What are top-notch inserts? A top-notch insert is a cutting tool insert often used for grooving and threading on finishing operations or for profile finishing applications. The unique design of the insert includes two cutting edges, or “top-notch,” which allows for precise and repeatable cuts with minimal heat and stress on the workpiece. Top-notch inserts come in a variety of
sizes that can accommodate almost any part feature, no matter how small or large.

Materials: Top-notch inserts are available in a range of materials, including carbide, ceramic, and coated carbide. CBN and PCD-tipped top-notch inserts are used for hardened steel, cast iron, or non-ferrous applications.

Applications: 

• Aerospace: One of the primary applications of top-notch inserts is manufacturing aerospace components. The aerospace industry requires high-quality, precise cuts that meet tight tolerances, and top-notch inserts are well-suited to this purpose. Top-notch inserts can be used to finish turbine blades and compressor discs, among other aerospace components. 
• Automotive: The automotive industry is another sector that uses top-notch inserts in manufacturing. Engine blocks, cylinder heads, and transmission housings, along with gears and shafts require smooth, precise finishing, and top-notch inserts are an excellent tool for achieving this result.
• Medical/Electronics: Other industries that utilize top-notch inserts include the medical and electronics industries. In medical manufacturing, top-notch inserts are used to create various bone screws and tap thread forms. Top-notch inserts are used to make various sizes and grooves on the screws or other components. In electronics manufacturing, top-notch inserts can be used in producing semiconductors, due to their compatibility and flexibility to create such a variety of features in a very economical way.

Benefits of top-notch inserts: One of the primary benefits of top-notch inserts is the ability to create a double-edged grooving and threading tool that is highly repeatable and precise, with a very economical platform. Top-Notch inserts are extremely durable due to the many materials that they can be used to manufacture. With proper use and maintenance, top-notch inserts can provide long tool life, reducing the need to for frequent replacement and downtime.

Top-notch inserts are versatile cutting tools that can be used in various industries, including aerospace, automotive, medical, and electronics. Their unique design allows for precise cuts with minimal heat and stress on the workpiece, making them an ideal choice for finishing operations that require high levels of precision and quality. From straight grooving inserts to hook tools that can groove or thread at 90° or more from the axis of the tool holder. With the addition of CBN and PCD tipping, along with the carbide and ceramic variations, no application is too hard to conquer.
