Accupro 12179557 Square End Mill 1in 5 Flute Solid Carbide

Product Description

The ACCUPRO 12179557 is a single-end, square-profile solid carbide end mill designed for precision milling operations on a CNC machining center or manual mill. It carries a 1 inch cutting diameter, a 1-3/4 inch length of cut (LOC), and a 1 inch shank diameter, with an overall length (OAL) of 4 inches. The five-flute geometry increases chip load capacity and improves surface finish compared to standard four-flute tooling. An AlTiN (aluminum titanium nitride) coating provides elevated heat resistance and wear life, making this tool well suited for dry or semi-dry cutting conditions. Machinists and toolroom operators who run hardened steels, stainless, cast iron, or high-temp alloys at moderate-to-aggressive parameters will find this cutter a reliable workhorse.

This end mill is intended for general-purpose and production milling in job shop and manufacturing environments. Its regular-length profile and coarse pitch make it a practical choice for peripheral milling, slotting, and profiling passes in ferrous and non-ferrous materials. The centercutting design allows plunge entry, giving the operator flexibility when no pre-drilled entry point exists. Right-hand cut and right-hand flute orientation are standard for conventional CNC spindle rotation. The 30-degree helix angle balances chip evacuation with tool rigidity across a broad range of workpiece materials.

Key Features

• Solid carbide construction for rigidity and extended tool life compared to HSS or cobalt alternatives
• AlTiN coating delivers high-temperature hardness and oxidation resistance, supporting dry or minimal-coolant machining
• Five flutes provide a higher feed-per-tooth capability and improved finish on finishing passes
• Centercutting geometry allows direct plunge milling without a pilot hole
• 30-degree helix angle promotes efficient chip evacuation and reduces chatter tendency
• Right-hand cut, right-hand flute configuration matches standard CNC mill spindle rotation

Compatibility

Designed for use in CNC machining centers and manual vertical mills accepting a 1 inch straight shank. Suited for ferrous metals, stainless steels, cast iron, and high-temperature alloys where an AlTiN-coated carbide tool is appropriate.

Installation Notes

This end mill is installed by a machinist or toolroom operator using an ER collet chuck, end mill holder, or hydraulic toolholder rated for the 1 inch shank diameter. Verify runout at the holder before cutting to protect both the tool and the workpiece. Ensure the machine spindle is fully stopped and the control is in feed-hold or emergency stop before changing tooling. Follow the tool manufacturer and machine builder guidelines for speeds, feeds, and depth-of-cut parameters appropriate to the workpiece material.
