Mini-Type Thread Mills

The Mini Mill-Thread family is comprised of small solid-carbide thread mills. The tools in the family have been specially designed for the production of threads in very small bores. In order to achieve this, we’ve employed unique tool designs, accurate geometries, and quality coatings.

Features:

  • Low cutting forces thanks to the short profile
  • Can work under high cutting speeds, resulting in shorter machining times
  • Threading up to shoulder in blind holes

Our range of Mini-Type Thread Mill tools consists of the following lines:

 

MTS - THREAD MILLS WITHOUT INTERNAL COOLANT
The full-profile thread mills in this product line are compatible only with Internal threads (with the exception of tools for the G55° thread profile). They can be used to machine Titanium, surgical stainless steels, and hardened materials (up to 45 HRC) – as well as for general purpose threading.

Features:

  • Supports threads as small as ISO M1 x 0.25, and 0-80 UNF
  • The thread depth can be up to 5 x Thread Diameter (for some tools)
  • Multi (3-5) flutes
  • Suitable for high-speed air turbine machines (30,000-40,000 RPM), and for standard machining centres (6,000+ RPM)

Carbide Grade: MT7 - Sub-micron grade with multi-layer TiAIN coating. This is a general purpose grade, which can be used with all materials. (ISO K10-K20)

 

MTS – THREAD MILLS WITH INTERNAL COOLANT THROUGH THE FLUTES
The full-profile thread mills in this product line are capable of cutting Internal threads (only for UNJ and MJ profiles). Most of them come with internal coolant through the flutes.

Features:

MTSB - THREAD MILLS WITH INTERNAL COOLANT BORE
The full-profile thread mills in this product line improve on the basic MTS thread mills, by adding a coolant bore, and either 1 or 2 coolant holes. By providing a high-pressure stream of coolant fluid through the bore, we can wash the chips away from the thread during the cutting cycle – improving tool performance, and providing superior thread accuracy. An additional benefit is the efficient cooling of the tool’s cutting edge.

Features:

  • Supports threads as small as ISO M1.2 x 0.25, and 0-80 UNF
  • The thread depth can be up to 4 x Thread Diameter (for some tools)

Recommended Usage:

  • Thread milling operations in horizontal machining centres, especially cases where the chips are concentrated at the bottom of the thread, and external coolant can’t wash them away.
  • Complicated applications, when the external coolant is inefficient, or can’t reach the machined area
  • Cases where the tool collet is too close to the application pre-hole, which causes it to block the external coolant

Carbide Grade: MT7 - Sub-micron grade with multi-layer TiAIN coating. This is a general purpose grade, which can be used with all materials. (ISO K10-K20)
