84mm Diamond Hole Saw – Vacuum Brazed Bit for 75mm Pipe Holes in Tile, Granite & Stone

The Castle Tools SA 84mm diamond hole saw gives a snug, professional fit around 75mm pipes — soil, vent and stormwater lines — through porcelain, ceramic, granite and marble. Vacuum-brazed diamond cuts the full diameter cleanly, so plumbers and tilers across South Africa avoid the oversized, chipped holes that make a bathroom look unfinished.

• Vacuum-brazed diamond for hard porcelain and natural stone
  
• Dry or wet cutting; wet recommended in thick granite
