Cle-Line 13-Piece Jobber Drill Set
This Cle-Line drill set contains 13 high-speed steel jobber bits with a 135-degree point angle and a black oxide finish. It is designed for general-purpose drilling in metal, wood and plastic where a durable, heavy-duty bit is required.
For trade users and DIYers needing a compact
Buyers who need a wider range of diameters or specialised bits for masonry, glass or tile should look at other sets. The 13-piece count limits the selection to the most common sizes for everyday tasks.
135-degree point angle on high-speed steel
The 135-degree point is the key specification that determines suitability for harder materials and reduced bit walking. Match this angle to your drilling requirements before purchase.

Questions about this item
How do I install the 135-degree split-point bits into a drill chuck without slipping?
Insert each bit fully into the chuck jaws, tighten firmly on the shank flats, and start drilling at low speed so the 135-degree point self-centres before applying full pressure.
What maintenance will the black-oxide high-speed steel bits need after repeated use?
Wipe chips off after each job, apply a light oil coat to prevent rust on the black-oxide finish, and resharpen the 135-degree point when cutting edges dull.
At what point does heat buildup limit continuous drilling with these jobber-length bits?
Sustained high-speed drilling in hard steel will overheat the high-speed steel first, causing the black-oxide finish to discolour and the 135-degree cutting edges to lose hardness.
