Chicago-Latrobe 44968 Cobalt Jobber Bit

This Chicago-Latrobe 44968 drill bit is a heavy-duty cobalt jobber length tool built for demanding metalworking tasks. It suits machinists and maintenance technicians who need reliable performance in tough alloys and stainless steel.

Split Point and TiAlN Coating Benefits

The 135 degree split point design reduces walking and starts holes accurately without a centre punch. A TiAlN coating increases surface hardness and heat resistance, extending tool life when drilling abrasive or high-temperature materials.

Straightforward Chuck Installation

The bit installs directly into any standard drill chuck that accepts its shank diameter. No coolant holes are present, so internal cooling cannot be used; external lubrication is required for deep cuts. Users who need through-coolant capability or a different point angle will need another tool.

Questions about this item

Will the cobalt tip need re-sharpening after extended use?

The 135-degree split point is designed to stay sharp longer than standard bits, but heavy drilling in hard materials will eventually require professional re-grinding.

At what point does the TiAlN coating wear through during continuous drilling?

The TiAlN coating reduces heat buildup, yet sustained high-speed work in abrasive alloys will erode the surface once the coating thickness is exhausted.

How hot does the shank get during all-day production runs?

Cobalt steel transfers heat efficiently; the shank will become hot to the touch during non-stop drilling, so allow cooling intervals or use cutting fluid.
