RUKO LOS-HM 68 mm serra copo de metal duro para alvenaria e betão

Drilling large-diameter holes in masonry, concrete, and brick with a standard hole saw often leads to rapid tooth wear and poor cut quality. The RUKO LOS-HM 68 mm hole saw solves this by combining a tungsten carbide cutting edge with an optimized tooth geometry, delivering clean cuts and long service life in abrasive materials.

Who is it for

This hole saw is intended for professionals and serious DIYers who need to create precise openings in masonry, concrete, brick, aerated concrete, sand-lime brick, plasterboard, and non-abrasive tiles. It is suitable for use with rotary drills and hammer drills in rotary mode.
