What this drill bit does
The Chicago-Latrobe 70223 is a fractional-inch jobber bit sized at 23/64 in with a 118-degree conventional point. It is made from high-speed steel with a TiN coating for general-purpose drilling in metal, wood and plastic. The decimal equivalent is .3594 in.
Sustained drilling behaviour
Under continuous load the high-speed steel body resists softening while the TiN surface reduces friction and edge wear. The conventional point centres reliably on flat surfaces without walking. No internal coolant channels are present, so chips must be cleared by periodic withdrawal.
Heat, noise and power in use
The coating lowers cutting temperatures compared with uncoated steel, extending tool life in repetitive work. Noise and power draw depend entirely on the drill motor and workpiece material; the bit itself adds no vibration beyond normal cutting forces.

Questions about this item
Does the high-speed steel TiN construction keep the 70223 bit cool during long drilling sessions?
The 118-degree conventional point on the high-speed steel TiN bit helps dissipate heat while drilling, reducing friction buildup during extended use.
What chuck size do I need to hold the 23/64 in shank on this 70223 jobber bit?
A standard three-jaw chuck that opens to at least 0.3594 in will securely grip the 23/64 in fractional shank.
Will the 118-degree point on this 70223 bit start cleanly in the softer metals my older drill press typically handles?
Yes, the 118-degree conventional point is designed for general-purpose drilling in softer materials, making it compatible with older drill presses.
