PLEASE NOTE INSERT REQUIRED The SuperNOVA2 Companion version comprises a main body, jaw slides and chuck key. A wide range of adaptors enables the SuperNOVA2 Companion to fit onto a large variety of lathes. When ordering please specify which adaptor you need to suit your lathe, this will be at extra cost. This 100mm diameter, high tensile steel, nickel plated, self-centring chuck is the ideal chuck for the ambitious woodturner. The SuperNOVA2 chuck is suitable for lathes with up to 500mm diameter swing. It has an excellent safety feature in the Auto-Stop, which prevents the jaws protruding from the body of the chuck. The rear of the chuck features a Duracon composite backing plate with 24 division indexing. The plate also keeps dust and debris away from the chuckâ€™s mechanism.
