SERIES OVERVIEW
R390 Precision Indexable Cutter Bar
The BOFA R390 precision cutter bar series uses R39011T308 indexable inserts. Models are selected by shank diameter, cutter diameter, overall length and two-edge cutting configuration.
Standard configuration
The supplied range covers shank sizes C15 to C32, cutter diameters D15 to D35 and overall lengths of 150 or 200 mm. Refer to the full model and size chart below for individual configurations.
Selection support
Tell BOFA the material, required cutter diameter, overall length and machine interface for a compatible R390 recommendation and quotation. Inserts are supplied separately.
ENGINEERING DATA
Selection data for a technical quotation.
Use the published chart and series attributes where available. For a safe recommendation, send the fields below; BOFA will return the matching geometry, insert and cutting-condition card for your machine.
| Decision field | What to provide or verify | BOFA quotation output |
|---|---|---|
| Published series attributes | R39011T308 Inserts · D15-D35 mm · C15-C32 mm · 2T Edge Count | Confirm the exact model and size chart row |
| Workpiece material and hardness | Exact grade plus measured HRC or HB; include stainless, cast iron, aluminium or mould-steel condition | Recommended grade, geometry and coating |
| Speed, feed and depth | Target RPM or cutting speed, feed units / fz / Vf, axial ap and radial ae | Condition card for the selected diameter and operation |
| Geometry and reach | Diameter or ball radius, flute count, cutting length, overall length, helix and coating | Compatible standard or custom configuration |
| Insert and interface | For indexable tools: body model, insert code, screw and wrench. For solid tools: spindle taper, shank, holder and gauge length | Compatibility check before ordering |
| Tolerance and runout | Required tool-tip runout and diameter / length tolerance | Achievable value confirmed on drawing or datasheet |
| Cooling and maximum engagement | Dry, air blast, MQL or flood coolant with pressure / flow; state required machining depth | Safe engagement guidance; do not infer a limit from cutting length alone |
