Harvey Tool 54280 Single Profile Thread Mill 10-32 Tpi

Product Description

The HARVEY TOOL 54280 is a solid carbide single profile thread mill designed to cut internal and external threads in the 3/4-10 to 3/4-32 range, covering 10 to 32 TPI in a single tool. With a cutting diameter of 0.495 inches, a 0.5 inch shank diameter, and a 4 inch overall length, this tool handles a wide TPI range without a tool change. The 6-flute geometry supports efficient chip evacuation and stable cutting in both through and blind hole applications. A bright, uncoated finish keeps the tool ready for use in a variety of materials without additional surface treatment considerations.

This thread mill is suited for CNC machining centers performing thread milling operations on ferrous and non-ferrous workpieces in job shop, production, and maintenance environments. The single profile design allows one tool to produce multiple thread pitches within the 3/4-10 to 3/4-32 range by adjusting the helical interpolation path programmed at the machine. It is typically installed by machinists and CNC programmers working in metalworking, aerospace, die and mold, and general manufacturing applications.

Key Features

• Covers 10 to 32 TPI in one tool, reducing tool inventory for 3/4 inch thread families
• Cuts both internal and external threads using helical interpolation
• Solid carbide construction for rigidity and wear resistance
• 6 flutes for improved chip load distribution and surface finish
• 0.325 inch neck diameter and 1.75 inch neck length provide clearance in deeper thread features
• Bright, uncoated finish compatible with a range of base materials and cutting fluids

Compatibility

Designed for use in CNC machining centers with helical interpolation capability. Accepts a 0.5 inch tool holder or collet. Suitable for producing 3/4 inch unified threads from 10 to 32 TPI in internal and external configurations.

Installation Notes

Thread milling with this tool requires a CNC machining center capable of 3-axis helical interpolation. Tool runout should be minimized using a precision collet or shrink-fit holder to maintain thread accuracy. Verify spindle speed, feed rate, and helical pitch settings in the CAM program or G-code before cutting. Always confirm workpiece fixturing and clamping before beginning the thread milling cycle.
