Hertel 06821847 Roughing End Mill 1-1/2 in 6 Flute Cobalt

Product Description

The HERTEL 06821847 is a single-end cobalt roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel, it resists heat buildup during heavy cuts, making it suitable for ferrous metals, stainless steel, and other tough alloys. The 1.5-inch diameter cutter carries 6 flutes in a right-hand cutting and right-hand flute configuration with a bright, uncoated finish. The shank measures 1.25 inches in diameter. Machinists and tool-and-die professionals use this cutter in vertical and horizontal milling machines for roughing passes before finish milling.

This end mill is suited for production and job-shop environments where high-volume roughing cuts are required. The 6-flute geometry distributes cutting load across more edges, reducing chatter and extending tool life under heavy chip loads. The regular-length design with a 4-inch length of cut and 6.5-inch overall length fits standard milling machine setups and longer-reach fixtures. It is a single-end, non-centercutting tool, meaning it is intended for peripheral cuts and side milling rather than plunge operations.

Key Features

• M42 cobalt high-speed steel construction for heat and wear resistance in tough materials
• 6-flute, right-hand cut geometry for efficient chip evacuation during roughing passes
• 1.25-inch shank diameter for rigid tool holding and reduced deflection
• 4-inch length of cut accommodates deep slotting and side milling applications
• Bright, uncoated finish suitable for use with cutting fluids or dry in appropriate materials
• Non-centercutting, single-end design — intended for peripheral and side milling only

Compatibility

Designed as an OEM-style replacement or direct-fit roughing end mill for standard milling machine setups accepting a 1.25-inch shank diameter in collet chucks, end mill holders, or set-screw holders.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholding specifications. Secure the 1.25-inch shank in a properly sized end mill holder or collet chuck and verify runout before operation. This is a non-centercutting tool — do not use for plunge cuts. Always power down and lock out the machine spindle before changing tooling.
