Bohrmaster
The journey of BOHRMASTER machines began with the very first creation: the BHM35. Born from the understanding that many metal professionals simply seek efficient hole drilling, the BHM35 quickly earned its place in the industry. Now it is time for the next generation!
Namely, the renewed BOHRMASTER BHM35: just as powerful, efficient and 27% lighter! And even more important, after many requests, we expanded the range with a 50 mm & 100 mm capacity machine: the BHM50 and BHM100, each with their own features and benefits.
Weighing only 8.5 kg or 18.7 lbs, this little powerhouse stands out as it is 27% lighter than its predecessor. But make no mistake, its lightweight design doesn’t compromise on strength! Witness the BHM35 effortlessly drilling through various metals with finesse. From holes to countersinking tasks, this magnetic drilling machine masters them all, handling diameters of up to Ø 35 mm or 1 3/8 inches with ease!
Experience top-notch performance and efficiency in a compact package – the BHM35, where strength meets finesse, and small size conquers big tasks!
Experience true freedom with BHM50, delivering rapid and pristine results – just the way you prefer. This dependable, lightweight machine is an indispensable addition to any workplace. Versatility is its forte, excelling in drilling and countersinking tasks up to Ø 50 mm or 2 inches in diameter! Its Morse Taper 2 spindle makes switching between drilling jobs a breeze.
Embrace the BHM50 and redefine productivity in your workplace today!
Unleash the power of the mighty BHM100 – a true heavy duty machine at only 28 kg or 61.7 lbs. Witness how it expertly cuts holes without effort up till Ø 100 mm or 4-inch diameter in record time. This magnificent machine boasts not only unparalleled strength but also exceptional efficiency, making it a standout in its class. Its Morse Taper 3 spindle makes switching between drilling jobs a breeze. What also makes this machine unique, is its ability for tapping!
When it comes to economic superiority for this kind of work, there’s simply no competition for the BHM100. Embrace perfection with this exceptional magnetic drilling champion!
