Cle-Line C17040 Reduced Shank Drill Bit
This 21/32 inch drill bit is designed for general-purpose drilling in metal and wood. It suits trade professionals and serious DIY users who need a reliable high-speed steel cutter. The reduced shank allows use with standard 1/2 inch chucks.
Thermals Noise and Power Draw
The high-speed steel construction manages heat effectively during normal drilling operations. Friction generates typical warmth for this material class without excessive buildup. Noise levels depend on the drill motor and workpiece rather than the bit itself.
Behaviour Under Sustained Load
The 118 degree point angle maintains cutting efficiency during extended drilling sessions. Black and gold finish resists wear when working through tougher materials. The bit retains its geometry under continuous use without premature dulling.

Questions about this item
How do I fit the 1/2 reduced shank into my drill chuck, and what step do people miss?
Open the chuck wide enough for the 1/2 shank, insert the bit fully, then tighten securely; the step often missed is not seating the shank all the way before locking the chuck.
What wear or replacement should I expect with the high speed steel 118 degree point?
The cutting edges will dull over time; resharpen the 118 degree point or replace the bit when drilling 21/32 holes becomes slow or produces rough edges.
At what point does the black and gold finish limit performance during sustained drilling?
The finish helps with chip flow and heat, but under continuous heavy feed the high speed steel tip will overheat first, causing loss of hardness and faster wear.
