Drillco 1-5/64" S&D Drill, 1/2" Shank (1000A205)
Drillco 1000A205 1-5/64" S&D Drill, 1/2" Shank is a precision-engineered cutting tool from the Drillco 1000 Series Silver & Deming line, designed to expand the drilling range of standard 1/2" portable drill chucks. With a 1/2" reduced shank, it allows users to drill large-diameter holes using handheld drills, eliminating the need for special equipment. This drill bit features advanced design elements including a unique spiral flute for improved chip removal, a heavy-duty core for durability, and a 135° split point for accurate starts without walking. TiN coating enhances lubricity and extends tool life, making it suitable for demanding, high-wear applications. Made in the USA, this jobber-length bit is ideal for both general and industrial use on low to medium tensile strength metals.
