Chicago-Latrobe 43623 135 Degree Heavy-Duty Jobber Length Drill Bit 23/64 in

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.
