Chicago-Latrobe 43623 Jobber Drill Bit
The Chicago-Latrobe 43623 is a fractional-inch drill bit sized at 23/64 in with a decimal equivalent of .3594. It is built from high-speed steel with a TiCN coating for extended wear resistance. The 135-degree split point reduces walking and starts holes accurately. This accessory targets machinists and maintenance technicians drilling steel and cast iron.
Sustained drilling performance
The TiCN coating maintains hardness at higher temperatures generated during continuous cutting. High-speed steel substrate resists softening when feed rates are held steady over long cycles. The split-point geometry keeps centring stable without a pilot hole as the bit advances. Non-coolant-through design means chips evacuate through flutes rather than internal passages.
23/64 in fractional size
The single specification that decides fit is the 23/64 in diameter, which equals .3594 in decimal. Buyers needing a different fractional or metric diameter cannot use this bit. The jobber-length flute and overall length suit standard drill chucks and drill-press spindles. No other size in this listing will satisfy a 23/64 in hole requirement.

Questions about this item
How much heat does the 135 degree split point generate when drilling steel all day?
The 135 degree split point reduces thrust and friction, so the high speed steel bit runs cooler during extended drilling in metal.
What shank size must my drill chuck accept for the 23/64 inch bit?
The jobber length bit has a straight shank matching its 23/64 inch diameter, requiring a chuck capacity of at least 0.3594 inch.
Will the TiCN coating stay sharp when I use the bit in my older variable-speed drill press?
Yes, the TiCN coating resists wear at the lower RPMs typical of older drill presses, keeping the 135 degree point sharp longer.
