Harvey Tool 846850-C3 Square End Mill 0.05 in 3 Flute

Product Description

The HARVEY TOOL 846850-C3 is a solid carbide square end mill designed for precise milling operations in demanding machining environments. With a 0.05-inch cutting diameter and three flutes, it delivers clean material removal at small-diameter scales where rigidity and surface finish are critical. The AlTiN coating provides high heat resistance and extended tool life when cutting hardened steels, stainless steels, and other abrasive materials. A 30-degree helix angle promotes efficient chip evacuation and reduces cutting forces. This end mill is a single-end tool and is center-cutting, allowing for plunge entry as well as peripheral and slot milling operations.

This end mill is suited for precision machining shops, tool-and-die operations, mold work, and aerospace or medical component manufacturing where tight tolerances and fine detail are required. The extended reach design, with a reach length of 0.45 inches and an overall length of 2.5 inches, accommodates deeper cavities and stepped-down features without sacrificing rigidity. It is intended for use by machinists and CNC operators working with high-speed or high-performance machining centers.

Key Features

• 0.05-inch cutting diameter for fine-detail and small-feature milling
• 3-flute geometry balances chip clearance with rigidity at small diameters
• AlTiN coating for high-temperature resistance and extended tool life in hard materials
• 30-degree right-hand helix with right-hand cutting direction for efficient chip evacuation
• Center-cutting capable — supports plunge, slot, and peripheral milling
• Extended reach design with 0.45-inch reach length for cavity and stepped-feature access

Compatibility

Designed for use in standard 1/8-inch collets or toolholders on CNC machining centers and manual mills capable of accommodating small-diameter solid carbide end mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the toolholder collet is clean and within proper runout tolerance before seating the 0.125-inch shank. Power down and lock out the spindle before changing tooling. Follow machine manufacturer guidelines for torque specifications on collet nuts, and verify runout after installation to protect the cutting edge at this small diameter.
