Chicago-Latrobe 52443 118 Degree Silver & Deming Drill 43/64 in 1/2 Reduced Shank

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.
