Hertel E5018040 Ball End Mill 0.625 in 2 Flute Solid Carbide

Product Description

The HERTEL E5018040 is a single-end ball end mill designed for contour milling, profiling, and 3D machining operations in metal and composite materials. Built from solid carbide, it delivers the rigidity and wear resistance required for demanding cutting conditions. The 0.625-inch diameter cutting end pairs with a 3-inch length of cut (LOC), giving machinists substantial reach for deep-cavity work. With a 30-degree helix angle and right-hand flute direction, chip evacuation stays consistent across a wide range of feed rates. This tool is installed and used by CNC machinists and toolroom operators in production and job-shop environments.

The E5018040 suits milling centers and CNC machining cells running ferrous and non-ferrous workpieces where a ball-nose profile is required. Its 6-inch overall length (OAL) accommodates extended-reach setups without requiring a specialty holder. The 5/8-inch shank diameter fits standard ER and side-lock collet systems. Because the tool is uncoated, it is well-suited for operations where coatings may be cost-prohibitive or where re-grinding is part of the shop workflow.

Key Features

• Solid carbide construction for superior rigidity and wear resistance versus high-speed steel alternatives
• 0.625-inch ball-nose diameter for accurate contour and 3D profiling cuts
• 3-inch length of cut supports deep-cavity and stepped-surface milling
• 30-degree helix angle promotes smooth chip flow and reduces cutting forces
• Right-hand cut and right-hand flute direction for standard spindle operation
• Uncoated finish allows for straightforward re-grinding and cost-effective tool management

Compatibility

Designed as an OEM-style solid carbide ball end mill compatible with standard 5/8-inch ER collet chucks, side-lock holders, and shrink-fit tooling systems used on CNC vertical and horizontal machining centers.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's tooling and runout specifications. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing or seating the tool. Verify collet condition and holder cleanliness before clamping to avoid runout that can damage the cutting edge. Consult the machine's programming documentation for appropriate speeds and feeds based on workpiece material and depth of cut.
