13-Piece Heavy-Duty Drill Bit Set

This 13-piece drill bit set from Chicago-Latrobe is designed for general-purpose metal drilling in workshop and maintenance environments. The jobber-length bits suit standard drill chucks and everyday fastening tasks. It is not intended for specialised materials such as hardened steel, masonry or precision micro-drilling where dedicated tooling is required.

135-Degree Split Point and Black Oxide Finish

The 135-degree point angle reduces walking on hard surfaces and allows faster penetration without a centre punch. Black oxide finish adds lubricity and corrosion resistance during high-speed drilling. The geometry is optimised for ferrous metals; it offers no advantage in wood, plastics or composites where brad-point or spur bits perform better.

13 Bits Cover Common Jobber Sizes

Thirteen pieces provide a practical range of diameters for routine maintenance, fabrication and repair work. The set handles typical sheet-metal, plate and bar-stock thicknesses found in automotive and light-industrial jobs. Very large holes, deep-hole drilling or high-volume production runs will exceed the capacity of a 13-piece jobber assortment.

Questions about this item

Which drill bit set should I choose for general-purpose metal drilling?

This Chicago-Latrobe 69847 set contains 13 high-speed steel jobber-length bits with a 135-degree point angle and black oxide finish, designed for heavy-duty drilling in metal and other tough materials.

How does the 135-degree point angle perform when I start a hole in steel?

The 135-degree point is engineered for heavy-duty work; it centres quickly on hard surfaces, reduces wandering, and cuts efficiently through steel without needing a centre punch in most cases.

What shank type do these bits use and will they fit my 13 mm drill chuck?

Jobber-length bits have straight round shanks sized to their diameter; the largest bit in this 13-piece set will fit any standard 13 mm (1/2 inch) three-jaw chuck.
