Heavy-Duty Drill Bit for Deep Holes
This Chicago-Latrobe 50648 bit is built for tradespeople who need to reach deep into thick workpieces. The extra-long design allows a maximum drilling depth of 9 in, making it suited for through-holes in heavy timber or stacked metal. The high-speed steel body with black oxide finish resists wear during extended use. It targets professional maintenance and fabrication tasks where standard-length bits fall short.
118-Degree Notched Point for General Machining
The 118 degree point angle combined with a notched tip is the single specification that determines whether this bit matches the material and machine rigidity. This geometry is rated for general-purpose machining across ferrous and non-ferrous metals. The 28 degree helix angle supports chip evacuation in deep holes. Select this bit only when the application calls for a conventional 118 degree profile rather than a split-point or parabolic design.
Black Oxide Finish Reduces Friction
The black oxide surface treatment lowers friction and helps retain cutting fluid during long cuts. This coating extends edge life in repetitive drilling cycles without adding a separate lubrication step. No additional accessories or software are included with the bit. The performance gain comes solely from the factory-applied finish on the high-speed steel substrate.

Questions about this item
How deep can the 23/32 inch drill bit reach in a single pass?
The extra-long design allows a maximum drilling depth of 9 inches, suitable for deep-hole applications in general-purpose machining.
What does the 118-degree point angle mean for everyday drilling?
The 118-degree notched point is a standard general-purpose geometry that centres easily in steel and wood without specialised equipment.
What shank size does the 50648 bit need to fit my drill chuck?
The fractional 23/32 inch diameter typically requires a chuck capacity of at least 3/4 inch to secure the shank properly.
