APEXX Brazed CNC Sink Drum – 1/2 x 2 in., #50 Coarse Grit, 1/2 Gas
The APEXX Brazed CNC Sink Drum is a 1/2 x 2 in. brazed diamond drum used to cut and true sink openings on a CNC, in #50 Coarse grit with a 1/2 in. Gas thread and a center water feed. Ocean Diamond specifies wet use only, and notes that these are also known as brazed finger bits and sink wheels. The grit scale on the CNC sink drums runs #50 coarse, #100 medium and #200 fine.
The grit numbers on this family do not compare with the APEXX Brazed Sink Wheels, which run #30 coarse, #70 medium and #140 fine on a 5/8 in.-11 angle-grinder thread. This is the CNC tool: 1/2 in. Gas, center water feed, wet only. Running it dry will burn it.
