AT REDUCED SHANK DRILLS

Alfa Tools manufactures reduced shank drills (also called Silver & Deming drills or S&D drills), specialized twist drills with smaller-diameter shanks than their cutting diameter, enabling large-hole drilling (9/16" to 1-1/2"+) using standard drill chucks (3/8" or 1/2"). Without reduced shank drills, drilling holes larger than 1/2" requires expensive large-capacity drill chucks (5/8", 3/4", 1") or magnetic drill presses—reduced shank drills eliminate this limitation by fitting standard equipment while delivering full-size hole capacity. Featuring 1/2" shanks (most common), 3/8" shanks (for smaller drills), and 3/4" shanks (for industrial applications), Alfa Tools reduced shank drills are essential for structural steel fabrication, heavy equipment repair, electrical installations, plumbing, HVAC, and any application requiring large holes without specialized equipment.
