Cobalt Jobber Drill Bit

The Chicago-Latrobe 44916 is a 135-degree split-point drill bit made from cobalt steel with a TiAlN coating. It is designed for heavy-duty drilling in hard metals such as stainless steel and high-strength alloys. The jobber length suits general-purpose workshop and maintenance tasks.

Check Chuck Capacity

Verify that your drill chuck accepts a 1/4-inch shank before ordering. The bit has a decimal equivalent of .2500 and a fractional inch size with zero coolant holes. Confirm the material you intend to drill matches the bit's cobalt construction and split-point geometry for proper engagement.

Sustained Cutting Behaviour

Under continuous load the cobalt substrate and TiAlN coating resist heat buildup better than standard high-speed steel. The 135-degree split point reduces walking and maintains centering during extended drilling cycles. The non-coolant-through design means chips must be cleared manually in deep holes.

Questions about this item

Does the 44916 cobalt jobber bit come alone or in a set, and is a holder included?

The listing describes a single 135-degree split-point drill bit; no case, index or extra accessories are mentioned.

How do I decide between this 1/4-inch .2500 decimal bit and other sizes in the same series?

Choose the .2500 fractional-inch size when the hole must be exactly one-quarter inch; other diameters in the range are labelled with their own decimal equivalents.

What does the 135-degree point angle actually do when the bit is in a drill press or hand drill?

The 135-degree split point centres itself on contact, reduces walking and lowers thrust force, which is especially useful in hard materials such as stainless steel.
