Parlec EXT100 Collet Chuck

Parlec EXT100 Collet Chuck — 1" diameter, 1.83" projection, 7.28" overall length (OAL) — is a compact toolholding accessory designed to secure round tool shanks in machine-tool setups. The EXT100's measurements establish its footprint within toolholding assemblies and influence clearance with adjacent tooling in tool changers or spindles. With a 7.28" OAL and a 1" diameter, the unit fits into configurations intended for small-diameter tooling within compatible holders, while the 1.83" projection specifies the distance from the chuck face to the tool end. This combination supports use in milling, drilling, or other material-removal tasks where space is limited and a rigid interface between tool and spindle is desirable. As a Parlec product, the EXT100 is part of Parlec's range of collet chucks intended for use in workshop and production environments. When selecting this component, verify that its form factor aligns with your machine's toolholding system and that the overall length fits within your available space in the tool array.
