A suitable toolholder with outside cooling in wich the Drabus frictiondrill is concentrally chucked, is necessary to prevent the generated friction heat from reaching the bearings of the drill spindle.

To clamp the Drabus frictiondrill into the toolholder, advice an ER collet with a conical form.

Nut

Off course, you need a Drabus frictiondrill Those are classified in groups according to their form.

In combination with a Drabus frictiondrill, it is possible to use a formtap for thread forming.
(for thread cutting are there also Drabus frictiondrills)

Lubricate the Drabus Frictiondrill with VTP-paste when frictiondrilling in steel, and with VTF-fluid when frictiondrilling copper and brass. The VTP- and VTF-lubricant is heat resistant up to 1100°C. Other materials require proper lubricant to friciondrill in optimal conditions (to be specified in advance of the application).

TIP: We suggest a rigid column drilling machine or a drilling unit with a suitalbe speed range and sufficient motorpower. By new investment, we advise a frictiondrillingmamchine with a hydro-pneumatic control of the frictiondrilling cycle. Please contact us for more information.
