Accupro 12184876 Ball End Mill 0.375 in 4 Flute Carbide Altin

Product Description

The ACCUPRO 12184876 is a solid carbide ball end mill designed for precision milling of complex contours, curved surfaces, and 3D profiling operations. With a 0.375 inch cutting diameter and a 1.125 inch length of cut, this tool handles deeper passes without sacrificing rigidity. The 4-flute geometry and 40-degree helix angle promote smooth chip evacuation and improved surface finish across a wide range of workpiece materials. An AlTiN coating increases surface hardness and thermal resistance, extending tool life in demanding cutting conditions. This is a single-end, right-hand cut tool built from micrograin carbide stock for consistent edge integrity and dimensional stability throughout its service life.

This ball end mill is suited for machining centers and CNC milling operations in job shop, production, and tool-and-die environments. The long-series overall length of 3 inches provides extended reach for cavity work, deep pocket milling, and die finishing where standard-length tools cannot reach. The 3/8 inch shank diameter fits common ER and end mill holders. The AlTiN coating makes it well matched to hardened steels, stainless alloys, cast iron, and high-temperature alloys where heat generation at the cutting edge is a primary concern.

Key Features

• 0.375 inch ball nose diameter for accurate contour and 3D surface milling
• 1.125 inch length of cut supports deeper radial and axial engagement
• 4-flute, 40-degree right-hand helix for efficient chip evacuation and smooth finish
• AlTiN coating delivers high surface hardness and oxidation resistance at elevated cutting temperatures
• Micrograin solid carbide construction for precise edge retention and dimensional consistency
• Long-series 3 inch overall length extends reach for deep cavity and die work

Compatibility

Designed as a direct-fit replacement or standard addition for any CNC machining center or manual mill accepting a 3/8 inch shank end mill holder or ER collet system.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the holder to the recommended gage line and torque the retention hardware per the tool holder manufacturer specifications. Inspect the collet or holder for runout before engaging the cut, as excessive runout will reduce tool life and surface finish quality.
