Note：
1. Drilling capacity will differ depending on air pressure supplied (standard pressure 0.5 MPa).
2. When processing materials other than resin with a small-diameter drill (below φ1mm), it is recommended to use the rotation speed 7,000 min-1 or less.
3. Standard attachments for Hydro Speed Regulator are RB-2430 for SFB model and RB-2460 for SFC model.
Please indicate if you would like an optional Hydro Speed Regulator.
4. The selection of models should be based on the shape of the work, material, machinability, tool diameter and material, rotation speed (cutting speed), etc.
5. To reach maximum output, it is necessary to advance more than 7 mm from the start position.
6. When using tools with a carbide drill and tool shank that are harder than general high-speed drills, please contact the nearest sales office.
