The EASYGRES drill bit kits are the most economical solution for users who need to carry out drilling, with different diameters and in any type of ceramic tile. The EASYGRES range are electroplated diamond drill bits for wet cutting, suitable for use with a non-percussive power drill. The quality of the diamond used in the design and manufacture of EASYGRES drill bits allows the drilling of stoneware, porcelain tiles, granite, marble and glass. RUBI offers the building professional different product kits with configurations tailored to the most common situations. For smaller diameters (6-12 mm), RUBI offers the practical EASYGRES kit consisting of: one or more drill bits (depending on the model), the practical EASYGRES guide, the corresponding centring bushings (depending on the number of bits contained in the kit) and fastening adhesives. The EASYGRES guide allows you to make holes in both the ground and the wall, thanks to the functional design of its water tank that includes a flow control valve. The guide is easily attached to any surface, thanks to its renewable adhesive system. In addition to these practical kits, RUBI also offers the EASYGRES PLUS kit consisting of: 7 EASYGRES drill bits (20, 28, 35, 43, 50, 68 and 75 mm diameter), a MULTIDRILL centring guide, a tank and hose unit and a practical case. Finally, and thinking of the most common use of these types of drill bits, we have the EASYGRES 35 mm kit. This kit offers the possibility of acquiring the most widely used drill bit diameter (35 mm) along with all the necessary accessories: MULTIDRILL guide and tank and hose units. The average life of the EASYGRES drill bits varies according to the diameter, in 6-12 mm EASYGRES the average life is 10 holes and in 20-120 mm EASYGRES the average life is 25 holes. The average life of the drill bits ALWAYS depends on the type of material, its thickness and proper cooling and use. The drilling depth of EASYGRES drill bits is 25 mm. The EASYGRES drill bits have a lateral opening which improves the cooling of the drill bit and facilitates the removal of solid residues after each drilling. Before further drilling we must ensure that the drill bit is clean and free of any obstruction. The recommended speed for use of EASYGRES drill bits is between 400 and 1000 rpm, depending on the material being drilled. For a better finish and longer drill bit life, it is important to respect the proper rotation speed and exert moderate pressure during drilling.
