1. The selection of models should be based on the shape of the work, material, cutting characteristics, diameter and material of tools, rotation speed (cutting speed), etc.
2. The drilling capacity displayed in the above table is based on values representing a drilling depth of two times the diameter of the drill.
3. The standard attachment for the hydro speed regulator is RB-3140. Please specify an optional Hydro Speed Regulator if required. (Optional Hydro Speed Regulator Models: RB-3160, R-3180A)
4. Maximum weight of the attachment that can be mounted when machining downwards is 15 kg.
5. 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.
