Hans 6" and 8" Diamond Disc and Laps is the perfect tool for the commercial cutter or serious hobbyist. Diamond top plates just 1.0mm thickness is easy to apply to backing plates. All diamond top plates can come with PSA, Magnetic and Without Backing. Diamond discs are available in a wide range of mesh sizes for rough grinding and fine grinding of all precious gem material applications include performing rough and fine grinding on faceting material plus general lapidary grinding when precision is required. A controlled concentration of diamond bonded onto a precision backing plate ensures consistent grinding and surface finishes. Diamond discs can put on a precision ground.
10 inch to 24 inch Diamond Magnetic Disk was a very rough diamond used for heavy removal of glass from surfaces. It will create significant edge chipping that will need to be cleaned up with a rough to medium grit diamond disk. Disks are magnet backed for easy application and removal on lap grinder wheel heads.
Hans Diamond Pattern Disks are an Electroplated Diamond Disk with a controlled dispersion of diamonds on the surface in a pattern. In order to maintain the longevity of the diamond disk, the StarLap disks precisely place the diamonds on the disk instead of using a random dispersion like our own electroplated diamond disks. This gives a consistent grind on your glass by controlling the spacig between the diamonds and allows a slightly longer lifespan on the disk as the diamonds maintain more space between them and support the glass less.
The standard is designed to exceed the most rigid requirements. The aluminum backs are ground flat and parallel to exacting standards. All standard discs are made with 100% diamond and bonded with a hard electroplated nickel. Comes with 1/2" arbor. Screwbacked discs also available.
Diamond Channel Faceting Laps
These discs have a uniquely shaped working surface of randomly interspersed islands. The resulting channels flush away debris and prevent the stone from pulling excessively on the lap. These are great for rough cutting facets and grinding cabochon backs.
Diamond Rippled Faceting Laps
The rippled diamond laps have a textured surface that allows more contact of the diamond surface because the debris is whisked away through the channels. Each rippled diamond top plate is professionally bound to an aluminum master lap.
