Sapphire Burnisher


Our most superior pivot polisher is our sapphire burnisher. This sapphire tool is suitable for polishing and fine burnishing of fine parts such as pivots, shafts, probes and pins made from hard steel, carbide and ceramic to a glass finish. Each burnisher/deburring tool has a very slight burnishing grain that can be exaggerated with the use of a fine diamond file.

These Sapphire Burnishers are a real professional tool and the feedback has been tremendous. If you want immaculate pivots then this is the tool for you.

  • Delicate burnishing and de-burring of soft and hard materials
  • Superior to hardened steel, carbide and ceramic.
  • Precision ground Sapphire mounted in a hexagonal aluminium holder, so no rolling off your bench!

"The Sapphire Burnisher, it's not just a tool - it's a wizards wand! Back in the middle ages you'd have been burned at the stake for making such products" - Ketil Blaasvaer
"The sapphire burnisher is magic! I can now make brilliant pivots with little effort. The cap now never comes off the burnisher end of my old combined steel file/burnisher" - Terry Hunt
"Before purchasing a sapphire burnisher I used a conventional steel burnisher with good results however the sapphire has always provided a superb finish better than I could ever achieve with the steel" - G.M. Cardew
