Accupro 12178695 Square End Mill 0.5 in 7 Flute Solid Carbide

Product Description

The ACCUPRO 12178695 is a 7-flute solid carbide square end mill designed for high-efficiency milling in demanding machining environments. Built from micrograin solid carbide with an AlTiN finish, it delivers extended tool life and heat resistance in hard and abrasive materials. The 0.5-inch cutting diameter pairs with a 1.625-inch length of cut and a 4-inch overall length, making it well suited for medium-depth slotting and peripheral milling operations. The 37.5-degree spiral helix angle promotes smooth chip evacuation and reduces chatter. Right-hand cut and right-hand flute geometry are standard. This end mill is installed by machinists and CNC operators in production and job-shop environments.

This end mill is appropriate for use in CNC machining centers and manual mills where high flute count is needed for superior surface finish and feed rate capability. The centercutting design allows plunge entry, adding flexibility for ramping and helical interpolation strategies. The AlTiN coating makes it particularly effective in dry or semi-dry cutting of ferrous alloys, hardened steels, and stainless. The 0.5-inch shank diameter provides direct collet or end mill holder mounting without adapters.

Key Features

• 7-flute geometry for improved surface finish and higher feed rates vs lower-flute-count tools
• Micrograin solid carbide substrate for rigidity and wear resistance
• AlTiN finish for heat resistance in dry and hard-material cutting
• 37.5-degree helix angle promotes efficient chip evacuation and reduces vibration
• Centercutting capable — supports plunge, ramp, and helical entry
• Right-hand cut, right-hand flute spiral flute configuration

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 0.5-inch collets, end mill holders, and shrink-fit holders on CNC and manual milling machines.

Installation Notes

Installation is performed by machinists using a collet chuck, end mill holder, or shrink-fit toolholder sized for a 0.5-inch shank. Ensure the machine spindle and toolholder are clean and free of debris before clamping. Do not exceed the toolholder's rated runout tolerance, as excessive runout accelerates edge wear on high-flute-count carbide end mills. Always confirm spindle direction matches the right-hand cut orientation before engaging the workpiece.
