1. The selection of models should be based on the shape of the work, material, cutting characteristics, diameter and material of tools, rotational speed (cutting speed), etc.
2. The drilling capacity displayed in the above table is based on values representing a drilling depth of twice the diameter of the drill.
3. The RB-3160 comes standard with a Hydro Speed Regulator. A Hydro Speed Regulator is available as an option upon request.
(Optional Hydro Speed Regulator models are: RB-3140, R-3182A, and R31132A)
4. Make sure to use a collet chuck or spindle nose when the hardness of carbide drills and tool shanks is higher than that of general HSS (high-speed steel) drills.
5. Valveless specification is standard. If you require valve block specification (former standard specification), please order valve block ass'y separately.
(Replacement to be made by customer)
