Endmills

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. With cutting diameters from 0.005” and lengths up to 30 diameters deep, Melin reports outstanding performance in titanium and aluminum alloys, graphite and steels and stainless alloys less than 40 HRC.

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.

HAIMER USA has introduced a new variable-helix carbide roughing endmill for cutting stainless steels and general steels. The Power Mill F1304NN series endmill combines variable-flute geometry with a roughing cord profile design for more stable milling in machines with limited horsepower.

Monolith extended-reach endmills from Ultra-Tool International Inc. have overall lengths up to 12" (304.8mm); runout at that length is 0.0003" (0.0076mm). SmoothFlute variable-helix, 5-flute, 45°-helix and roughing styles are available, as well as 2- and 3-flute tools for cutting aluminum.

Microcut Inc.’s line of miniature carbide endmills are from 0.002" to 0.125" (0.051mm to 3.175mm) in diameter and are available with long shanks and long reaches. The company offers AlTiN- and diamond-coated endmills and special rotary cutting tools, including thread mills, keyseat cutters, double-angle cutters, microdrills, spotting drills and dovetail cutters.

Cobra Carbide Inc.’s ADDER universal endmills have a 40° helix and a variable-flute geometry. According to the company, the endmills enable chatter-free milling in hard, ferrous materials and impart fine surface finishes. The coatings reportedly allow users to dramatically increase feeds and speeds, take deeper DOCs and extend tool life.

High performance cutting tool manufacturer M.A. Ford Mfg. Co. Inc., Davenport, Iowa, recently expanded its TuffCut® XT high performance Series 278 endmill product offering. More than 400 product line items have been added to include additional lengths of cut, corner radii and Weldon flat options. The corner radius offering is said to meet the needs of the aerospace manufacturing industry.
