Magnum 4" V-Block

Machinery craftsmen use these Vee blocks to hold rods or rounded bars while they are being marked for drilling. You can also use these to support a piece of metal that is being marked with a surface gauge if an angle plate is not available. This can be done because of how accurately machined this Vee Block is. This is a staple in most metal working workshops. These blocks either come in 3 or 4" sizes.
