118 Degree Silver & Deming Drill 11/16 in
The Chicago-Latrobe 55444 is a Silver & Deming drill bit designed for drilling larger diameter holes with a standard drill chuck. It suits machinists and maintenance technicians who need a 11/16 inch cutting diameter on a 1/2 inch reduced shank. The 118 degree point angle provides a conventional geometry for general purpose drilling tasks.
High Speed Steel Build with Black Oxide Finish
The bit is manufactured from high speed steel and features a black oxide finish for corrosion resistance and reduced friction during operation. The reduced shank allows the large cutting diameter to be used in power tools equipped with a 1/2 inch chuck capacity. This configuration makes the tool compatible with common bench drills and heavy duty handheld units without requiring a larger chuck.
Replaces Worn Large Diameter General Purpose Bits
This drill bit replaces worn or damaged large diameter twist drills used in steel, cast iron, and other ferrous materials. The upgrade is worth it when an existing bit no longer cuts cleanly or has lost its point geometry. It is not suited for buyers who need a split point for self-centering, a cobalt alloy for high heat applications, or a different shank configuration for specific tool holders.

Questions about this item
What does the 118 degree point angle mean for drilling?
The 118 degree point angle is a general-purpose geometry that centers well in metal, wood and plastic without needing a pilot hole.
Will the 1/2 reduced shank fit my drill chuck?
The reduced 1/2 inch shank fits any three-jaw chuck that opens to 1/2 inch or larger, so it works in most standard drills and drill presses.
How do I install the bit so it does not slip?
Open the chuck fully, insert the shank until it seats against the jaws, then tighten each jaw evenly with the key or sleeve — skipping the final snug turn is the step most people miss.
