Bernardo Electric Tapping Machine TM 12 BLO / R 1100
The Bernardo Electric Tapping Machine TM 12 BLO / R 1100 is a compact, high-performance machine for tapping threads from M3 to M12 in steel, stainless steel, aluminum, and non-ferrous metals. Equipped with a micro-spray system for optimal cooling with minimal coolant consumption and a blowing device that keeps the work area clean and visible, it guarantees precision and safety. The articulated arm with an operating radius of 1100 mm ensures great flexibility, while the motor unit, tiltable between 0° and 90°, allows tapping in any position. The quick-change chuck with integrated safety clutch protects taps from accidental breakage. With a variable speed of 150 to 600 rpm, a 600 W, 230 V motor, a touchscreen with digital depth indication, and a low weight of 22 kg, it is the ideal choice for workshops, maintenance departments, and metalworking shops.

Frequently Asked Questions
What is the difference between TM 12 and TM 24?
The TM 12 taps from M3 to M12 with a 600 W motor and speeds of 150–600 rpm — for standard tapping in workshops, maintenance departments, and metalworking shops. The TM 24 taps from M5 to M24 with a 1,200 W motor and speeds of 70–200 rpm — for large diameter threads requiring higher torque. The TM 24 is slower but more powerful. The choice depends on the maximum diameter of the holes to be tapped: M12 covers 90% of standard applications, M24 is necessary for heavy metal structures.
What do BLO / R in the name mean and what do they include?
BLO indicates the micro-spray system (Blowing/Lubrication Oil) for automatic cooling and lubrication during tapping — minimal coolant consumption compared to traditional flood systems. R indicates the blowing device for chip removal. The final number (1100, 1500, 1200) indicates the operating radius of the articulated arm in mm.
Does the quick-change chuck protect taps from breaking?
Yes — the integrated safety clutch in the DIN quick-change chuck trips when the torque exceeds the set value, stopping rotation before the tap breaks. The tripping torque is adjusted based on the tap diameter and the material to be tapped. It is the component that most reduces the risk of breaking expensive taps in tough materials like stainless steel and high-strength steels.
What materials does the TM BLO series work on?
Steel S235 and S355 — without problems up to maximum capacity. Stainless steel AISI 304 and 316 — reduce speed to 50–60% and increase coolant concentration. Aluminum — maximum speed with specific cutting oil for aluminum. The stated maximum material resistance is 400 N/mm²; for high-strength steels (over 600 N/mm²), check with Krollit.
