Frequently asked questions
What threading capacity does the TM 30 BLO / R 1700 offer?
See "Threading capacity" in the technical table: typically from M3 to M30.
The capacity refers to mild steel. For stainless steel or hard materials, reduce the maximum diameter by 20-30%.
What type of spindle does it have?
See "Spindle taper" in the technical table.
Standard GT type spindles allow quick tool changes using tap holders. Check compatibility with the included taps.
Is the spindle speed adjustable?
Professional models offer continuous or multi-step speed adjustment.
Low speeds for large taps (>M20), high speeds for small taps and soft materials.
Does it have an articulated reaction arm?
Professional bench models have an articulated arm for quick workpiece positioning.
The articulated arm balances the weight of the head and reduces operator fatigue in repeated cycles.
What power supply does it require?
See "Voltage" in the table: typically 230 V single-phase for bench models, 400 V three-phase for industrial models.
Models with motors over 1.5 kW require a three-phase line. Check availability in the workshop.
