Choosing between VESSEL’s two threaded-rod deburring bits involves more than weight. The 36 g A20ZB55C is the version without a nut-driving ring; the 43 g A20ZBN55C includes that function. Nut feeding requires the latter model or the separate ZN23 ring fitted to the base bit.
VESSEL’s September 30 notice scheduled shipments for October 2. That date has passed; this report does not establish that any particular retailer has stock now. The current product listing includes the two bits and the separate ring.
Keep body and cutting material distinct
The manufacturer specifies three carbide cutting edges, describing tungsten as their principal constituent, and an aluminium-alloy body. It lists stainless-steel and iron threaded rod in W3/8, W1/2 and M6–M16 sizes. Both bit models are 56 mm long, but their listed weights differ because the 36 g figure excludes the ring.
VESSEL’s company profile dates its founding to August 1916. That background supplies company history, not proof of the performance or manufacturing origin of these particular bits. No hands-on test has been conducted for this report.
