Questions about this item
How do I install the 1/2in shank on my drill, and what step is often missed?
Insert the 1/2in shank fully into the chuck and tighten each flat against a jaw so the 3-flat design prevents spin under load.
What maintenance or replacement will the 43/64in HSS bit need later?
Resharpen the heavy-duty split point when cutting slows, and replace the bit if the flutes wear past the 3in flute length or the shank flats deform.
