Value Collection 720-9090 Square End Mill 2 Flute Hss

Product Description

The VALUE COLLECTION 720-9090 is a single-end, two-flute square end mill manufactured from M2 high speed steel (HSS). Designed for general-purpose milling operations, it features a 0.3543-inch cutting diameter, a 9/16-inch length of cut, and a 3/8-inch straight shank. The bright, uncoated finish reflects the base M2 steel with no additional coating treatment. At 2-5/16 inches overall length, this end mill suits standard toolholders and milling chucks in both manual and CNC machining environments. The right-hand cut and right-hand spiral flute geometry with a 30-degree helix angle promotes efficient chip evacuation and stable cutting performance across a range of workpiece materials.

This end mill is suited for slotting, profiling, and peripheral milling operations on steel, stainless steel, cast iron, and aluminum and non-ferrous materials. The centercutting design allows for plunge entry as well as standard side milling cuts. It is a practical general-purpose choice for job shop work, toolroom applications, and maintenance machining where an uncoated HSS tool is preferred over carbide or coated alternatives.

Key Features

• M2 high speed steel construction for toughness across a broad range of workpiece materials
• 0.3543-inch (9.00 mm) cutting diameter with a 9/16-inch length of cut
• Centercutting geometry permits direct plunge entry without a pre-drilled pilot hole
• 30-degree helix angle with right-hand cut and right-hand spiral flute for efficient chip flow
• Bright/uncoated finish - suitable for applications where coating is not required or not preferred
• Single-end design; 3/8-inch shank diameter fits standard collets and end mill holders

Compatibility

Designed as a standard single-end square end mill for use in milling machines, machining centers, and CNC routers accepting a 3/8-inch shank. Compatible with workpiece materials including steel, stainless steel, cast iron, and aluminum and non-ferrous metals.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before inserting the shank. Clamp the shank to the minimum recommended insertion depth specified by the toolholder manufacturer to prevent pullout under load. Verify spindle RPM and feed rate are appropriate for the workpiece material and cutting diameter before beginning the cut.
