Seco Tools has introduced its R217/220.28 cutters with new body designs that incorporate double-sided round inserts to deliver cost-effective performance, as well as boost productivity. Double-negative-positioning pocket seats of the R217/R220.28 cutters deliver enhanced cutting capability and significant gains in productivity, according to the company. These pocket seats also enable safe and user-friendly indexing to save time and provide trouble-free operation.
The R217/R220.28 performs facemilling, slotting and contouring in ISO M and ISO S materials, as well as some difficult-to-machine ISO P materials, such as martensitic stainless steel. The cutter excels in Z-leveling applications and is ideal for machining turbine blades for the aerospace and power generation segments.
The range for R217/220.28 includes diameters from 1.25" (32mm) to 4.00" (100mm) in normal and close pitch versions. The 12mm IC inserts are available in PVD and CVD grades with two different geometries for varying applications.

- chemical vapor deposition ( CVD)
chemical vapor deposition ( CVD)
High-temperature (1,000° C or higher), atmosphere-controlled process in which a chemical reaction is induced for the purpose of depositing a coating 2µm to 12µm thick on a tool’s surface. See coated tools; PVD, physical vapor deposition.
- facemilling
facemilling
Form of milling that produces a flat surface generally at right angles to the rotating axis of a cutter having teeth or inserts both on its periphery and on its end face.
- inscribed circle ( IC)
inscribed circle ( IC)
Imaginary circle that touches all sides of an insert. Used to establish size. Measurements are in fractions of an inch and describe the diameter of the circle.
- physical vapor deposition ( PVD)
physical vapor deposition ( PVD)
Tool-coating process performed at low temperature (500° C), compared to chemical vapor deposition (1,000° C). Employs electric field to generate necessary heat for depositing coating on a tool’s surface. See CVD, chemical vapor deposition.
- pitch
pitch
1. On a saw blade, the number of teeth per inch. 2. In threading, the number of threads per inch.
- slotting
slotting
Machining, normally milling, that creates slots, grooves and similar recesses in workpieces, including T-slots and dovetails.
