Chicago-Latrobe 69850 15pc 135° Jobber Drill Bit Set

Chicago-Latrobe 69850 Jobber Drill Set

This 15-piece drill bit set from Chicago-Latrobe is built for general-purpose metal drilling in professional and workshop environments. Each bit features a 135-degree point angle designed to reduce walking and start cleanly on hard surfaces. The jobber length provides standard reach for common drilling tasks across steel, iron and other ferrous materials. It suits machinists, maintenance technicians and fabricators who need a reliable, ready-to-use assortment.

Sustained Drilling Performance

The high-speed steel construction resists heat buildup during repeated drilling cycles, helping the cutting edges stay sharp longer than standard carbon steel bits. Black oxide finish adds lubricity and reduces chip welding when working in steel or stainless alloys. Under continuous load the 135-degree split point maintains centring without a centre punch, so hole accuracy holds across a full shift. The set covers a practical range of diameters for progressive drilling without frequent bit changes.

15-Piece Capacity Decides Fit

The kit contains exactly fifteen jobber-length bits, so the purchase hinges on whether that quantity matches the range of hole sizes you drill most often. If your work regularly requires diameters outside this assortment, or if you need specialised coatings such as cobalt or titanium nitride for exotic alloys, this set will not cover those needs. Buyers who want a broader selection or application-specific coatings should look elsewhere.
