Value Collection 320-3760 Ball End Mill 3/4 in 4 Flute Hss

Product Description

The VALUE COLLECTION 320-3760 is a single-end ball end mill designed for milling contoured surfaces, slots, and complex 3D profiles in metal and similar materials. Built from high speed steel (HSS) with a bright, uncoated finish, it measures 0.75 inches in diameter with a 1-5/8 inch length of cut and a 3-7/8 inch overall length. The four-flute, spiral-flute geometry provides a balance of chip evacuation and surface finish quality. Right-hand cutting and right-hand flute direction are standard for use in conventional milling setups. Machinists and tool-and-die professionals use this style of end mill for both roughing and finishing passes on curved or radiused features.

This end mill is suited for use in manual knee mills, CNC machining centers, and similar vertical milling equipment. The 3/4 inch shank diameter fits standard ER collet chucks, end mill holders, and Weldon-style holders common in job shops and production environments. Standard length geometry makes it a practical choice for general-purpose operations where extended reach is not required. It is appropriate for cutting ferrous and non-ferrous metals in typical shop conditions.

Key Features

• Ball end geometry for milling radiused slots, contoured surfaces, and 3D profiles
• High speed steel construction provides toughness and resharpening capability
• Four-flute spiral design balances chip clearance and surface finish
• Right-hand cut and right-hand helix for use in standard milling spindles
• Bright, uncoated finish suitable for use with or without cutting fluid
• Single-end configuration; standard length for general-purpose reach requirements

Compatibility

Designed as a general-purpose replacement or stock end mill for vertical milling machines and CNC machining centers accepting a 3/4 inch shank via collet chuck or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's tooling specifications. Ensure the spindle is fully powered down and locked out before loading or removing the end mill. Confirm the shank is fully seated and securely clamped in the holder to the required engagement depth before operation. Inspect the cutting edges for damage or wear before each use and replace if chipping or dulling is evident.
