APEXX Brazed Sink Wheel – 1 x 2 in., #30 Coarse Grit, 5/8 in.-11
APEXX Brazed Sink Wheel – 1 x 2 in., #30 Coarse Grit, 5/8 in.-11
The APEXX Brazed Sink Wheel is a 1 x 2 in. brazed diamond wheel used to cut and true sink openings on an angle grinder, in #30 Coarse grit with a 5/8 in.-11 thread and 2 in. of diamond height. Ocean Diamond specifies dry or wet use with water recommended when possible, rates the 1 in. wheels to 6,500 RPM, and builds this line in a No-Bearing and a Top-Bearing form — this is the No-Bearing version. The grit scale on the brazed sink wheels runs #30 coarse, #70 medium and #140 fine.
Do not read the grit numbers against the APEXX Brazed CNC Sink Drums, which run a different scale entirely — #50 coarse, #100 medium, #200 fine — on a 1/2 in. Gas thread with a center water feed, wet use only. The two families are not interchangeable and their grit numbers do not line up. For the tightest corners the same wheel is made at 1/2 x 2 in., stocked here in #30, #70 and #140.

Fabricators cutting and truing sink openings by hand on an angle grinder, across engineered stone, granite, marble, porcelain and ultra-compact, where a coarse wheel is wanted to remove material fast before a finer pass.
Frequently Asked Questions
What size is this sink wheel?
1 x 2 in. — a 1 in. diameter with 2 in. of diamond height — in #30 Coarse grit.
What thread does it take?
The sink wheel takes a 5/8 in.-11 thread, on an angle grinder.
What is the grit scale on this family?
Ocean Diamond runs the brazed sink wheels at #30 coarse, #70 medium and #140 fine. The CNC sink drums use a different scale — #50, #100 and #200 — so the numbers do not compare across the two families.
What is the difference between No-Bearing and Top-Bearing?
Ocean Diamond builds both. A top bearing rides the underside of the slab and holds the wheel at a set depth; a no-bearing wheel is guided by hand. This is the No-Bearing version.
Does it need water?
Ocean Diamond specifies dry or wet use and recommends water when possible.
How fast can it run?
6,500 RPM maximum for the 1 in. wheels; the 2 in. wheels in the same line are rated to 4,000 RPM.
