Questions about this item
How do I install the 1/4 inch HSS drill bit with 135 degree split point into my drill chuck, and what step do people often miss?
Open the chuck fully, insert the shank until it seats, then tighten securely; the step often missed is checking that the split point runs true before drilling.
What maintenance or replacement will the Chicago-Latrobe 11108 extra long drill bit need after extended use?
The black oxide coating reduces friction, but the 135 degree split point will dull over time; resharpen or replace when cutting performance drops.
