New End-Mill Series for Dental Machining

Emuge combines carbide construction with advanced geometries, coatings

The new end mill series are constructed in carbide with various coatings, including TiAlN, CrN, and a diamond coating that prolongs long tool life when machining ZrO2.

Earlier this year Emuge Corp. introduced a line of end mills for dental prosthetics manufacturing. Carbide construction, cutting geometries, and coatings have been engineered specifically for use with today’s dental materials.

Influenced equally by advances in design, materials science, and cosmetics, dental prosthetics is a rapidly developing specialty that demands precision, speed, and multiple skill sets. According to Stephen Jean, milling products manager at Emuge Corp., the new end mill line is an “application specific” result of a close examination of the market for dental prosthetics manufacturing.

Emuge’s new tool line consists of solid carbide ball nose and torus end mills that are designed for optimal machining of zirconium oxide, Polymethyl methacrylate (PMMA), wax, cobalt chrome, and titanium – the most commonly used materials in making dental prosthetics. Both types of cutters have a radius tolerance of up to +/-0.005 mm and a diameter tolerance of 0.01 mm. Ball nose cutters are available in cutting diameters ranging from 0.4 to 6 mm. Torus end mills are available in cutting diameters of 3 and 4mm.

Solid carbide ball nose end mills are ideal for roughing and finishing, and their optimized geometry provides greater stability in long reach applications. The tapered neck ball nose end mills provide greater rigidity against deflection and are optimal for finishing and rest material machining. Torus end mills are available with two or four flutes, offering exceptional performance for roughing in cobalt chrome.

Emuge developed its new end mill line to be “application specific” following a close examination of the market for dental prosthetics manufacturing.


Emuge offers its dental end mills with a variety of coatings, including titanium aluminum nitride (TiAlN), which protects the tool from premature wear when machining non-precious metal alloys; chromium nitride (CrN), which prevents the material from sticking to the cutting edge of the tool when milling PMMA and wax; and a diamond coating that ensures extremely long tool life when machining zirconium oxide (ZrO2).

“As an industry leader, Emuge is committed to being at the forefront of new technology for emerging manufacturing opportunities,” Jean asserts.

The new dental line is suitable for use with various machine tools used in dental prosthetics manufacturing, from bench top systems to 5-axis machining centers. The tools are compatible with all the relevant software systems, too, including hyperDENT® CAM software from Emuge’s technical partner, OPEN MIND Technologies USA Inc.
