This longer extension is perfectly suited to deep-drilling tasks through thick timbers, multiple joists, or hard-to-access cavities where a shorter extension simply won’t reach. The 1/4-inch impact-rated hex shank ensures a secure and robust connection to both impact drivers and drill drivers, maintaining control and accuracy even at extended lengths. Designed for use with Bosch Self-Cut Speed spade bits, this extension is a must-have for contractors and tradespeople tackling challenging first-fix or installation work.
