V-Blocks, precision metalworking jigs, are used to securely hold round rods or pipes during drilling and milling tasks. Made of steel or cast iron, they feature a rectangular design with a 90-degree channel rotated 45-degrees, forming a V-shaped top. A groove at the bottom of the "V" accommodates screw clamps for workholding; some models incorporate internal magnets for magnetic applications. V-blocks are typically sold in pairs.
