Rubi Broca Drygres Premium 8 mm

The DRYGRES PREMIUM range of diamond drill bits is perfect for drilling all types of ceramic tiles, especially porcelain stoneware, and other covering materials such as marble and granite.

RUBI has used VACUUM BRAZED vacuum welding technology in the DRYGRES PREMIUM range of drill bits, which increases resistance to temperature and friction, to fix the diamond particles to the cutting area.

DRYGRES PREMIUM drill bits, with diameters Ø 6 to 12 mm, are perfect for placing bathroom accessories or any type of decoration accessory on ceramic surfaces. The rest of the diameters of the range of DRYGRES PREMIUM diamond drill bits, from Ø 20 to 85 mm, have been designed mainly so that the ceramic tile setter can obtain the best results when making the necessary holes for taps. water, drains, light points, etc.

DRYGRES PREMIUM diamond drill bits are dry cutting and can be used, thanks to their M14 thread connection, directly with a grinder or with a hammerless electric drill, by using the drill adapter (ref. 05976).

The average life of DRYGRES PREMIUM drill bits varies depending on the diameter: in those from Ø 6 to 12 mm the average life is 60 holes and in DRYGRES from Ø 20 to 85 mm the average life is 150 holes.

The average life of drill bits ALWAYS depends on the type of material, its thickness and correct cooling and use.

The drilling depth of DRYGRES PREMIUM drill bits is 30 mm for drill bits from Ø 6 to 35 mm and 38 mm for drill bits from Ø 43 to 85 mm.

In diameters Ø 6, 8, 10 and 12 mm, DRYGRES PREMIUM contains wax inside. This wax melts during use of the drill bit and facilitates cooling and evacuation of drilling debris (If the wax runs out, the drill bit can continue working. Only the total loss of the diamond indicates the end of the life of the drill bit. drill.).

The DRYGRES PREMIUM drill bits (diameters Ø 20 to 85 mm) have a side opening that improves the cooling of the drill bit and makes it easier to remove solid waste after each drilling. Before drilling a new drilling, we must ensure that the drill bit is clean and free of any obstruction. Drill bits from Ø 43 mm are segmented to improve stability during drilling.

The maximum speed of use for DRYGRES PREMIUM diamond drill bits is 14000 r.p.m.

For a better finish and longer life of the drill bit, it is important to respect the appropriate rotation speed and perform a slight orbital movement throughout the drilling.
