, allowing plunge entry into the workpiece. The bright, uncoated finish is standard for HSS tooling used across a wide range of common shop materials. Both ends are usable, extending tool life between changes.

This end mill is suited for milling, slotting, profiling, and light plunge operations in steel, stainless steel, cast iron, and high-temperature alloys. Its regular-length geometry fits standard milling setups in vertical knee mills, CNC machining centers, and manual knee mills where a 3/8-inch collet or end mill holder is available. The double-end configuration makes it a practical choice for shops looking to maximize use from a single tool before replacement. Right-hand cut and right-hand flute orientation is standard for conventional spindle rotation.

Key Features

• Double-end design — both ends are usable, doubling effective tool life
• Center-cutting capability allows direct plunge entry without pre-drilling
• 30-degree helix angle promotes smooth chip flow in ferrous materials
• M2 high speed steel construction for toughness across steel, stainless, cast iron, and high-temp alloys
• Bright uncoated finish — no coating buildup risk; easy to resharpen
• Right-hand cut, right-hand flute — compatible with standard CNC and manual spindle rotation

Compatibility

Designed for use in 3/8-inch collets, end mill holders, or Weldon-style holders on vertical milling machines and CNC machining centers. Primary workpiece materials include steel, stainless steel, cast iron, and high-temperature alloys.

Installation Notes

Installation requires a 3/8-inch collet or end mill holder; verify holder runout before use to prevent premature edge wear. Power down and lock out the machine spindle completely before inserting or removing the tool. Follow shop-standard feeds and speeds for M2 HSS tooling in the target material. Inspect both cutting ends for chipping or wear before each use.
