Value Collection 27608 Square End Mill 9/16 in 4 Flute Hss

Product Description

The VALUE COLLECTION 27608 is a single-end square end mill designed for general-purpose milling operations in machine shops and production environments. Built from M2 high speed steel with a bright/uncoated finish, it offers solid performance across a range of ferrous and non-ferrous materials. The cutter measures 9/16 inches in diameter with a 1-3/8 inches length of cut and a 3-3/8 inches overall length. A 30-degree right-hand spiral helix and four flutes support efficient chip evacuation during peripheral and slot milling. Installation and operation are handled by machinists and CNC operators working with vertical milling machines, knee mills, and machining centers.

This end mill is suited for slot milling, profiling, and peripheral milling in both manual and CNC setups. The 1/2 inches shank diameter fits standard ER collet chucks, end mill holders, and Weldon-style tool holders commonly found in job shop and production environments. The non-centercutting geometry means it is optimized for side milling and peripheral passes rather than direct plunge entry. Applications include steel, cast iron, aluminum, and similar machinable materials at moderate cutting speeds appropriate for HSS tooling.

Key Features

• M2 high speed steel construction provides toughness and wear resistance across a broad range of workpiece materials
• Four-flute design balances chip clearance with surface finish capability
• 30-degree right-hand helix promotes smooth cutting action and efficient chip flow
• Bright/uncoated finish suitable for use with cutting fluids on ferrous and non-ferrous materials
• Single-end configuration with a 1/2 inches shank diameter for compatibility with standard tool holders
• Non-centercutting geometry optimized for side milling and profiling operations

Compatibility

Designed as a standard replacement or stock end mill for use in any milling setup accepting a 1/2 inches shank diameter tool holder, including ER collet systems and Weldon-style end mill holders.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully and evenly in the tool holder and torque the set screw or collet nut to the holder manufacturer's specification. Verify runout with a dial indicator before beginning the cut, as excessive runout accelerates tool wear and degrades surface finish.
