Harvey Tool 73038 Square End Mill 0.038 in 4 Flute Carbide

Product Description

The HARVEY TOOL 73038 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 0.038-inch cutting diameter and a 0.114-inch length of cut, this tool is built for fine-detail work in tight geometries. The 4-flute configuration provides a good balance of chip evacuation and surface finish quality. A 30-degree helix angle promotes smooth cutting action and reduces chatter. The bright, uncoated finish makes it suitable for a range of ferrous and non-ferrous materials. This end mill is installed by machinists and CNC operators working in job shops, production machining, and precision component manufacturing.

This end mill is well suited for slotting, profiling, and light contouring operations in small-bore or fine-feature workpieces. The 0.125-inch shank diameter fits standard collets and toolholders commonly found on CNC machining centers and manual mills. Its 1.5-inch overall length keeps the tool rigid and minimizes deflection during cuts. The centercutting design allows for direct plunge entry. This tool is a practical choice for prototype shops, mold and die work, and any application requiring small-diameter, tight-tolerance milling.

Key Features

• 0.038-inch cutting diameter for fine-detail and small-feature milling
• Solid carbide construction for rigidity and wear resistance
• 4-flute geometry balances chip removal with finish quality
• 30-degree helix angle reduces cutting forces and chatter
• Centercutting capable, allowing direct plunge entry
• Bright uncoated finish suitable for broad material compatibility

Compatibility

Designed as a standard-shank replacement end mill with a 0.125-inch shank diameter, compatible with collets and toolholders accepting 1/8-inch shank tooling on CNC and manual milling machines.

Installation Notes

Installation should be performed by qualified machinists or CNC operators. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully in the collet and torque to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning production cuts to protect the tool and workpiece.
