Value Collection 320-3735 Ball End Mill 1/2 in 4 Flute Hss

Product Description

The VALUE COLLECTION 320-3735 is a single-end ball end mill designed for contouring, profiling, and 3D milling operations in metal and other machinable materials. It features a 0.5 inch mill diameter and a 1-1/4 inch length of cut, making it suitable for moderate-depth cavity work and radius milling. Constructed from high speed steel with a bright uncoated finish, this end mill delivers reliable performance in general-purpose machining applications. The 4-flute configuration provides a good balance between chip evacuation and surface finish quality. Right-hand cutting and right-hand spiral flute direction are standard on this tool, and it mounts via a 1/2 inch shank diameter.

This ball end mill is used in manual mills and CNC machining centers for tasks that require a full radius cutting edge, including slot milling with a rounded floor, contour profiling, and die work. It is appropriate for job shops, tool rooms, and maintenance machining environments where high speed steel tooling is preferred over carbide for interrupted cuts or setups where tool breakage is a greater risk. Machinists and CNC operators in industrial and trade settings are the primary installers and users of this tool.

Key Features

• 0.5 inch mill diameter with a full ball-end radius profile for contour and 3D milling
• 1-1/4 inch length of cut suited for moderate-depth profiling and cavity work
• 4-flute spiral design balances chip evacuation with improved surface finish
• High speed steel construction provides toughness in interrupted cuts and general-purpose applications
• Bright uncoated finish — ready to use out of the box or easy to regrind
• Right-hand cut, right-hand flute, single-end configuration for standard mill setups

Compatibility

Designed as a standard-shank single-end ball end mill compatible with 1/2 inch end mill holders, collet chucks, and milling machine spindles accepting a 1/2 inch shank diameter on both manual mills and CNC machining centers.

Installation Notes

This end mill is installed by a machinist or CNC operator into a compatible end mill holder or collet chuck rated for a 1/2 inch shank. Always confirm the machine spindle is fully stopped and locked out before changing tooling. Verify runout with a dial indicator after seating the tool, and confirm tool length offset in the machine controller before running a program. Avoid excessive overhang beyond the shank grip length to minimize deflection and chatter.
