Cutting Tools

CBN & PCD Inserts

Sumitomo electric is a renowned name in the field of metal cutting tools in the category of super hard materials they are world leaders. This particular category consist of materials like CBN and PCD which are much higher on hardness scale as compared to conventional materials like carbide or ceramic. Superior mechanical properties make them ideal for machining hardened steel, Hi Speed turning and milling of cast iron, machining exotic materials where heat generation is very high while cutting and similar tough applications where there is conventionally no option but to have grinding or poor tool life ultimately higher cost.

Diamond is composed of pure carbon atoms, arranged in a very special crystal orientation that gives it its unique physical properties. The physical properties of the diamond tools, specifically the extreme hardness and wear-resistance, make Motherson PCD tools so unique.

CBN & PCD Tools are most ideal for following application areas:

  • Hardened steel machining
  • Hi speed cast iron machining
  • Efficient machining of exotic materials like titanium and nickel base alloys
  • we also provide customized solution as per customer application for varied operations like hardened steel grooving on shafts, small Dia boring in hardened steel, high Speed Milling of Cast Iron components like Cylinder Block, Cylinder head, valve seat machining operations, precision machining of aerospace material like titanium and nickel-based alloy.

Carbide Drills

We offer a wide range of solid carbide drills, including micro drills, flat bottom drills, Beyond solid carbide drills, deep hole drills, and solid carbide drills for specific materials like aluminum, steel, stainless steels, irons, and other materials, to name a few.


Milling Cutter

Milling cutters are cutting tools typically used in milling machines to perform milling operations and occasionally in other machine tools. They remove material by their movement within the machine or directly from the cutter’s shape

End mills are those tools which have cutting teeth at one end, as well as on the sides. The words end mill are generally used to refer to flat bottomed cutters, but also include rounded cutters (referred to as ball nosed) and radiused cutters (referred to as bull nose, or torus). They are usually made from high speed steel or cemented carbide, and have one or more flutes. They are the most common tool used in a vertical mill.

Carbide Inserts

Carbide is more expensive per unit than other typical tool materials, and it is more brittle, making it susceptible to chipping and breaking. To offset these problems, the carbide cutting tip itself is often in the form of a small insert for a larger tipped tool whose shank is made of another material, usually carbon tool steel. This gives the benefit of using carbide at the cutting interface without the high cost and brittleness of making the entire tool out of carbide. Most modern face mills use carbide inserts, as well as many lathe tools and endmills. In recent decades, though, solid-carbide endmills have also become more commonly used, wherever the application’s characteristics make the pros (such as shorter cycle times) outweigh the cons.
