Accupro 313621 Ball End Mill 3/8 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 313621 is a solid carbide ball end mill designed for precision milling of contoured surfaces, slots, and 3D profiles in a wide range of workpiece materials. It features a 3/8 inch diameter ball nose with a 1/2 inch length of cut and a 45-degree helix angle that promotes efficient chip evacuation and smooth surface finishes. The micrograin carbide construction delivers hardness and wear resistance suited to demanding cutting conditions. With a bright, uncoated finish, this end mill is well-suited for non-ferrous metals, plastics, and other materials where a coating is not required. It is a single-end tool with a right-hand cutting and flute direction.

This end mill is used in CNC machining centers and manual milling machines for profiling, contouring, and finishing operations. It is appropriate for job shops, tool rooms, and production environments where tight tolerances and consistent performance are required. The 3/8 inch shank diameter fits standard ER and side-lock collet systems commonly found in vertical machining centers. Its 2-1/2 inch overall length provides adequate reach for most standard depth-of-cut applications without excessive overhang.

Key Features

• Solid micrograin carbide construction for hardness and wear resistance
• 45-degree helix angle for efficient chip evacuation and reduced cutting forces
• Ball nose geometry for 3D contour milling and profile finishing
• Bright, uncoated finish suitable for non-ferrous metals and plastics
• Right-hand cut and right-hand spiral flute direction
• Single-end design with a 1/2 inch length of cut

Compatibility

Designed as a standard-shank solid carbide ball end mill compatible with 3/8 inch collet or end mill holders on CNC vertical machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool changer or spindle is locked before inserting or removing the end mill. Use a properly sized collet or end mill holder torqued to the machine manufacturer's specifications. Verify runout at setup to maintain tolerance and tool life.
