Accupro 314762 Square End Mill 3/8 in 3 Flute Carbide

Product Description

The ACCUPRO 314762 is a solid carbide square end mill designed for precise material removal in milling applications. Built from micrograin carbide, this single-end tool features a 3/8-inch cutting diameter, a 2-inch length of cut, and a 37-degree helix angle that promotes efficient chip evacuation and smooth cutting action. Three right-hand spiral flutes deliver a balance of chip clearance and cutting edge strength. The bright/uncoated finish makes it well suited for non-ferrous metals, plastics, and general-purpose machining where coating is not required. Machinists and tool-and-die professionals select this geometry when consistent surface finish and dimensional accuracy are the priority.

This end mill is intended for use in vertical machining centers, CNC mills, and manual knee mills where a 3/8-inch shank is compatible with the collet or end mill holder. It is appropriate for slotting, profiling, and peripheral milling in shop environments handling aluminum, brass, plastics, and similar machinable materials. The 4-inch overall length provides sufficient reach for standard work-holding setups without introducing excessive overhang.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• 37-degree right-hand helix for efficient chip evacuation
• 3 right-hand spiral flutes balancing chip clearance and cutting edge strength
• Center-cutting capable — supports plunge and ramp entry
• Bright/uncoated finish suited for non-ferrous and general-purpose materials
• Tight shank diameter tolerance of +0.0001/-0.0004 inches for secure tool holding

Compatibility

Designed for use in 3/8-inch collets and end mill holders on CNC vertical machining centers and manual milling machines requiring a standard single-end square profile tool.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank to the recommended engagement depth in the collet or holder and torque the retention nut per the toolholder manufacturer specifications. Verify runout with a dial indicator before commencing a cut, and confirm spindle speed and feed rate are appropriate for the workpiece material.
