Accupro 12185029 Square End Mill 7/32 in 2 Flute Carbide

Product Description

The ACCUPRO 12185029 is a double-end solid carbide square end mill designed for precision milling operations in metal, composites, and hard plastics. It measures 7/32 inches (0.2188 inches) in diameter with a 9/16-inch (0.5625 inches) length of cut and a 3/8-inch (0.3750 inches) shank diameter. The overall length is 3 inches. Featuring 2 spiral flutes with a 40-degree helix angle and a micrograin carbide grade, this end mill delivers clean, stable cuts at the feeds and speeds typical of high-performance carbide tooling. The bright, uncoated finish suits general-purpose applications where coating is not required or where regrinding is anticipated.

This end mill is suited for CNC machining centers, manual knee mills, and precision tool rooms handling ferrous and non-ferrous workpiece materials. The double-end configuration extends tool life and improves cost-per-edge value on production runs. Right-hand cutting and right-hand flute direction are standard. The center-cutting capability allows direct plunge entry into workpiece material without pre-drilling. It is sized for light to moderate material removal in finishing and semi-finishing passes where tight tolerances and surface quality are priorities.

Key Features

• Solid carbide micrograin construction for rigidity and wear resistance
• Double-end design provides two usable cutting ends per tool
• 40-degree helix angle supports smooth chip evacuation and reduced cutting forces
• Center-cutting capable — allows direct plunge milling without a pilot hole
• Bright/uncoated finish suitable for general-purpose use and regrinding
• Right-hand cut and right-hand spiral for standard CNC and manual mill setups

Compatibility

Designed as a standard shank solid carbide square end mill compatible with 3/8-inch collets and end mill holders on CNC machining centers and manual mills accepting straight-shank tooling.

Installation Notes

Installation and tool changes must be performed by a qualified machinist with the spindle fully stopped and machine power locked out per shop safety procedures. Ensure the collet or tool holder bore is clean and free of chips before seating the shank. Confirm runout with a dial indicator before production use, as excessive runout accelerates tool wear and degrades surface finish. Follow machine manufacturer torque specifications for collet nut tightening.
