If you are not already using carbide inserts for creating chips in your shop, switching to them can improve your output and accuracy, in no time. Choosing carbide inserts for manufacturing is like picking the superhero of metal cutting tools! These little powerhouses offer unbeatable speed, letting you zip through projects faster than ever. Their precision ensures each cut is spot-on, achieving tight tolerances as precise as a few thousandths of an inch or greater. With their excellent heat dissipation, thanks to the carbide content, the cutting edge stays sharp longer, meaning you spend less time changing setups and more time machining and making money – and if you choose coated inserts, the cutting edge stays cool and sharp by multiples. And let's not forget the cherry on top: carbide inserts give you that smooth, fine finish, making your products look as polished as they perform. Setup is quicker and easier too—simply change the insert instead of the entire cutting tool. So, why settle for anything less when you can have a tool that brings speed, precision, and a flawless finish to your manufacturing game?

Understanding Carbide Insert Nomenclature: Ever wondered what the nomenclature of carbide inserts really means? It can often seem like a crazy alphabet and numerical soup. Here are some common questions we receive:

What do the letters and numbers signify?

Shape: The first letter (e.g., the "T" in TNMG332GM) indicates the shape of the insert: T = Triangular, S = Square, C/D/V = Rhombic, W = Trigon, L = Rectangular, A = Parallelogram, R = Round.
Relief Angle: The second letter (e.g., the "N" in TNMG332GM) indicates the relief angle: C = 7°, D = 15°, E = 20°, N = Neutral (0°), P = 11°.
Accuracy/Tolerance: The third letter (e.g., the "M" in TNMG332GM) indicates the accuracy/tolerance of the cutting point, thickness, and inscribed circle.
Hole and Chipbreaker: The fourth letter (e.g., the "G" in TNMG332GM) indicates if the insert has a hole, a chipbreaker, and the shape of the hole.
Internal Circumference: The fifth position number (e.g., the "3" in TNMG332GM) indicates the internal circumference (I.C.) of the insert.
Thickness: The sixth position number (e.g., the "3" in TNMG332GM) indicates the thickness of the insert.
Corner Radius: The seventh position number (e.g., the "2" in TNMG332GM) indicates the corner radius of the insert.
Chipbreaker Style: The last two letters (e.g., "GM" in TNMG332GM) indicate the chipbreaker style of the insert.

How do I choose the right insert for my application?

Understand the material you are cutting and the speed and finish you wish to achieve.
Determine if you have a holder that fits the insert or if a new holder is needed.
Consider the method of coolant you will be using.
Assess the number of pieces you are cutting. For small runs, rely on your expertise. For long runs, we can provide expertise on the spindle to help you optimize setup, speed, and feed.

What are the differences between the various grades and coatings?

The grades and coatings are constantly changing to provide you the best cut for your application. Whether you go with a traditional C-2 for cast iron and non-ferrous metal with a recommended cutting speed of 150-400 SFM or you try a carbide insert with a more exotic CVD, chemical vapor deposition, or PVD, physical vapor disposition, coating, getting the right insert, the right grade, and the right coating makes all the difference in your final product. Let KBC and its world class manufacturers ensure that you make the right choice.
