Description
This is the Grace USA SP-21-BB bench block, the neoprene tool holder built to keep the SP-21 21-piece steel punch set in line on your workbench. It is the holder by itself, not the punch set, so grab this if yours went missing, got chewed up over the years, or if you bought the punches loose and want a proper home for them. Every punch drops into its own dedicated slot, which beats digging through a drawer or a coffee can when you are halfway through a project and need the next size up.
What the SP-21-BB Bench Block Is Made Of
Grace makes this block out of 60 durometer neoprene rubber, and that choice matters more than it sounds. Neoprene handles oil and solvents without breaking down, so the gun oil and cleaning chemicals living on most benches will not eat it up. It also stays stable across a wide range of temperatures and does a nice job soaking up vibration, which keeps things from bouncing around while you work.
Why the SP-21 Bench Block Earns Its Spot
The whole point here is organization you can trust. Each slot is sized for a specific punch, so you always know where the 1/16 roll pin punch lives versus the center punch, and everything stays visible and within reach. For anyone who moves between roll pin punches, short roll pin punches, and standard gunsmith punches on a regular basis, having them laid out in order saves real time and keeps you from grabbing the wrong one mid task.
Grace USA has been turning out gunsmithing tools in the United States since 1941, and this bench block is handcrafted right alongside the rest of the line. It is a simple piece of kit, but if you already run Grace punches, it is the natural companion that keeps your setup tidy and ready to go.

Frequently Asked Questions
Does the SP-21-BB bench block come with the punches?
No, this listing is for the bench block holder only. It is the neoprene organizer designed to hold the Grace USA SP-21 21-piece punch set, but the punches themselves are sold separately. Pick this up if you need a replacement holder or bought your punches without one.
What is the Grace USA bench block made of?
It is molded from 60 durometer neoprene rubber. Neoprene resists oil and shop chemicals, dampens vibration, and stays stable across a wide temperature range, which makes it a smart material for a workbench that sees plenty of solvents and gun oil.
Will this bench block fit punches other than the SP-21 set?
The slots on this block are sized specifically for the punches in the Grace USA SP-21 set. Other brands or different Grace sets may not seat correctly, since Grace makes a dedicated bench block for each of their tool sets. If you run a different set, look for the matching bench block for that model.
Where is the Grace USA SP-21-BB bench block made?
It is handcrafted in the United States. Grace USA has been building gunsmithing tools domestically since 1941, and their bench blocks are made right alongside the punches and screwdrivers they are designed to hold.
