Chicago-Latrobe 42623 drill bit
The Chicago-Latrobe 42623 is a jobber length drill bit made from high speed steel with a TiAlN coating. It features a 135 degree split point design for accurate starting and reduced walking. The fractional size is 23/64 inch with a decimal equivalent of .3594. This accessory is designed for general purpose drilling applications.
Suited for metal drilling tasks
This bit suits users drilling into metal where the split point geometry helps centre the hole without a centre punch. The TiAlN coating adds wear resistance for extended tool life in steel and alloy materials. Builders needing coolant-through capability or larger diameter holes should look at other tooling options. The non-coolant design limits deep hole chip evacuation.
23/64 inch capacity and limits
The .3594 inch diameter handles medium sized fastener clearance and tapping operations comfortably. The jobber length flute provides standard reach for through holes in plate and bar stock. Without coolant holes the bit runs out of effective chip removal in deep holes or high volume production runs. High speed steel construction withstands normal drilling heat but wears faster than carbide in abrasive alloys.

Questions about this item
What chuck capacity do I need on my drill to hold the 23/64 inch shank?
A chuck that opens to at least .3594 inch or 23/64 inch will grip the bit securely.
Can I use this 135 degree split point bit in the same drill press I ran older bits in?
Yes, it fits any standard drill press or hand drill that accepts a straight shank of this diameter.
How will I know the split point is centring correctly on first contact?
The bit should bite immediately without walking, producing a clean, centred hole from the start.
