13-Piece Jobber Drill Bit Set
This 13-piece drill bit set from Cle-Line is built for everyday drilling in metal, wood and plastic. The 135-degree split point reduces walking and starts holes cleanly without a centre punch. It suits maintenance technicians, fabricators and serious DIYers who need a reliable, general-purpose kit.
High-Speed Steel with Black Oxide Finish
Each bit is ground from high-speed steel and coated with a black oxide finish that resists corrosion and reduces chip welding. The jobber length provides standard reach and rigidity for handheld drills and drill presses alike. The 135-degree point geometry allows faster penetration and less thrust in harder materials.
Replaces Worn or Mixed Assortments
This set replaces dull, mismatched or incomplete bit collections with a single indexed case covering common fractional sizes. The upgrade is worth it when your current bits wander, overheat or leave rough holes in steel. Buyers who need specialised cobalt, carbide or extra-long bits should look elsewhere.

Questions about this item
What drill-point angle do the 13 bits in the C21157 set use?
Every bit in the 13-piece set is ground to a 135-degree split point, which reduces walking and starts holes cleanly in metal.
What shank style do these jobber-length bits have so I know they fit my drill?
The bits are straight-shank jobber length, so they clamp directly into any standard three-jaw drill chuck without an adapter.
How do I install a bit from this set without damaging the black-oxide finish?
Insert the bit fully into the chuck jaws, tighten evenly by hand then with the chuck key, and avoid over-tightening which can mar the oxide coating.
