13-Piece Cobalt Jobber Drill Set

The Chicago-Latrobe 69891 set contains 13 jobber-length drill bits made from cobalt material with a TiN finish. A 135-degree point angle helps reduce walking and improves penetration in tough alloys. The bits are designed for heavy-duty drilling tasks in professional workshops.

Mechanics drilling stainless steel

Cobalt construction with TiN coating suits repetitive drilling in hardened metals where standard high-speed steel wears quickly. The 135-degree split point aids accurate starts on curved surfaces. Buyers who need a wider range of diameters or specialist sizes for wood and plastic should look at something else.

135-degree split point geometry

The 135-degree point angle is the critical specification that determines suitability for hard metal drilling. It lowers thrust requirements and minimises bit wander on tough materials. Verify that your application benefits from this geometry before purchasing.

Questions about this item

What drill bits come in the 13-piece 69891 set?

The set contains 13 jobber-length cobalt drill bits with a 135-degree point angle and a TiN finish for reduced friction and longer life.

Which version of the 69891 should I choose for general-purpose metal drilling?

The 69891 is a single 13-piece configuration; its cobalt construction and 135-degree split point handle stainless steel, cast iron and other hard metals without needing a centre punch.

How does the 135-degree point perform when the bits are in a drill press or hand drill?

The 135-degree split point is self-centring, so it starts on contact and reduces walking on curved or hard surfaces, while the TiN coating lowers heat build-up during extended drilling.
