Face grooving with boring tools is generally more efficient than milling with circular interpolation, especially when manufacturing grooves of large diameters. Also, whenever a surface for a sealing application is required, there is no other acceptable or accurate option than to use a face grooving setup.

Strength and Economy: Square inserts offer a very strong 90° corner, providing excellent economy with up to 8 cutting edges on double-sided inserts. Best For: These inserts are ideal for rough facing operations, particularly on castings, forgings, and rough-sawed blanks. Limitations: Square inserts are unable to turn or face up to a shoulder unless used in a toolholder with a minimum 5° lead angle. High radial forces can push against the workpiece during turning, so they should always be used in a stable setup.

Intricate Machining: The 35° diamond insert is the go-to choice for intricate shape copy turning and can “in-copy” at angles up to 49°. Best For: It is ideal for working extremely close to the tailstock or live center. Limitations: This is the weakest insert shape in terms of edge strength, so the depths of cut and feed rates must be lighter. It also has the highest cost per edge.

When machining, selecting the correct carbide insert shape is crucial for optimizing performance, tool life, and achieving the desired results. Each insert shape has its unique strengths and applications. Here’s a guide to help you choose the suitable carbide insert based on your specific machining needs, using information from Millstar’s Total Carbide Insert Solutions.

Experience face grooving innovation like only BIG DAISHOWA can provide. Simply swap out the standard insert holders with the grooving ones, load in the carbide grooving inserts, set the diameter and you are good to go. Face grooving insert holders are also available for our EWN and 112 series boring heads for more precise applications. Grooving inserts are also available for our EWN and 112 series heads for more precise applications.

Choosing the right insert shape is critical to the success of your machining operation. By understanding the strengths and limitations of each insert shape, you can optimize your machining processes for better efficiency, accuracy, and cost-effectiveness.

Versatility: Triangle inserts are highly versatile and suitable for turning, facing, boring, copy turning, and basic profiling. Best For: They are an excellent choice for general boring due to their stable seating in the boring bar pocket and extra side clearance, which reduces the risk of chip jamming. Limitations: The edge strength of triangle inserts is weaker than 80° diamond-shaped inserts.

Profile Turning: The 55° diamond insert is generally the first choice for profile or copy turning applications, capable of “in-copy” (plunge turn into a smaller diameter) at a 30° angle. Best For: These inserts are ideal for machining near the tailstock or live center. Limitations: They have weaker edge strength than triangle inserts, and the cost per edge is higher than most other turning inserts.

Economy: This insert offers increased economy compared to CNMG-style inserts. Best For: These inserts are typically used for moderate cut and feed rate depths, making them a good choice for general-purpose machining. Limitations: The seating is not as stable as CNMG-style inserts, and they cannot handle as deep a depth of cut.

Versatility and Popularity: The 80° diamond insert is the most popular shape due to its versatility. It has a strong cutting edge and secure seating in the insert pocket. Best For: These inserts are suitable for turning and facing operations, with opposite 100° corners providing maximum economy in roughing applications. Limitations: With only 5° of clearance between the trailing side of the insert and the workpiece, chip jamming can occur when boring.
