Whether you’re grinding, drilling, or milling, sometimes a simple V-block isn’t enough to hold your workpiece steady. That’s where a V-block and clamp set would really come in handy — they’re usually sold in pairs like this Series 278 set from Starrett.
Starrett makes the 1-1/4″ square by 1-5/8″ long blocks from steel then hardens and grinds them to extreme accuracy. They number and match the set so the vees are always in alignment with each block, as well as central, parallel, and square with the ends and sides. They tap a 1/4″-20 hole in the side for attaching the block to a piece of angle iron. When you need more leverage than the knurled clamp screws can provide, there’s a hole to make an impromptu T-bar.
Starrett’s V-Block and Clamp Set can run you anywhere between $100 and $200. If you’re looking for a cheaper alternative, Micro-Mark sells a similar pair for $44. You’re probably not getting the same quality, but depending on the work you’re doing you might not need it.
