Cle-Line C17039 Reduced Shank Drill Bit
The Cle-Line C17039 is a Silver & Deming drill bit with a 41/64 in diameter and a 1/2 in reduced shank. It features a 118 degree point angle and is made from high speed steel with a black and gold finish. This bit is built for general purpose drilling in metal, wood and plastic.
Who this suits and who should look elsewhere
Machinists and maintenance technicians who need a large diameter hole but only have a 1/2 in chuck will find this bit fits directly. Buyers who need a bit for a chuck smaller than 1/2 in cannot use this reduced shank design. Users who require a different drill point geometry or a specialty coating for exotic alloys should look elsewhere.
The specification that decides fit
The 1/2 in reduced shank is the single dimension that determines whether this bit works with your drill. If your chuck capacity is 1/2 in or larger, the bit will seat securely. If your chuck capacity is smaller, this bit will not fit and a different shank style is required.

Questions about this item
What does the 118-degree point angle on the C17039 drill bit cap in practice?
The 118-degree point angle is designed for general-purpose drilling in materials like mild steel and cast iron, providing a balance of centering accuracy and chip clearance for standard workshop tasks.
What physical dimensions does the 1/2 reduced shank on the 41/64 in bit need to fit?
The 1/2 reduced shank fits standard drill chucks with a 1/2-inch capacity, allowing the larger 41/64-inch cutting diameter to be used in smaller drill presses or hand drills.
How is the Silver & Deming drill bit installed, and what step do people often get wrong?
Insert the reduced shank fully into the chuck jaws and tighten securely on the flat shank surfaces; the common error is clamping on the fluted body instead of the shank, causing slippage and damage.
