Button Inserts
Round inserts have a strong cutting edge, making them an excellent choice for many applications, including:
- Mold cavity and core roughing
- Roughing of complex part contours
- Helical interpolation (larger-diameter hole making)
- Pocketing
- Semifinishing
- Copy milling
- Face milling

Square Inserts
For sizes: R4 (1-1/4" diameter and above only)
Your Toroid cutter can be used for the most common applications involving 90° milling. Utilize the more economical 4-sided inserts for:
- Profiling
- Step milling
- Face milling
- Slotting
- Helical interpolation (cored holes only)
- Plunge milling

Octagonal Inserts
8-sided geometry is excellent for general face milling. 45° lead angle provides increased feed capacity for:
- Face milling
- Profiling
- Helical interpolation
- Chamfering
Each of the 8 usable edges comes with an integral wiper flat for outstanding surface finishes (RHINO-CARB only).
