21-Piece 135° Jobber Drill Set
This 21-piece drill bit set from Cle-Line uses high-speed steel with a titanium nitride finish. The 135-degree split-point angle reduces walking and starts holes cleanly. It is suited for general-purpose metal drilling in a workshop or job-site environment.
Jobber Length Fit and Storage
Jobber-length bits reach standard depths without the bulk of longer series drills. The transparent case keeps each size visible and protected while taking minimal drawer space. No special chuck or adaptor is required beyond a standard three-jaw drill chuck.
Upgrade from Basic Carbon-Steel Sets
The high-speed steel construction and TiN coating resist heat and wear better than uncoated carbon-steel bits. The jump is worth it when drilling harder alloys or when bit life and hole accuracy matter more than lowest upfront cost. Not for buyers who need cobalt or carbide grades for abrasive materials.

Questions about this item
How long do the 135-degree points stay sharp under heavy drilling?
The TiN coating on the high-speed steel bits reduces wear so the 135-degree split points keep cutting longer than uncoated drills.
Do the bits get too hot to handle during a full day of use?
The parabolic flute design clears chips faster, which lowers heat build-up even when the 21-piece set runs continuously.
What chuck size do I need to run the full 21-piece set?
Standard 3/8-inch and 1/2-inch drill chucks accept every bit in the jobber-length range included.
