Solid Carbide
End Mills

MORSE offers complete selections of solid carbide end mills for many milling applications. Tools are available for roughing, semi-finishing and finishing operations and for almost any material. The company provides the best solutions for stainless steel, titanium, Inconel, aluminum and HRSA alloys.

MORSE solid carbide end mill products are produced from a high quality carbide grade with optimized grinding process and top PVD coating. The high quality places the company incisively in the global market, die & mold, aerospace, medical, power generation and general machining industries.

MORSE’s family of FMR, Fast Metal Removal, is comprised of high tech solid carbide cutting tools based on the newest submicron carbide technology and tool coatings. These tools are well-suited for high speed machining, the machining of hardened material up to 60 Rockwell range and even dry machining. In addition to superior substrates and coatings, MORSE offers these tools in a unique ‘shredder’ style rougher geometry. These tools reduce chip thickness and size and promote higher feed rates than conventional solid carbide tools.

The solid carbide end mills family comes in the full range of endmill configurations for ball nose, flat bottom, center cutting and ramping applications. A variety of stub lengths, long lengths, helix angles and flute combinations are available. The tools feature the MC08 submicron carbide substrate for greater strength and performance. Coatings used on the solid carbide end mills are designed specifically for demanding applications.

The heart of the solid carbide end mills is the unique submicron carbide used to make them. Conventional carbide end mills most often use what is known as ‘micro grain carbide’. In this condition, the particles of carbide in the material approach approximately a micron in size. This structure produces a very tough material that is not prone to breakage under normal cutting conditions. However, in order to remain strong, it loses hardness. This limits the hardness of the material that it is able to cut and the heat that it is able to withstand. The new submicron carbide used in solid carbide end mills has transverse rupture strength of over 580,000 PSI. [4 MPa] This makes them even stronger than high speed steel and they are the hardest of all carbides produced. There is a high hardness for machining at elevated temperatures and machining hardened materials. At the same time there is excellent strength in the material for superior chip loads and depths of cut. The submicron microstructure also allows for sharper and more uniform cutting edges.

The solid carbide end mills line is available with the latest PVD titanium aluminum nitride coating in grade MC93. This coating is specifically made for hardened material or dry machining, with excellent thermal properties. It resists heat transfer into the tool and provides superior tool life. Other tools designed for machining nonferrous materials such as aluminum are available with large chip gullets and polished to reduce chip welding.

In high metal removal applications a major concern when working with carbide end mills is double-cutting chips. This is usually fatal to the tool. MORSE’s solid carbide roughers provide a solution to this problem. The serrated cutting edge produces a fine hair-like chip that can be easily blown or flushed from the cutting zones. The reduced pressure in the cut permits a significantly higher feed rate. As feed rates increase, cycle times decrease. When cycle times are lower, profits are higher.

The new solid carbide end mills products from the Fast Metal Removal product family are designed for today’s manufacturing. Improved carbide substrates, coatings and geometries will help to meet the demands of better performance and to increase profits.
