The Faithfull Heavy Duty Keyed Chuck and SDS Plus Adaptor is a versatile drilling accessory designed for use with rotary drills, impact drills, and SDS Plus machines. This professional-grade keyed chuck features an anti-thrust bearing that increases grip strength and prevents slipping when drilling under load, making it ideal for demanding applications where consistent performance is essential. Manufactured to DIN 6349 standards, this heavy-duty chuck offers a 13mm capacity and is fitted with a 1/2in x 20 UNF thread for secure attachment. The inclusion of an SDS Plus adaptor extends compatibility to SDS and SDS Plus machines, though it's important to note that hammer mode must not be engaged when using this chuck with SDS drills.
