Walter-prototyp 5160615 Internal Thread Mill 3 Flute

Product Description

The WALTER-PROTOTYP 5160615 is a solid carbide internal helical flute thread mill designed for precision thread milling in ferrous and non-ferrous materials. With a 9.90 mm cutting diameter, 18 teeth per inch (TPI), and a TiCN coating for extended tool life and heat resistance, this mill produces accurate internal threads in a single helical pass. The 3-flute right-hand configuration provides a stable cutting action with efficient chip evacuation. Machinists and CNC operators working in job shops, production facilities, and aerospace or general manufacturing environments will find this tool suited for demanding threading applications.

This thread mill is intended for internal thread milling operations on CNC machining centers where helical interpolation is available. The 10.00 mm shank diameter fits standard ER or hydraulic toolholders commonly used in vertical and horizontal machining centers. With a 15.92 mm length of cut and 66.00 mm overall length, it is well suited for threading shallow to mid-depth bores. No coolant-through capability is present, so external coolant or air blast is recommended for chip management during operation.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding thread milling applications
• TiCN coating reduces friction and extends tool life compared to uncoated carbide
• 3 right-hand flutes with helical geometry for smooth cutting action and controlled chip flow
• 18 TPI for standard thread pitches commonly encountered in general machining
• 9.90 mm cutting diameter with a -0.30 mm tolerance for controlled thread form accuracy
• No coolant-through design - compatible with external flood or mist coolant setups

Compatibility

Designed for use in CNC machining centers capable of helical interpolation for internal thread milling operations with a 10.00 mm shank interface.

Installation Notes

Installation and operation should be performed by qualified CNC machinists or tooling technicians. Secure the shank in an appropriate precision toolholder and verify runout before use, as excessive runout will degrade thread quality and shorten tool life. Confirm that the machining center control supports helical interpolation before programming the thread milling cycle. Always follow machine manufacturer lockout and tool-change procedures when installing or removing the tool.
