* Nickel Bond* 1.00" hole* The diamond disk in 45 grit is 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.* * Electroplated on fiberboard substrate with copper laminate for rust-free operation over the lifespan of the disk* Manufactured in U S A by a major manufacturer.
* Nickel Bond* 1.00" hole* The diamond disk in 80 grit is a rough grit diamond used for shaping and removal of glass with less edge chipping than a 60 grit.* Electroplated on fiberboard substrate with copper laminate for rust-free operation over the lifespan of the disk* Manufactured in U S A by a major manufacturer.
* Nickel Bond* 1.00" hole* The diamond disk in 100 grit is a medium grit diamond used for surface preparation levelling of glass pieces. Disks are magnet backed for easy application and removal on lap grinder metal wheel heads* Electroplated on fiberboard substrate with copper laminate for rust-free operation over the lifespan of the disk* Manufactured in U S A by a major manufacturer.
* 1.0" hole size.* Spacers for smaller size holes available.* The diamond disk in 140 grit is a medium-fine grit diamond used for small surface area grinding and as an intermediate step from a rougher diamond to a finer diamond on larger surface areas. Disks are magnet backed for easy application and removal on lap grinder metal wheel heads.* Electroplated on fiberboard substrate with copper laminate for rust-free operation over the lifespan of the disk.* Manufactured in U S A by a major manufacturer.
* Nickel Bond* 1.00" hole* The diamond disk in 270 grit is a fine grit diamond used after rough or medium grit diamond pads to prepare surfaces for pre-polish stage with a resin diamond Smoothing Pads. Disks are magnet backed for easy application and removal on lap grinder metal wheel heads.* Electroplated on fiberboard substrate with copper laminate for rust-free operation over the lifespan of the disk* Manufactured in U S A by a major manufacturer.
* Nickel Bond* 1.00" hole* The diamond disk in 325 grit is a fine grit diamond used after rough or medium grit diamond pads to prepare surfaces for pre-polish stage with resin diamond Smoothing Pads.
