Item details

The TBH Pro II Drilling System is our top of the line drilling system for professionals. Its hand built in Idar-Oberstein, Germany by professional gemstone drillers for unmatched precision, volume, and durability.

We build this system on a Proxxon bench top drill press and incorporate the same technology found in our Multidrill System. What set the TBH Pro II system apart is that the mechanics of the Multidrill system are moved inside the Proxxon drilling unit. This results in a shorter distance between the chuck and the end of the drill bit, which increases bit stability and results in less runout for better precision. Additionally, the drill spindle of the machine is drilled through, so the drill can be cooled with the coolant through the spindle from the top instead of the side.

The drill has a very powerful 220 - 240 V-permanent-magnet-motor and a spindle drive via a 3-time band pulley with poly-V-bands. This gives the very important advantage of the almost 6-time torque in the lower speed range (for large drilling diameters). Also, incorporates a spindle sleeve- feed for delicate work and a practical drill-depth-display with an adjustable end stop, as well a precisely located drill spindle.
