Chicago-Latrobe 54110 Cobalt Jobber Drill

The Chicago-Latrobe 54110 is a heavy-duty cobalt jobber length drill bit designed for demanding drilling tasks in metal. Its split point geometry promotes accurate starts and reduces walking on hard surfaces.

135 Degree Split Point Limitation

The 135 degree point angle excels in harder materials such as stainless steel but can grab aggressively in softer alloys or plastics. The non-coolant through design requires external lubrication for deep holes.

.2810 Diameter Capacity

At a .2810 inch decimal equivalent this bit handles medium diameter holes in tough metals with good chip clearance. It reaches its practical limit in very deep holes where coolant through capability would be needed.

Questions about this item

What does the 135-degree split point do for drilling accuracy?

The 135-degree split point is self-centering and reduces walking on hard surfaces, improving hole placement accuracy without a center punch.

How does the cobalt material with TiN coating perform in a real drill?

Cobalt steel with TiN coating resists heat and wear better than standard high-speed steel, extending bit life when drilling stainless steel and other tough alloys.

What shank type does the 54110 use and will it fit my drill chuck?

The 54110 has a straight round shank sized to its .2810 inch diameter, so it fits any standard three-jaw drill chuck that accepts that size.
