Type: 90-degree V-Blocks with added transverse (cross) vee-grooves. • Function: The standard longitudinal V-groove holds long cylindrical workpieces parallel to the block. The cross-groove (the horizontal "V" crossing the main one) allows you to securely hold parts perpendicular to the block, which is essential for center-drilling through the side of a rod. • Condition: These appear to be used, hardened steel blocks with some surface oxidation/staining. They feature threaded holes on the sides and base for mounting to a machine table or angle plate. • Design: The stepped grooves on the sides are intended for clamps
