Value Collection 27759 Square End Mill 5/8 in 2 Flute Hss

Product Description

The VALUE COLLECTION 27759 is a double-end, two-flute square end mill designed for milling operations in steel, stainless steel, cast iron, and high-temperature alloys. Manufactured from M42 high speed steel with a bright/uncoated finish, it delivers reliable cutting performance across a broad range of ferrous materials. The cutter measures 5/8 inches in diameter with a 1-1/8 inch length of cut and a 4-1/2 inch overall length. A 30-degree right-hand spiral helix and right-hand cutting direction support efficient chip evacuation. Center-cutting capability allows plunge entry as well as conventional peripheral milling. This tool is installed and used by machinists and tool-and-die professionals in job shop and production environments.

This end mill is suited for slotting, profiling, and peripheral milling in manual and CNC machine tools. The double-end design provides two usable cutting ends, extending the service life of each tool before replacement. The 5/8 inch shank diameter fits standard ER collets, end mill holders, and Weldon-style holders commonly found in vertical milling machines and machining centers. It is appropriate for both roughing and light finishing passes in steel and related ferrous workpiece materials.

Key Features

• Double-end design provides two cutting ends per tool
• M42 high speed steel construction for durability in ferrous materials
• 30-degree right-hand helix promotes efficient chip evacuation
• Center-cutting geometry allows direct plunge entry
• Bright/uncoated finish suitable for general-purpose milling applications
• Right-hand cutting direction compatible with standard spindle rotation

Compatibility

Designed as a general-purpose replacement or stock end mill for use in vertical mills and CNC machining centers with standard 5/8 inch collet or end mill holder tooling. Rated for primary workpiece materials including steel, stainless steel, cast iron, and high-temperature alloys (material codes P, M, K, S).

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked before changing tooling. Secure the shank in a properly sized collet or end mill holder and verify runout before beginning a cut. Do not exceed the rated cutting parameters for the workpiece material and tool diameter.
