Hertel E5060008 Ball End Mill 0.125 in 4 Flute Carbide

Product Description

The HERTEL E5060008 is a solid carbide ball end mill designed for precision milling operations in metal, composite, and hard-material applications. The 0.125 inch cutting diameter and 4-flute geometry deliver fine finish passes and contour work where rigidity and accuracy are critical. With a 0.75 inch length of cut and 2.25 inch overall length, this tool is sized for close-tolerance profiling, slotting, and 3D contouring on CNC machining centers and manual mills. Right-hand cutting and right-hand flute direction are standard for conventional spindle setups. Micrograin carbide substrate provides wear resistance and edge retention at elevated speeds and feeds.

This end mill is suited for job shops, tool rooms, and production environments running steel, stainless, aluminum, and similar materials where a small-diameter ball nose profile is required. Single-end construction means the tool is replaced when worn rather than flipped. The uncoated finish makes it a practical choice for applications where a specific coating is not required or where regrinding after use is anticipated. A 0.125 inch shank diameter matches standard ER collets and small-bore tool holders common on CNC mills and machining centers.

Key Features

• 0.125 inch cutting diameter with ball nose profile for contour and 3D milling
• 4-flute design for improved finish quality and material removal balance
• Solid micrograin carbide construction for edge retention and rigidity
• 0.75 inch length of cut suits shallow-to-medium depth profiling passes
• Right-hand cut and right-hand helix for standard CNC spindle compatibility
• Uncoated single-end tool suitable for regrinding programs

Compatibility

Designed as an OEM-style replacement or direct substitute for small-diameter ball end mills used in standard ER collet chuck systems and small-bore tool holders on CNC machining centers and manual milling machines accepting a 0.125 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before changing tooling. Seat the shank fully into the collet or tool holder to the recommended minimum engagement depth and torque the collet nut per the tool holder manufacturer specification. Verify runout with a dial indicator before beginning a cut, as excessive runout will accelerate edge wear on small-diameter carbide tools.
