45/64-inch drill bit
The Cle-Line C20745 is a Silver & Deming drill bit sized at 45/64 inch with a 1/2 reduced shank. It is built from machining high speed steel and finished in black oxide. The 118 degree point angle suits general-purpose drilling in metal and wood. It fits standard 1/2 inch chucks for broad compatibility.
Thermals noise and power
As a manual cutting tool, the bit produces no electrical noise and draws no power of its own. Heat generated during cutting depends on the workpiece material, drill speed and lubrication used. Proper cutting fluid and speed selection keep temperatures manageable. The black oxide finish helps reduce friction during operation.
Sustained load behaviour
Under continuous drilling the high speed steel construction maintains edge retention through repeated cuts. The reduced shank design transmits torque without slipping in the chuck. Chip evacuation relies on flute geometry and operator technique rather than forced cooling. Performance stays consistent when feed pressure and speed match the material.

Questions about this item
How do I install the 1/2 reduced shank on this 45/64 drill bit without it slipping?
Tighten the drill chuck fully onto the 1/2 reduced shank until the jaws grip the narrower section securely. The step people miss is confirming the shank seats past the jaws, not just the flutes, otherwise the 118 degree point can walk on hard steel.
When will the black oxide finish on this HAWA high-speed steel bit need replacement?
The black oxide coating wears away as the 118 degree point cuts through material. Replace the bit once the finish is gone from the cutting lips or the 45/64 diameter no longer drills true, since the coating cannot be restored.
What limit appears first when drilling continuously with this 118 degree point angle?
Heat builds at the 118 degree point during sustained drilling, dulling the HAWA high-speed steel cutting edges before the 1/2 reduced shank or black oxide finish fails.
