17) Multirange Collet T-285 2.1/8 - 2.1/4in E85

The range includes all European standard DIN 6343 Auto Multibore Collet types.

Multibore Collets have a 1/8" gripping range. DIN 6343 Auto Multibore Collets have a 2mm gripping range. The two types are not interchangeable within the same chuck configuration.

The main advantage of Multibore Collets is their ability to maintain a parallel grip over the entire closure range. Multibores are not specific to a bar stock or material size. By holding a minimum inventory of standard collets, immediate availability of collets can be provided for non-standard diameter material.

Components must occupy a minimum of 67% of the collet length (front). Crawford Multibores are supplied with a plain bore as standard and can alternatively be supplied in the "Heavy Duty" configuration for holding black bar or for operations involving very heavy machining.

Multirange collets are a British made direct equivalent of the Multisize collet
