Milling Cutters

Iscar Metals Inc.'s Heli Tang T490 milling cutter for roughing accepts inserts with serrated, chip-splitting grooves. These grooves can improve performance when the machine power is limited or when evacuating chips from narrow slots or deep cavities, according to the company.

Emuge Corp. has introduced "circle-segment" cutters, a class of endmills designed to reportedly enable substantially more material removal with fewer passes in 5-Axis machining, over 80 percent cycle time reductions and up to 50 percent smoother surface finishes.

Walter has introduced the Walter Prototyp MC251 solid-carbide mill, positioned with the Advance product line designation. Advance referring to mid-level performance and price.

Seco has expanded the high-feed machining applicability of its Jabro-HFM JHF980 solid-carbide endmill with new 4- and 5-flute options. The additional flutes allow part manufacturers in industries such as aerospace and medical to achieve maximum productivity when performing face, slot and select plunge milling operations.

In response to both the growth in quantity and complexity of structural aerospace components, an updated range of CoroMill 390 Silent Tools has been developed by Sandvik Coromant. The upgraded Silent Tools dampening technology will allow machine shops to machine deep pockets on titanium aerospace frame parts with greater security and higher metal-removal rates.

As automakers strive for increasingly fuel efficient and environmentally friendly vehicles, they're turning away from traditional iron favorites such as gray and ductile iron (GCI and DCI) to compacted graphite iron, or CGI. Also known as vermiculate graphite iron, CGI's mechanical attributes meet or exceed its counterparts, sometimes drastically so. Unfortunately, CGI is also more difficult to machine, requiring cutting tools both tough and wear-resistant. And because of the continuing call for cost-effective machining solutions across all manufacturing industries, these tools must also offer a low cost per part and predictable tool life. For facemilling applications, Kennametal says that tool is Mill 16.

Introducing the Pramet Econ LN square shoulder milling cutter from Dormer Pramet. Its positive axial geometry reportedly allows for lower cutting forces and smoother machining.

The increased popularity of Swiss-style machine tools and the need for fast tool indexing with high repeatability and precision has inspired Iscar Metals to develop small-diameter cutting tools with precision indexing. The new PiccoAce system allows easy quick and easy clamping with modularity benefit of thousands of possible combinations between holders and bars.

The Jabro-Solid2 JS554 range of solid-carbide endmills from Seco Tools gains further utility and versatility with smaller neck diameter options. These latest tools provide greater clearance when machining complex components, such as those found in aerospace, medical and general machining applications.

OSG USA Inc. has introduced its highly anticipated 2017/18 Cutting Tool Solutions Catalog in print and digital versions. The latest catalog edition has more than 1,300 pages and features new products including EXOCARB ADF flat drills and PHOENIX PSTW indexable shoulder cutters, and many new expansions to the company's quality lines, such as the EXOCARB MAX-MINI drills, EXOCARB WDO drills, PHEONIX PXD indexable exchangeable head drills and PHOENIX PFB indexable ballnose endmills.

The new Carmex AMT (aluminum mill-thread) cutter delivers a fine surface finish, good chip evacuation and is constructed of solid carbide to absorb cutting forces in high-speed aluminum machining. Available in a cylindrical shank or Weldon shank, the AMT is designed to minimize the tendency of aluminum to stick to the cutting tool edges.

Mil-Tec Inc. says its HV5HD series endmills are ideal for machine shops and other manufacturing facilities that require flexibility and value. With a full range of cutter bodies and precision-ground carbide inserts, the tools can reportedly handle any application and material.
