Value Collection 27615 Square End Mill 3/4 in 4 Flute Hss

Product Description

The VALUE COLLECTION 27615 is a 4-flute, single-end square end mill designed for general-purpose milling operations in machine shops and production environments. Manufactured from M2 high speed steel with a bright/uncoated finish, it offers reliable performance across a range of ferrous and non-ferrous materials. The tool features a 3/4-inch cutting diameter, a 1-5/8-inch length of cut, and a 3-3/4-inch overall length. A 30-degree right-hand helix promotes efficient chip evacuation and smooth cutting action. Machinists and toolroom professionals are the primary installers and operators of this end mill.

This end mill is suited for slot milling, peripheral milling, and profiling operations on manual mills and CNC machining centers. The 3/4-inch shank diameter fits standard ER, CAT, BT, and R8 collet systems commonly found in vertical milling machines. The non-centercutting geometry makes it appropriate for side milling and slotting where a plunge entry is not required. Its spiral flute design and right-hand cutting direction are standard for conventional and climb milling passes.

Key Features

• 3/4-inch cutting diameter with matching 3/4-inch shank for direct collet mounting
• 1-5/8-inch length of cut suitable for moderate-depth slotting and profiling
• 4-flute spiral geometry for improved surface finish on ferrous materials
• 30-degree right-hand helix for efficient chip evacuation
• M2 high speed steel construction for toughness and wear resistance at moderate cutting speeds
• Bright/uncoated finish — compatible with cutting fluid application

Compatibility

Designed as a standard 3/4-inch shank square end mill compatible with collet chucks, end mill holders, and milling machine spindles accepting 3/4-inch tooling across vertical mills and CNC machining centers.

Installation Notes

Installation is performed by machinists using appropriate collet systems or end mill holders rated for the 3/4-inch shank diameter. Ensure the machine spindle is fully powered down and locked out before mounting or removing tooling. Confirm collet nut torque and tool runout with a dial indicator before beginning a cut. Follow shop-standard feeds and speeds for M2 HSS tooling based on workpiece material.
