Value Collection 720-1545 Square End Mill 7/8 in 2 Flute Hss

Product Description

The VALUE COLLECTION 720-1545 is a single-end, square-profile end mill designed for milling operations on aluminum and non-ferrous materials. Built from M2 high speed steel with a bright uncoated finish, it features a 7/8 inch cutting diameter, a 3-1/2 inch length of cut, and a 5-3/4 inch overall length. The 2-flute, right-hand spiral geometry with a 37-degree helix angle promotes efficient chip evacuation in softer, gummier materials where flute clearance is critical. This is a long-series tool suited for setups requiring extended reach into pockets or stepped features.

This end mill is intended for use in milling machines, CNC machining centers, and manual knee mills where non-ferrous stock is being profiled, slotted, or pocketed. The 7/8 inch shank diameter fits standard ER or CAT toolholders sized for that bore. Center-cutting capability allows it to be plunged directly into the workpiece. Machinists, toolroom operators, and job-shop programmers working aluminum, brass, copper, or similar materials will find this a practical general-purpose choice in the long-series format.

Key Features

• M2 high speed steel construction for toughness and re-sharpenability
• 2-flute right-hand spiral geometry optimized for aluminum and non-ferrous materials
• 37-degree helix angle promotes chip flow and reduces built-up edge in soft metals
• Center-cutting design allows direct plunge entry without a pre-drilled hole
• Long-series length type with 3-1/2 inch length of cut for deep-pocket access
• Bright uncoated finish — suitable for re-sharpening without coating complications

Compatibility

Designed for use with milling machine spindles and toolholders accepting a 7/8 inch shank diameter. Primary workpiece material compatibility is aluminum and non-ferrous metals (material code N). Part of the VCCC-HSS-2-AL series.

Installation Notes

Installation requires a toolholder matched to the 7/8 inch shank diameter; verify runout with a dial indicator before cutting. Ensure the machine spindle is fully stopped and locked out before loading or removing the tool. Follow your facility or shop safety standards for eye protection and machine guarding during all milling operations. Consult published feeds-and-speeds tables for M2 HSS end mills in aluminum to avoid work-hardening or tool deflection on long-reach cuts.
