Cutter helically mills, cuts and
finishes threads
Thread milling cutters catalogue includes the UNI thread miller, which helically mills the core hole, cuts the thread and chamfers or counterbores the first thread.
The range of thread milling cutters in WNT's 22-page catalogue includes cutters manufactured from solid carbide and the latest indexable insert designs The catalogue includes WNT's UNI thread miller

Cutters make light work of hard materials
Tool life when cutting hard materials up to 70 HRc is greatly improved, thanks to the development of a PVD-multilayer coating used on solid carbide milling cutters.
This product produces its own hole by helically milling the core hole, cutting the thread and chamfering or counterboring the first thread to finish off the operation.
The UNI thread miller is available in six diameters from 4.51mm through to 14.38mm.
Then there are tools for cutting a number of different thread sizes and forms (M, MF, G, UNC and UNF), LH or RH, at up to a 3x diameter/depth ratio.

Tooling catalogue grows to over 5000 products
The latest release of the WNT catalogue has been expanded to over 1200 pages, has 18 sections and over 5000 tooling products including fine-boring, reaming, threading, milling and toolholding.
The UNI cutters provide are cost-effective for low to medium volume production.
To help subcontractors who are having to cope with smaller work batches and don't want to hold large stocks of tools, WNT is making its solid carbide type UNI thread milling cutter available ex-stock.
"For the small to medium-sized sub-contractor that make up the majority of our customers in the UK the availability of the type UNI makes perfect economic sense," said Adrian Fitts, WNT (UK) Business Development manager.
"The simple fact that one tool replaces three is the first obvious cost saving.
However, further benefits are that it frees up valuable space in the machine's tool carousel and reduces the number of tool changes and associated positional moves required to complete the threading operation.
Even on relatively low batch sizes these time savings can be significant," commented Fitts.
The UNI thread milling cutters have standard through coolant to aid swarf evacuation, so are extremely well suited to cutting difficult to machine and hardened materials up to 60 HRC.
Die and mould makers will benefit from hard machining to avoid machining dies in the soft state before to heat treatment.
Otherwise, threads machined before heat treatment can be deformed by the hardening process, resulting in additional rectification work.
With type UNI, the threads are produced after heat treatment so positional accuracy and thread forms are guaranteed to be correct, first time.
Also of particular interest for mould and die makers, type UNI thread milling cutters are also available, ex-stock, with a diamond coating for the machining of graphite.
The only constraints to using WNT's type UNI solid carbide thread mills are posed by machine capabilities.
The machine used must have the capability to interpolate and feed at the thread pitch and be able to achieve that at a suitable rev/min for the particular cutter being used.
Through tool coolant is also a positive contribution to producing threads of a consistent high quality.
"While our extensive range of thread milling cutters will provide a solution to the majority of applications, the pressure faced by all manufacturing companies to reduce costs and lead times is hard to ignore.
As such, the ability to complete three operations with a single cutter is proving to be a major advantage, particularly within the sub-contract sector," confirmed Fitts. Request a free brochure from WNT (UK) ...
