Chicago-Latrobe 53443 Cobalt Drill Bit
The Chicago-Latrobe 53443 is a reduced-shank drill bit manufactured from cobalt steel with a straw bronze finish. It features a 118-degree point angle designed for general-purpose drilling applications. This accessory fits power and pneumatic tools requiring a 43/64 inch cutting diameter.
Suited for machinists drilling hard metals
The cobalt construction withstands high heat when drilling stainless steel, cast iron and other tough alloys. The reduced shank allows use in chucks that cannot accept a full-size shank. Buyers who need a different cutting diameter or a split-point geometry for self-centering should look at other options.
