Accupro 12182249 Square End Mill 3/8 in 3 Flute Carbide

Product Description

The ACCUPRO 12182249 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. Built from micrograin carbide and finished with an AlTiN (aluminum titanium nitride) coating, this tool delivers hardness and heat resistance suited to demanding cuts in ferrous and non-ferrous materials. It features a 3/8 inch cutting diameter, a 1-3/4 inch length of cut, and a 4 inch overall length that places it in the extra-long category. The 40-degree spiral helix promotes efficient chip evacuation and smooth cutting action. Licensed machinists, tool and die makers, and CNC machine operators are the primary installers and users of this tool.

This end mill is intended for use in vertical and horizontal milling machines and CNC machining centers. The extra-long overall length makes it suited to applications requiring extended reach into deep pockets, slots, or stepped features. The centercutting design allows plunge milling in addition to peripheral and slot cuts. Right-hand cut and right-hand flute orientation are standard for conventional and climb milling on most CNC and manual mill setups.

Key Features

• Solid micrograin carbide construction for edge retention and rigidity
• AlTiN coating provides elevated heat resistance for dry and semi-dry cutting
• 40-degree helix angle promotes efficient chip flow and reduced cutting force
• Centercutting geometry allows direct plunge entry without pre-drilling
• Extra-long 4 inch OAL with 1-3/4 inch length of cut for deep-reach applications
• 3 flutes balance chip clearance with rigidity at 3/8 inch diameter

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for standard 3/8 inch collet or end mill holder tooling systems on CNC machining centers and manual mills.

Installation Notes

Installation requires a clean, properly sized 3/8 inch collet or end mill holder torqued to the machine spindle per the machine manufacturer specifications. Inspect the tool shank and holder bore for debris or damage before seating. Follow all shop lockout and machine guarding procedures before changing tooling. Confirm runout with a dial indicator after mounting to ensure dimensional accuracy within the stated shank diameter tolerance of -0.0001 to -0.0004 inches.
