Accupro 12185137 Square End Mill 3/8 in 4 Flute Carbide

Product Description

The ACCUPRO 12185137 is a double-end, solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. It features a 3/8-inch diameter, a 3/4-inch length of cut, and a 40-degree helix angle that promotes efficient chip evacuation and reduced cutting forces. Manufactured from micrograin solid carbide, the tool delivers dimensional stability and wear resistance at elevated cutting speeds. The bright, uncoated finish is suitable for a broad range of general-purpose milling applications. Both ends are usable, extending tool life and reducing per-cut tooling cost. This end mill is sized at 3-1/2 inches overall length with a matching 3/8-inch shank diameter.

This end mill is used in CNC machining centers, manual knee mills, and toolroom operations across job shops, maintenance departments, and production facilities. Its double-end configuration makes it a practical choice wherever general-purpose profiling, slotting, or peripheral milling is performed. The right-hand cut and right-hand spiral flute geometry suit standard machine spindle rotation. The regular-length body fits standard tool holders and collet chucks without extended-reach adapters.

Key Features

• Double-end design provides two usable cutting ends per tool
• Micrograin solid carbide construction for rigidity and wear resistance
• 40-degree helix angle promotes smooth chip flow and reduced chatter
• Center-cutting capable, allowing plunge entry into workpiece material
• Bright/uncoated finish compatible with a wide range of work materials
• Right-hand cut and right-hand flute direction for standard spindle operation

Compatibility

Designed as a general-purpose replacement or production end mill for standard 3/8-inch collet chucks, end mill holders, and milling arbors used in CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and powered off before loading or changing tooling. Seat the shank fully into the collet or tool holder to the recommended engagement depth, and verify runout before beginning a cut. Follow the machine tool manufacturer and tooling manufacturer guidelines for speeds and feeds appropriate to the workpiece material.
