The working material in DRYGRES 4DRILL drills is deposited using a vacuum deposition method, which increases heat and friction resistance.
DRYGRES 4DRILL drill bits are available in diameters from 6 to 20 mm. They are ideal for drilling mounting holes in bathrooms and for mounting accessories and decorative elements.
DRYGRES 4DRILL drills are designed for use on electric drills or screwdrivers. The hexagonal chuck fits into any drill on the market.
The average service life of DRYGRES 4DRILL drills is 15-20 holes, but ALWAYS depends on the diameter of the drill, the type and thickness of the material and the use of appropriate cooling techniques.

The maximum drilling depth with DRYGRES 4DRILL drills is 36 mm.
All DRYGRES 4DRILL drill bits feature a wax insert. The wax melts while the drill is in use and aids cooling and facilitates the removal of fragments of the drilled material. Once the wax has completely melted the drill bit can still be used, only complete wiping of the diamond indicates the end of the drill bit's life.
The minimum recommended operating speed for DRYGRES 4DRILL drills is 2500 rpm.
A better finish and life of the drill is achieved by maintaining the correct working speed of the drill, making the correct orbital movement during drilling and, after drilling, making sure that no debris remains in the centre of the drill.
