Accupro 12177100 Ball End Mill 0.0313 in 4 Flute Carbide

Product Description

The ACCUPRO 12177100 is a solid carbide ball end mill designed for precision milling of contoured surfaces, slots, and complex 3D profiles in metalworking and machining applications. With a 0.0313 inch (1/32 inch) mill diameter and a 4-flute, right-hand spiral configuration at a 40-degree helix angle, this tool delivers efficient chip evacuation and smooth cutting performance in tight-tolerance work. The micrograin carbide substrate provides the edge retention and rigidity needed for small-diameter toolpaths where deflection control is critical. This is a single-end, uncoated tool suited for shops running conventional or climb milling operations on a CNC machining center or manual mill.

This end mill is intended for use in precision machining environments where small-diameter ball nose toolpaths are required, such as die and mold work, engraving, and fine detail contouring. The 0.0938 inch length of cut (3/32 inch) and 1.5 inch overall length make it appropriate for shallow-reach applications where rigidity is prioritized over extended projection. The 1/8 inch shank diameter fits standard collet systems common in CNC routers and machining centers. It is typically run by machinists and CNC operators in job shops, tool rooms, and production environments.

Key Features

• 0.0313 inch (1/32 inch) ball nose diameter for fine detail and contour milling
• 4-flute design with right-hand cutting and right-hand flute direction for efficient chip removal
• 40-degree helix angle promotes smooth cutting action and reduced chatter
• Micrograin solid carbide construction for superior hardness and edge retention
• Uncoated finish suitable for a range of ferrous and non-ferrous materials
• Single-end configuration with 1/8 inch shank for standard collet compatibility

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers, CNC routers, and manual mills equipped with 1/8 inch collet or chuck systems accepting single-end carbide end mills.

Installation Notes

This tool should be installed by a qualified machinist or CNC operator. Ensure the machine spindle is fully powered down and the collet is clean and free of debris before seating the shank. Confirm proper runout with a dial indicator after clamping, as small-diameter carbide tools are sensitive to collet concentricity. Follow the tool manufacturer and machine OEM guidelines for appropriate feed rates and spindle speeds for the specific workpiece material.
