Accupro 14788361 Square End Mill 3/8 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 14788361 is a solid carbide square end mill designed for precision milling operations in metal, composite, and engineering-grade plastic materials. Built with 2 helical flutes and a helix angle between 38 and 42 degrees, it delivers efficient chip evacuation and a clean, flat-bottomed cut. The centercutting geometry allows plunge entry directly into the workpiece without a pre-drilled hole. With a 3/8 inch mill diameter and 1-1/8 inch length of cut, it suits a range of slotting, pocketing, and profiling operations. Machinists and tool-and-die professionals working on CNC mills and manual knee mills commonly reach for this style of cutter.

This end mill is suited for use in vertical milling centers, CNC machining centers, and manual mills where a 3/8 inch cylindrical shank tool holder is in use. The 3 inch overall length provides adequate reach for standard-depth operations without excessive overhang. The solid carbide construction makes it appropriate for higher spindle speeds and harder workpiece materials compared to high-speed steel alternatives. It is a practical choice for job shops, tool rooms, and production environments requiring consistent geometry and surface finish on ferrous and non-ferrous materials.

Key Features

• Solid carbide construction supports higher cutting speeds and improved wear resistance versus HSS
• 2 helical flutes with a 38 to 42 degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge entry without pilot drilling
• 3/8 inch mill diameter with matching 3/8 inch cylindrical shank for standard collet and tool holder compatibility
• 1-1/8 inch length of cut accommodates moderate-depth slotting and pocket milling
• No chipbreaker geometry for smooth finish cuts on continuous passes

Compatibility

Designed as an OEM-style solid carbide square end mill replacement for milling applications requiring a 3/8 inch cylindrical shank and 2-flute geometry.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. The spindle must be fully stopped and the machine locked out before changing tooling. Insert the cylindrical shank fully into the collet or end mill holder and torque the retention mechanism per the tool holder manufacturer specification. Verify runout with a dial indicator after mounting to confirm proper seating before initiating a cut.
