29-Piece Cobalt Drill Set

The Chicago-Latrobe 57850 contains 29 jobber-length drill bits made from machining cobalt. It is designed for professionals and serious DIY users who need reliable performance across a range of metalworking tasks. The straw/bronze finish helps identify the bits quickly in a busy workshop.

135-Degree Split Point Geometry

Every bit in the set features a 135-degree point angle engineered for heavy-duty drilling. This geometry reduces walking on hard surfaces and improves penetration in tough alloys. It is the single specification that determines whether the set matches the material hardness you work with daily.

Jobber Length for Standard Chucks

The bits use a standard jobber length that fits common drill chucks without adapters or extensions. This compatibility frees up time otherwise spent swapping tooling or hunting for collets. The set covers a broad range of diameters so you can move between pilot holes and clearance drilling without changing cases.

Questions about this item

What does the 135-degree point angle mean when I use these bits in a drill?

The 135-degree point angle helps the bit start on contact and reduces walking, especially on hard metals where cobalt performs best.

How does the jobber length affect what I can drill?

Jobber length gives a standard flute and overall length that fits most drill chucks and covers common hole depths in metalwork.

Will the 29-piece set fit in a standard tool chest drawer?

The set comes in a fitted case sized to hold all 29 bits securely, designed to store neatly in a typical toolbox drawer.
