Hertel E699924736 Ball End Mill 5/16 in 3 Flute Carbide Tin

Product Description

The HERTEL E699924736 is a single-end ball end mill designed for precision milling operations in metal and alloy workpieces. Built from micrograin solid carbide, it delivers the rigidity and wear resistance required for high-speed profiling, contouring, and finishing cuts. The cutting end is TiN coated to extend tool life and reduce friction at the cutting edge. With a 0.3125 inch diameter and a 3-flute geometry set at a 30-degree helix angle, this end mill produces smooth surface finishes while maintaining chip evacuation efficiency. It is installed and run by machinists and CNC operators working in job shops, production environments, and tool rooms.

This end mill is suited for milling ferrous and non-ferrous metals in both manual and CNC machining centers. The ball-end geometry makes it appropriate for 3D contour work, radius profiling, and die and mold applications where a flat-bottom finish is not required. The 0.8125 inch length of cut provides adequate reach for moderate-depth profiling passes without excessive tool overhang. The right-hand cut and right-hand flute direction are standard for conventional CNC spindle configurations.

Key Features

• Micrograin solid carbide construction for rigidity and extended tool life
• TiN coating reduces cutting friction and improves wear resistance
• 3-flute design balances chip evacuation with surface finish quality
• 30-degree helix angle supports smooth cutting action in profiling passes
• Ball-end geometry suited for 3D contouring, radius milling, and die work
• Right-hand cut and right-hand flute direction for standard CNC spindle use

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 0.3125 inch shank diameter collet or tool holder.

Installation Notes

Installation is performed by a machinist or CNC operator using a compatible collet chuck or end mill holder sized for a 0.3125 inch shank. Confirm runout at the tool holder before beginning a cut. Verify spindle speed and feed rate against the material being machined and the manufacturer's recommended cutting data for carbide TiN-coated tooling. Never exceed the tool's rated depth of cut for the selected number of flutes and helix configuration.
