Accupro 12185434 Solid Carbide Square End Mill 0.5 in 4-flute

Product Description

The ACCUPRO 12185434 is a solid carbide square end mill designed for both roughing and finishing operations in a single tool. With a 0.5-inch cutting diameter, 4-flute construction, and a 40-degree helix angle, it removes material aggressively while leaving a finish-ready surface. The chipbreaker geometry helps evacuate chips efficiently, reducing heat buildup and tool deflection. The stub-length profile adds rigidity, making this end mill well-suited for applications where chatter and tool flex are concerns. It is an uncoated, single-end tool with a right-hand cutting direction and right-hand flute spiral.

This end mill is used in general machining environments for milling steel, aluminum, and other machinable metals where a combination roughing and finishing pass is needed. The 0.625-inch length of cut and 0.5-inch shank diameter make it compatible with standard end mill holders and collet chucks on vertical and horizontal milling machines and CNC machining centers. The stub-length overall length of 2.5 inches suits setups with limited spindle clearance or shallow-depth cuts requiring maximum tool stability.

Key Features

• Solid carbide construction for rigidity and wear resistance
• 4-flute, 40-degree helix angle for combined roughing and finishing performance
• Chipbreaker geometry promotes efficient chip evacuation and reduced heat
• Stub-length profile increases tool stiffness and minimizes deflection
• Right-hand cut, right-hand flute spiral, single-end design
• Uncoated carbide substrate suitable for a wide range of ferrous and non-ferrous materials

Compatibility

Designed for use with standard 0.5-inch end mill holders, collet chucks, and shrink-fit toolholders on CNC machining centers and manual milling machines requiring a 0.5-inch shank.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Secure the shank to the full recommended engagement depth in the toolholder to prevent pullout under cutting loads. Verify runout with a dial indicator before initiating a cut, as excessive runout will reduce tool life and surface finish quality.
