Value Collection 720-2170 Ball End Mill 7/16 in 2 Flute Hss

Product Description

The VALUE COLLECTION 720-2170 is a double-end ball end mill designed for milling contoured surfaces, slots, and three-dimensional profiles in metal and other machinable materials. Constructed from M2 high speed steel with a bright, uncoated finish, this end mill features a 7/16 inch cutting diameter, a 13/16 inch length of cut, and a 30-degree helix angle. The double-end design provides two usable cutting ends, extending tool life between changes. With two flutes and right-hand cutting and flute direction, it suits general-purpose profiling and finishing passes in shop and production environments. Machinists and tool and die professionals are the primary users of this tool.

This ball end mill is suited for use in vertical machining centers, knee mills, and CNC milling machines running conventional or climb milling operations. The 1/2 inch shank diameter fits standard ER and side-lock toolholders commonly found in production and job-shop settings. Standard length classification makes it appropriate for typical reach applications where extended reach is not required. The bright finish means no additional coating concerns during regrinding or resharpening of the secondary end.

Key Features

• Double-end design provides two cutting ends from a single tool
• M2 high speed steel construction for durability across a range of workpiece materials
• 7/16 inch ball nose diameter for profiling contoured and three-dimensional surfaces
• 30-degree helix angle supports smooth chip evacuation during milling operations
• Right-hand cut and right-hand flute spiral geometry for standard milling setups
• Bright/uncoated finish compatible with standard cutting fluids and coolants

Compatibility

Designed for use in milling machines and machining centers accepting a 1/2 inch shank diameter, including ER collet chucks and side-lock end mill holders commonly used with standard-length ball end mills in this size range.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout tolerances. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the holder. Verify shank engagement depth meets the toolholder minimum grip requirement to prevent pullout under cutting loads. Inspect both cutting ends for chipping or wear before use.
