Chicago-Latrobe 43782 Jobber Drill Bit
This Chicago-Latrobe 43782 jobber drill bit is made from high speed steel with a TiCN coating for extended tool life. It features a 135 degree split point that starts on contact and reduces walking on hard materials. The bit suits mechanics and fabricators drilling precise holes in metal stock.
.2900 diameter with split-point geometry
The split point geometry eliminates the need for centre punching in most applications and improves chip evacuation during deep cuts. TiCN coating increases surface hardness and heat resistance compared to uncoated bits. Buyers needing coolant-through capability or larger diameters should select a different tool.

Questions about this item
How often will the TiCN coating on this 43782 bit need to be refreshed?
The TiCN coating is a permanent surface treatment; it cannot be reapplied once it wears away, so the bit is replaced instead of recoated.
What limits continuous drilling with the .2900 split-point geometry?
Heat buildup at the 135-degree point is the first limit; sustained use without cooling dulls the split-point edges and reduces cutting efficiency.
