MINIGRES diamond tips are ideal for drilling stoneware tiles, porcelain tiles and pieces of granite and marble.

The MINIGRES kit is the perfect solution for installation of accessories and decorative extras.

It consists of the following: a swivel coupling, a MULTIDRILL centring guide, three 15/64, 5/16 and 3/8 in. drill bit tips (one for each diameter), a drill head with a 1/2" thread and a practical case.

The diamond rim of MINIGRES tips is sintered and joined to the drill bit body by laser welding.

MINIGRES diamond tips must ALWAYS be used water-cooled and with a non-percussive power drill.

The use of the drill HEAD with a 1/2" thread (ref. 04937) and SWIVEL COUPLING. (ref. 50907) is essential for proper cooling of the diamond tips.

When you have to drill to make wall plug enclosures, it is recommended to only drill the wall lining material (ceramic tile, natural stone, etc.) and to finish the drilling for the plug with a twist drill bit.

The average life of the MINIGRES diamond tips is 40 holes and ALWAYS depends on the type of material, its thickness and proper cooling and use.

The drilling depth of MINIGRES diamond tips is 1-3/8 in.

The MINIGRES diamond tips have no side opening for solid waste disposal, so before making a new hole you must ensure that the drill is clean and free of any obstruction.

The maximum speed of use for MINIGRES tips is 1200

For a better finish and longer drill bit life, it is important to respect the proper rotation speed and exert moderate pressure during drilling.
