The cross-section highlights the differences in the design of the insert, such as the fixing holes, countersinks, and special features. This dictates what clamping method would be used to fix the insert on to the tool holder.

The thickness of a turning insert is measured from the bottom of the insert to the top of the cutting edge. This will be shown as a 2-digit number except where the insert features a T and then a single digit number eg T3. This is due to the fact that there are more than one increment within each mm. eg 03 is 3.18mm whereas T3 is thickest at 3.97mm.
In this blog, we will discuss how to identify all these key dimensions, so you will never need to check for part numbers again.
45° cutting edge | D.O.C. max. 0.138" (3.5mm) • Positive axial rake, positive radial rake • 45-degree cutting edge • Inserts have 8 cutting edges • Screw clamping
Round edge | D.O.C. max. 0.236" (6.0mm) • Superior perpendicularity and minimized cutting loads • Optimized for high-quality surface finishes • High rake angle lowers cutting loads and minimizes burrs • High-speed and high-feed capability improve productivity
90° cutting edge | D.O.C. max. 0.394" (10.0mm) • Positive axial rake, positive radial rake • 35-degree rhombic inserts with two different nose radius options • High polish for excellent surface finish and reduced built-up edges • Large chipbreaker grooves for controlled chip evacuation • Low cutting forces due to the positive cutting edge
The nose radius of an insert can affect the performance. A larger nose radius can result in the use of higher feed rates, and larger depths of cut, and they can handle more pressure, making them much better for heavier metal removal. Whereas a turning insert with a smaller nose radius can only take smaller depths of cut, they also have weaker cutting edges, and they can only handle a small amount of vibration but are much better for finishing as they are sharper and have less surface contact.

45° cutting edge | D.O.C. max. 0.236" (6.0mm) • Negative axial rake, positive radial rake • Double-sided, extra-thick insert with 8 cutting edges • Low cutting loads and excellent smooth cutting
Tolerance dimensions are indicated by a letter ranging from A - U. Dimension A relates to the inscribed circle (IC), dimension B relates to the insert height (for pentagon, triangle, and trigon shapes – for other polygons, the dimension B relates to the distance that is measured along the bisector of the corner angle) and dimension T relates to the thickness of the insert.
17.23° cutting edge | D.O.C. max. 0.07" (1.8mm) • Negative axial rake, negative radial rake • Positive rake angle for lower cutting forces • Strong vibration and impact resistance • Large chip pocket for smoother chip evacuation
It is a 2-digit number that generally indicates the width or length, however this is only applicable to insert shapes with no IC (inscribed circle), such as rectangular and parallelograms.

There are several variables that go into choosing the correct insert for your milling operations: the specific cutter body being used (milling cutter series), the type of machining operation (toolpath type), the cutting-edge angle (lead angle), the depth of cut, the materials being cut, and more. Use the filters on the left-hand side below to narrow down your choices, and find the inserts you need.
45° cutting edge | D.O.C. max. 0.236" (6.0mm) • Positive axial rake, positive radial rake • Large rake angle for faster, easier cutting • Inserts with 4 cutting edges
The relief angle for a milling insert is of paramount importance in achieving efficient and successful machining operations.
90° cutting edge | D.O.C. max. 0.67" (17.0mm) • Designed for high-speed machining of aluminum • Buffed surface for smooth chip evacuation and reduced BUE • High rake angle for good surface finish and lower cutting loads • For square shoulder milling and curved surface machining
Milling Cutter Series: Filter by the Haas Milling Cutter Series to find all the inserts available for that specific cutter. If you don’t know the cutter series (or have a non-Haas cutter body), you can also filter by insert style (shape), or ANSI designation.
For insert shapes such as round, square, triangle & trigon, this would then indicate the diameter of the inscribed circle (IC).
Choosing the right insert shape for your turning tool is essential. The shape of the insert can affect the vibration during operation, the ability to turn complex contours, the strength of the insert and its ability to take bigger and heavier cuts.
It plays a crucial role in chip formation, tool life, cutting forces, and surface finish. Understanding the influence of the relief angle and selecting the appropriate one can greatly enhance machining performance, productivity, and the quality of the finished product.

All turning inserts have a unique ISO code that contains various letters and numbers – believe it or not, these actually mean something! From just looking at the ISO code you can figure out the insert’s shape, relief angle, tolerance, cross-section type, cutting-edge length, thickness, radius, and chip breaker!
The chip breaker is represented as 2 letters in the ISO code. The chip breaker affects the cutting resistance, if the cutting resistance is low, it can avoid chipping and fracturing of the cutting edges. Reduced cutting resistance can also decrease the tool load and heat built up. The chip breaker also determines the depth of cut the insert can take, if you are not applying the correct depth of cut then you won’t be activating the chip breaker, this can cause the swarf to build up and become stringy, some people refer to this as a bird’s nest.
