Accupro 12178600 Square End Mill 3/8 in 3 Flute Carbide

Product Description

The ACCUPRO 12178600 is a single-end, square-profile solid carbide end mill designed for precision milling operations in metal fabrication, tool-and-die, and general machining environments. It measures 0.375 inches in cutting diameter with a 0.625-inch length of cut and a 2-inch overall length. The micrograin carbide construction provides the hardness and edge retention needed for demanding cuts in ferrous and non-ferrous materials. A 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. This tool is intended for use by machinists and CNC operators working on mills, machining centers, and similar equipment.

This end mill is suited for stub-length milling applications where rigidity is a priority and deflection must be minimized. The three-flute, right-hand cut and right-hand spiral flute configuration is commonly used for general-purpose slotting, profiling, and peripheral milling. The centercutting geometry allows for plunge cuts into the workpiece. Uncoated carbide is appropriate for a range of base materials and is a practical choice when regrinding is expected.

Key Features

• Solid micrograin carbide construction for hardness and wear resistance
• 40-degree helix angle for efficient chip evacuation and reduced cutting forces
• Three flutes with right-hand cut and right-hand spiral for general-purpose milling
• Centercutting design allows direct plunge entry into the workpiece
• Stub length provides added rigidity and reduced deflection
• Uncoated finish suitable for standard machining and regrinding applications

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC machining centers and manual milling machines accepting a 3/8-inch straight shank end mill.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank firmly in a collet or end mill holder appropriate for a 0.375-inch diameter shank, ensuring proper tool runout before operation. Confirm spindle speed and feed rate settings match the material and cut type before engaging the workpiece. Power down and lock out the machine before changing tooling.
