Accupro 12183956 Ball End Mill 0.2188 in 2 Flute Carbide

Product Description

The ACCUPRO 12183956 is a solid carbide ball end mill designed for precision milling operations in metal cutting and machining applications. With a 0.2188-inch (7/32-inch) mill diameter and a 0.625-inch length of cut, this single-end tool delivers accurate profiling, contouring, and 3D surface work on a wide range of workpiece materials. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Micrograin carbide construction provides hardness and wear resistance suited to demanding shop environments. This end mill is intended for use by machinists and CNC operators working in production or job-shop settings.

This ball end mill is well suited for contour milling, slotting, and finish profiling on ferrous and non-ferrous metals, as well as plastics and composites. Its uncoated finish makes it a straightforward choice for general-purpose applications where coating compatibility with cutting fluids or specific materials is a consideration. The 1/4-inch shank fits standard collets and tool holders commonly found in vertical machining centers and CNC mills. The compact 0.2188-inch diameter is particularly useful for detail work, tight-radius features, and small-part machining.

Key Features

• Solid micrograin carbide construction for hardness and extended tool life
• 0.2188-inch (7/32-inch) ball nose diameter for precise radius profiling
• 40-degree helix angle for efficient chip evacuation and smooth cutting
• 2-flute, single-end design optimized for profiling and finish cuts
• Right-hand cut and right-hand spiral flute geometry
• Uncoated finish suitable for general-purpose machining applications

Compatibility

Designed as an OEM-style replacement or direct-use cutting tool for CNC vertical machining centers and manual mills accepting a 1/4-inch shank collet or tool holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and power is locked out before loading or changing tooling. Seat the 1/4-inch shank fully and evenly in the collet to the recommended gauge-line depth before torquing the collet nut. Verify runout with a dial indicator after tool mounting to confirm seating before beginning a cut.
