The Made in Germany Best Magnetic Drilling Machine MAB 825 - Full performance and flexibility for structural steel engineering, plant construction and engineering. The advantages of the MAB 825 are > The classic of the large-size series – with MT 3, > For core drills with a cutting depth of 30 mm, 55 mm, 75 mm and 110 mm, > Suitable for twist drills, reamer chucks, countersinks and thread cutting systems.

The MAB 825 is also available in Automatic option under ProfiSPEZIAL category as model number MAB 825 V.

Premium advantages of MAB 825 magnetic drilling machine:

FRICTION CLUTCH – The MAB 825 magnetic drilling machine is equipped with friction clutch which helps in preventing tool breakage. When the cutter gets jam inside the material and can no longer rotate, then the friction clutch activates and stops the spindle rotation preventing from the cutter break.

REVERSIBLE MOTOR – A reversible motor is absolutely necessary to do perform tapping or thread cutting. Once the tapping is finished, with the reversible motor you can remove the taps at the entry of the holes, which helps prevent the threads to get damaged. A reversible motor is also useful for Right-hand as well as Left-hand taps.

TORQUE CONTROL –The special torque control on the MAB 825 best magnetic drilling machine helps operators to get the correct required power for performing drilling, tapping, reaming or countersink. For example, tapping operations require high power and low speed, this can be achieved with the MAB 825 heavy duty magnetic drilling machine.

SPEED CONTROL – This speed control helps the operator to get the exact speed required for the machine as per the cutting tool size or diameter. The BDS ProfiPLUS class magnetic drilling machines are equipped with Speed & Torque control potentiometer to help you get the exact RPM and also the required torque while drilling, tapping, racing or countersinking.

FULL WAVE CONTROL ELECTRONICS – A full wave control electronics makes it possible for the motor to deliver the same output as of idle motor even while drilling. The electronic control ensures continuous adaptation of the motor output to the load during drilling. The advantages are high performance at low speed and a steady sequence. If load peaks should be too high, the electronic torque control will be activated in order to prevent tool breakage and avoidable damage. An active contribution to employee safety with BDS machines.

MAGNET INDICATOR – This helps the operator to know if the machine magnet base is properly placed on the material or not. When the machine is not placed properly the LED indicator will glow and indicate the operator to place the machine correctly. The load configuration and the reserves of the electromagnet are exactly adapted for the performance of the respective magnetic core drilling machine. The user is informed by a visual control. LED Green: The magnetic adhesion meets the minimum requirements. LED Red: The magnetic adhesion is not sufficient, because it is reduced due to low material thickness or a coat of lacquer, forge scale or zinc or improper placing.

OVERHEAT PROTECTION – Due to overload or improper handling of the machine while drilling the machine may get heated and due to heat, the motor may get damaged. The BDS magnetic drilling machines protect the machine from overheat by shutting down the motor when the sensors senses overheat, this prevents in damaging of the motor. After the motor is shut down by the overheat protection, keep the machine idle for 30 seconds to 1 minute and then run the run the motor again without drilling. Run the motor for a minute and then start to drill again. This feature increases the machine service life as well as avoids accidents.

CARBON BRUSH WEAR INDICATOR – The carbon brush indicator on the BDS magnetic drilling machines solves this problem. When the carbon brush is ”about to” get worn out, this indicator glows a red light and informs the operator that soon he has to replace the carbon brushes. The indicator gives advance indications so that the operator can order new carbon brushes without stopping his work with the machine.

OIL BATH GEARBOX – The motor gearbox of the BDS magnetic drilling machines are made of an oil bath. The advantage of BDS oil bath gearbox is that, oil in cold or hot temperature is always in a liquid state, hence oil always provides lubrication to upper as well as lower gears, thus increasing the service life of the machine drastically.

COMPLETE INTERNAL CABLING – The BDS magnetic drilling machines have complete internal cabling. the motor cable running from motor to the housing is mounted inside the machine and not external. Due to no cable outside, there is no mishandling of the machine or no accidents due to the external cable coming in the way.

The MAB 825 is also available with a swivel base option as model number MAB 845.
