Accupro 14883928 Ball End Mill 0.03 in 3 Flute Carbide

Product Description

The ACCUPRO 14883928 is a miniature solid carbide ball end mill designed for precision milling in tight geometries and small-feature applications. With a 0.03-inch cutting diameter and a 3-flute spiral configuration, this single-end tool delivers fine detail cuts with improved chip evacuation over 2-flute alternatives. The micrograin carbide substrate provides hardness and wear resistance suited to demanding materials. A 30-degree helix angle promotes smooth cutting action and reduced chatter. This tool is installed and operated by machinists and tool-and-die professionals working on CNC milling equipment in production or prototype environments.

This end mill is suited for small-feature contouring, slotting, and profiling in ferrous and non-ferrous materials. The miniature series designation reflects its application in precision machining contexts where standard-diameter tooling is too large. The 0.045-inch length of cut (LOC) and 1/4-inch neck length allow access to narrow pockets and recesses while maintaining rigidity. The 1/8-inch shank fits standard ER collet systems commonly found on CNC machining centers and high-speed spindles. Extended reach geometry supports operations where tool clearance is a constraint.

Key Features

• 0.03-inch ball end cutting diameter with 0.045-inch length of cut
• 3-flute spiral design for improved chip evacuation in fine-feature milling
• Micrograin solid carbide construction for hardness and dimensional stability
• 30-degree helix angle reduces cutting forces and chatter
• 1/4-inch neck length with extended reach geometry for deep pocket access
• Bright/uncoated finish suitable for non-ferrous and general-purpose milling

Compatibility

Designed for use in CNC milling machines and machining centers with 1/8-inch ER collet toolholding systems; fits standard miniature-series setups requiring a 0.03-inch ball end geometry.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully in a clean, undamaged collet and torque the collet nut to the collet manufacturer specification. Verify runout with a dial indicator before beginning cuts, as runout is critical at this diameter scale.
