Accupro 12465453 Ball End Mill 0.027 in 2 Flute Carbide

Product Description

The ACCUPRO 12465453 is a solid carbide ball end mill designed for precision milling of small-radius features, contours, and complex geometries in metalworking and machining applications. At 0.027 inches in diameter with a 0.04-inch length of cut, this miniature-series tool operates in the micro-machining range where rigidity and material grade are critical. The micrograin carbide construction provides the hardness and edge retention needed to hold tight tolerances in demanding cutting conditions. A 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. The bright, uncoated finish makes it well suited for non-ferrous metals, plastics, and other materials where coating adhesion or heat buildup is a concern.

This end mill is intended for use in CNC machining centers, CNC mills, and high-speed spindle setups where small-feature work is required. The 1/8-inch shank diameter fits standard collets commonly found in benchtop CNC routers and full-size machining centers alike. Its stub-length classification and single-end configuration make it appropriate for short-reach slotting, profiling, and finishing passes in mold-making, die work, prototype machining, and precision component manufacturing.

Key Features

• 0.027-inch ball nose diameter for micro-scale radius milling and contour work
• Solid micrograin carbide construction for edge retention and dimensional stability
• 30-degree helix angle promotes chip flow and reduces cutting resistance
• Bright/uncoated finish suitable for non-ferrous metals, plastics, and composite materials
• Right-hand cut and right-hand spiral flute configuration
• Stub length, single-end design for maximum rigidity in short-reach applications

Compatibility

Designed as a miniature-series replacement or standard-stock ball end mill compatible with any CNC machining setup accepting a 1/8-inch shank collet or tool holder.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's collet torque and runout specifications. Verify spindle and collet concentricity before seating the shank, as runout at this diameter range will directly affect tool life and surface finish. Power down and lock out the machine before changing tooling. At 0.027 inches in diameter, the tool is highly susceptible to breakage from side loads, improper feed rates, or excessive depth of cut - always confirm feeds and speeds against the material being cut before beginning a pass.
