Value Collection 720-3165 Square End Mill 2 in 6 Flute Hss

Product Description

The VALUE COLLECTION 720-3165 is a single-end, 6-flute square end mill designed for milling operations in ferrous and non-ferrous metals. Built from M2 high speed steel with a bright/uncoated finish, it offers a 2-inch cutting diameter and a 2-inch length of cut, making it well suited for full-depth peripheral milling, slotting, and profiling passes. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces across the full length of cut. This tool is intended for use in manual mills and CNC machining centers by machinists and tooling professionals working to fractional inch standards.

This end mill is used in shop environments for face milling, side milling, and slotting in general-purpose metalworking applications. Its 1.25-inch shank diameter and 5.5-inch overall length suit it for standard R8, CAT, or BT toolholders sized for 1.25-inch shanks. The right-hand cutting and right-hand flute direction follow the standard convention for the majority of vertical milling setups. It is not center-cutting and is not designed for plunge entry. The regular length classification positions it as a general-purpose tool rather than a stub or extra-long reach variant.

Key Features

• 6-flute geometry increases contact and surface finish quality on finishing passes
• M2 high speed steel grade provides toughness and wear resistance for general metalworking
• 30-degree helix angle improves chip flow and reduces heat buildup during cuts
• Bright/uncoated finish allows easy visual inspection for wear
• Single-end design; not center-cutting - plunge entry is not supported
• Right-hand cut and right-hand spiral for standard vertical mill setups

Compatibility

Designed as a general-purpose replacement or production end mill for vertical mills and CNC machining centers accepting a 1.25-inch shank diameter in fractional inch tooling systems.

Installation Notes

Installation is performed by machinists using appropriate collets, end mill holders, or set-screw holders rated for a 1.25-inch shank. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Confirm holder runout is within acceptable tolerance before beginning a cut, as runout accelerates wear on HSS tooling. Follow your facility's lockout/tagout procedure before any tool change.
