End Mills

The RobbJack says its DM/MDM series with new carbide and coating combination, eliminates or reduces the need for polishing, reduces wear by 909 percent, holds tighter tolerances and lasts 450 percent longer than comparable carbides and coatings designed for hard metal applications.

With trochoidal milling, significant improvements in terms of tool costs, clamping, processing times and load on the machine components can be achieved in many applications compared to conventional milling. For this milling technique, MAPAL has expanded its OptiMill product range by adding mills for the machining of titanium and high-alloy steels, as well as for hard machining.

Rushmore USA's solid-carbide endmills from Travers Tool Co. Inc. reportedly ensure better chip evacuation and higher metal-removal rates. Cutting Tool geometry is designed to prevent failures as a result of aluminum sticking to the cutting edge.

Microcut, a manufacturer and distributor of miniature and microsized carbide cutting tools, has produced a 180-page catalog, It includes new lines of variable-helix 3-flute endmills in long-reach, long-shank, long-flute and corner-radius versions. In addition, 272-degree spherical endmills, miniature long-reach corner-rounding endmills, and 82-degree drill point mills are offered.

Fullerton Tool Co. offers a new multiple-flute endmill for high-speed machining, the Force. The Force is suitable for cutting steel, stainless steel, high-temperature alloys and titanium. The endmill also includes an advanced FC-20 coating, which allows the Force to machine wet or dry.

The 365 variable-helix endmill from Ultra-Tool International Inc. features the SmoothFlute geometry. From roughing to finishing, convention milling to HSM peel milling, the 365 offers increased productivity and tool life, according to the company.

A new 5-flute endmill for machining titanium is available from Advanced Tool Inc. It is for aggressive machining and extends tool life, according to the company.

West Ohio Tool Co. says its PCD tools have been proven to reduce costs, setup times and changeovers while maintaining the tight tolerances required in today's manufacturing operations. Several of the new cross-center tip drills continue to run in high-silicon aluminum with over 700,000 hits, showing no sign of wear, and the helical diamond-veined endmills have logged in excess of 10,000 linear inches trimming composite materials.

Manufactured at its facility in Cleveland, Melin Tool launches a wide range of styles and sizes of carbide microscale endmills that target applications found in mold shops, medical component and instrument manufacturers, and EDM departments.

YG-1 Tool Co. says it has changed the way you will look at general-purpose endmills. With YG-1's superior substrate and YG-1's proprietary coating on its GP endmills, the tools impart a fine surface finish on workpieces and extend tool life at a competitive price.

The RF 100 Diver family of high-performance, solid-carbide endmills from Guhring Inc. are capable of plunging and extreme ramping in alloy steel, cast iron and aluminum. The Diver is a variable-helix, 4-flute endmill with a special face geometry for drilling up to 2 diameters deep and ramping up to a 45° plunge angle.

Regal Cutting Tools has developed a variable-helix endmill that minimizes deflection and reduces vibration. This tool can be run at heavy feed rates to outperform carbide at half the cost when milling titanium, stainless steel and nickel-base superalloys, according to the company.
