Collet Block, ER-25 Square

A collet block is a precision workholding device designed to securely grip and position cylindrical or hexagonal workpieces. Unlike traditional vises that clamp with flat jaws, collet blocks utilize a collet – a slotted sleeve with a tapered outer surface – that collapses uniformly around the workpiece when tightened. This provides a concentric and consistent grip, minimizing the risk of distortion or damage, particularly when working with delicate or thin-walled materials.

• Os collets ER-25 têm um intervalo de aperto de 1/16" a 5/8" (1,0 mm a 16,0 mm).
• Este bloco de collet oferece indexação fácil para 2 e 4 divisões.
• The collet block is 1.48" square and the body is 2.7" long.

The collet block itself is typically a hardened steel block, often square or hexagonal, with a precision-machined bore to accommodate the collet. The combination of the precision collet and the stable block creates a rigid and accurate platform for a wide range of machining operations.
