Standard vee blocks are used to support cylindrical stock so that it can be machined accurately.
Vee blocks for square or round stock
Some vee blocks can be used to hold square or rectangular stock in addition to round stock.
The clamps of these vee blocks have screw holes at both 90 degrees and 45 degrees to accommodate square and cylindrical parts.
Micro vee blocks
Micro vee blocks are used to support very small cylindrical stock.
Four-way vee blocks
Four-way vee blocks have four different sized vee channels for stock of varying sizes. As these blocks do not have clamping devices, some of their surfaces are magnetic to secure metal workpieces in place.
Magnetic vee blocks
Instead of clamps, parts are held in place on magnetic vee blocks by a strong magnetic force.For more information, see: What is a magnetic vee block?
Tilting vee blocks
Tilting vee blocks (or adjustable angle gauges) are used to position square stock at an angle before it is machined.The angle of the block is adjusted depending upon the needs of the user and is firmly locked in position.
