Application Fit
The Cle-Line C20738 is a silver and deming drill bit with a 19/32 inch diameter and a 1/2 inch reduced shank. It is built for machinists and maintenance technicians who need to drill holes larger than a standard chuck capacity allows. The high-speed steel construction suits general-purpose metal cutting in workshop and job-site environments.
Upgrade Path
This bit replaces smaller-diameter twist drills when a 19/32 inch hole is required without stepping up to a larger chuck or Morse taper tool. The reduced shank lets you run the size in a common 1/2 inch three-jaw chuck, avoiding the cost and setup time of a dedicated large-capacity drill press. The jump is worth it when hole count justifies a dedicated large-diameter bit over reaming or step-drilling.
Sustained Use
The 118 degree point angle and black oxide finish work together to manage heat and resist wear during extended drilling cycles in steel and cast iron. High-speed steel retains hardness at the temperatures reached in prolonged cuts, while the oxide surface holds coolant and reduces galling. Consistent feed pressure and proper lubrication keep the bit cutting cleanly through deep holes without premature edge breakdown.

Questions about this item
Will the 1/2 reduced shank fit my drill chuck?
The 1/2 reduced shank is designed to fit standard drill chucks that accept a 1/2 inch shank diameter.
How do I properly install the 19/32 in drill bit and avoid the common mistake?
Insert the reduced shank fully into the chuck and tighten securely on the shank flats, not the flutes, to prevent slippage during drilling.
When will the 118 degree point on this high speed steel bit need resharpening or replacement?
Resharpen the 118 degree point when cutting edges dull or chip; replace the bit if the shank wears or the flute length shortens from repeated sharpening.
