Diamond Core Bit RS-TX 1 1/4 72mm x 450mm

Drilling large-diameter holes in reinforced concrete or masonry can quickly dull inferior bits, causing slow progress and excessive wear. The Diamond Core Bit RS-TX 1 1/4 72mm x 450mm solves this with laser-welded diamond segments and a robust steel barrel, delivering fast, clean cuts in demanding professional applications.
