Accupro 12177098 Square End Mill 1 Inch 4 Flute Solid Carbide

Product Description

The ACCUPRO 12177098 is a single-end square end mill designed for precision milling operations in metal and composite materials. Built from micrograin solid carbide, it offers the rigidity and edge retention needed for demanding cutting applications. The 1 inch diameter with a 40-degree helix angle and spiral flute geometry promotes efficient chip evacuation and reduces heat buildup during cuts. With four flutes and a centercutting design, it handles both plunge and peripheral milling. Machinists and toolroom operators working with CNC machining centers or manual mills will find this tool well-suited for finishing and semi-finishing passes.

This end mill fits standard 1 inch diameter tool holders and collet chucks. It is appropriate for use in general-purpose milling of ferrous and non-ferrous metals, plastics, and composites. The right-hand cut and right-hand flute configuration is the standard orientation for conventional CNC mill setups. The 1.75 inch length of cut and 4 inch overall length make it a good fit for medium-depth pocketing, slotting, and profiling operations where rigidity is a priority over extended reach.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• 40-degree helix angle promotes smooth cutting action and efficient chip evacuation
• Centercutting design allows direct plunge entry into the workpiece
• Four-flute spiral geometry balances material removal rate with surface finish quality
• Right-hand cut and right-hand flute - standard orientation for most CNC and manual mills
• Uncoated finish suitable for aluminum, non-ferrous metals, and applications where coating is not required

Compatibility

Designed for use in standard 1 inch diameter end mill holders, collet chucks, and shrink-fit tooling systems on CNC machining centers and manual vertical mills.

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 into the holder to the minimum engagement depth recommended for the holder type and verify runout with a dial indicator before cutting. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material.
