Drill bit for 43/64 inch holes
This Chicago-Latrobe drill bit creates 43/64 inch diameter holes using a 118 degree point angle. The high speed steel construction handles general machining tasks. A reduced shank of 1/2 inch allows use in smaller chucks. The black oxide finish adds surface protection during cutting operations.
Suited for general machining with standard chucks
Machinists needing a 43/64 inch hole in metal stock will find this bit fits the requirement. The 1/2 inch shank works with common drill presses and hand drills. Builders needing larger shank diameters or specialised coating types should look at other tooling options. The bit addresses a specific fractional size without extra features.
Consistent cutting under sustained load
High speed steel maintains hardness when heat builds during extended drilling sessions. The 118 degree point centres the bit reliably across repeated holes. Black oxide reduces friction as temperatures rise in continuous use. The reduced shank transmits torque without slipping in the chuck during long cycles.

Questions about this item
Will my drill chuck accept the 1/2 reduced shank on this 43/64 bit?
The 1/2 reduced shank fits any chuck that opens to at least 1/2 inch, so a standard 1/2-inch capacity drill will hold it securely.
Can I use this 118-degree high-speed steel bit in the same job as my older cobalt bits?
Yes, the 118-degree point angle and high-speed steel construction let it work alongside cobalt bits in general-purpose drilling without changing technique.
How do I confirm the black oxide finish is performing as intended after I start drilling?
The black oxide surface should show even wear and resist blueing while cutting; consistent chip ejection and steady feed indicate it is working correctly.
