Harvey Tool 16911-C3 Thread Mill M5x0.8 3 Flute Altin Carbide

Product Description

The HARVEY TOOL 16911-C3 is a solid carbide helical flute thread mill designed for cutting M5x0.8 threads in both internal and external configurations. With a 3-flute geometry and AlTiN coating, it is built for high-efficiency threading operations in hardened and abrasive workpiece materials. The cutting diameter is 0.1200 inches, the shank diameter is 0.1250 inches, and the overall length is 2.0000 inches. It is intended for use by machinists and CNC operators running thread milling cycles on machining centers.

This thread mill suits applications in precision machining environments where a single tool must handle both internal and external M5x0.8 thread forms. The 5/16-inch length of cut accommodates standard thread depths for M5 fastener profiles. Its compact shank diameter makes it compatible with collet systems commonly used in CNC machining centers handling small-diameter threading work in materials such as steel, stainless, titanium, and cast iron.

Key Features

• Cuts M5x0.8 internal and external threads with a single tool
• 3-flute helical geometry for improved chip evacuation and surface finish
• AlTiN coating extends tool life in hardened and abrasive materials
• Solid carbide construction for rigidity and dimensional stability
• 0.1250-inch shank diameter fits standard ER collet toolholders
• No coolant-through design — external coolant or mist lubrication applies

Compatibility

Designed for CNC machining centers using thread milling cycles; fits standard collet toolholders accepting a 0.1250-inch shank diameter. No specific machine or system compatibility was provided in the product data.

Installation Notes

Installation and operation should be performed by a qualified machinist or CNC operator. Secure the shank fully in a collet or toolholder to the manufacturer-recommended engagement depth before running. Confirm thread milling cycle parameters — including helical pitch, feed rate, and depth of cut — in the CNC control before spindle engagement. This tool does not support coolant-through delivery; apply external coolant or cutting fluid appropriate to the workpiece material.
