• 6 Inch Disc, 1/2 Inch Arbor: Rigid solid steel base fits standard flat lap machines, faceting machines and slant cabbers.
• Sold Individually: One 240 grit disc per pack. Other grits from 60 to 1500 are available separately.
• Tool Sharpening: Also hones knives, scissors, chisels and other metal tools.

• Materials: Gemstones, glass, rocks, stone, granite, marble and metal tools.
• Machine Compatibility: Flat lap machines, faceting machines and slant cabbers that take 6 inch discs with a 1/2 inch arbor.
• Note: This disc is coated on one side only.

• Mounting: Clamp the disc to your lap machine or master lap using the 1/2 inch arbor, coated side up.
• Break-In: Run the disc on scrap material for a short break-in before working on finished pieces.
• Keep It Wet: Use a steady water drip to cool the piece, carry away grinding residue and keep the grit from clogging.
• Work Through the Grits: Step from coarser to finer grits; 240 grit is used for smoothing between shaping and polishing.
• Light Pressure: Let the diamonds do the work. Heavy pressure or running dry wears the coating faster.

A: It fits flat lap machines, faceting machines and slant cabbers that take 6 inch discs with a 1/2 inch arbor.
Q: Should I use it wet or dry?
