15-Piece Jobber Drill Set
This 15-piece drill bit set from Cle-Line covers common drilling tasks in metal, wood and plastic. The jobber length provides standard reach for workshop and maintenance work. It suits mechanics, fabricators and DIY users who need a ready-to-use assortment.
Black Oxide High-Speed Steel
Bits are made from high-speed steel with a black oxide finish that resists corrosion and reduces friction during cutting. The 118-degree point angle centres quickly without a pilot hole and performs well in general-purpose drilling. Normal use generates typical hand-tool heat and noise levels.
118-Degree Point Angle
The 118-degree point is optimised for general-purpose materials rather than hard or abrasive alloys. Buyers who need split-point starts, cobalt alloy life or specialised angles for stainless steel should look elsewhere.

Questions about this item
How do I install the 15 drill bits into a drill chuck without damaging them?
Insert each bit straight into the chuck jaws, tighten firmly by hand then with the chuck key if supplied, and avoid over-tightening which can crush the black-oxide coating.
When will the 118-degree high-speed steel tips need resharpening or replacement?
Resharpen when cutting edges dull or chip; the black-oxide finish wears first, so replace bits once the underlying steel shows through or the point angle deforms.
What limit appears first during sustained drilling with the 118-degree point angle?
Heat buildup at the tip softens the high-speed steel fastest, especially in harder metals, causing loss of edge before the shank or flute wears out.
