Reduced Shank Drills
Reduced-shank drill bits have a shank turned down smaller than the drill body, so you can chuck a large-diameter bit in a standard 3/8″ or 1/2″ drill. That means bigger holes without needing an oversized or industrial drill.
Ideal for metalworkers, fabricators and tradespeople who need above-1/2″ holes from an ordinary drill. See also our Silver & Deming drills for the same large-hole capability.
