Chicago-Latrobe 44957 Cobalt Steel Jobber Bit

This Chicago-Latrobe 44957 jobber bit is a cobalt steel drill bit designed for power and pneumatic tool use. It features a split point tip with a 135 degree angle and a TiAlN coating. The bit carries a decimal equivalent of .2950 and corresponds to letter size M.

Suited for drilling hard metals

The cobalt construction and split point geometry suit users drilling tough alloys or stainless steel where standard high-speed steel wears quickly. The TiAlN coating supports higher cutting speeds in those materials. Buyers needing coolant-through capability or a different letter size should look at alternative bits.

Questions about this item

How can I confirm the 135-degree split point is cutting correctly after setup?

The bit should self-centre without walking, produce short curled chips in steel, and the hole diameter should measure .2950 inch.

What comes in the box and is anything else required to use the 44957 bit?

The package contains the cobalt steel jobber bit with TiAlN coating; a compatible drill chuck or collet is needed separately.
