APEXX Brazed CNC Sink Drums – Coarse, 50 Grit
The APEXX Brazed CNC Sink Drum in Coarse 50 grit is a vacuum-brazed drum for shaping sink cutouts on a CNC, built with a single brazed layer of diamond on a 1/2 in. gas thread. Coarse 50 is the first rung of the APEXX brazed drum ladder, which also runs 100 grit medium and 200 grit fine.
The working diameter of this listing is being confirmed and is not published here: two internal records disagree on whether this part number is the 1/2 in. or the 3/4 in. drum, and both sizes exist in the manufacturer's range. Since a drum of the wrong diameter will not finish a cutout dimensioned for the other, buyers who need a confirmed 1/2 in. drum at this grit should order the APEXX Brazed CNC Sink Drum listed as 1/2 x 2 in., #50 Coarse Grit instead of this listing.

Frequently Asked Questions
What grit is the coarse APEXX brazed sink drum?
50 grit. The APEXX brazed sink drum range runs 50 grit coarse, 100 grit medium and 200 grit fine.
What thread does the drum use?
A 1/2 in. gas thread, which is the standard thread across the APEXX brazed CNC sink drum line.
What does brazed mean on a sink drum?
The diamond is held in a single brazed layer on the drum's surface rather than in bonded segments, which is what lets a brazed drum cut aggressively from the first pass.
What diameter is this drum?
The diameter on this listing is being confirmed with the supplier and is not published here. If your cutout needs a confirmed diameter, order a listing that states one — the catalogue carries the APEXX brazed sink drum in a confirmed 1/2 x 2 in. at this same 50 grit.
