Chicago-Latrobe 55435 Drill Bit

The Chicago-Latrobe 55435 is a Silver & Deming drill bit designed for general-purpose drilling in metal. It suits mechanics and fabricators who need a larger hole size with a standard shank fit.

35/64 inch diameter with 1/2 reduced shank

The decisive specification is the 35/64 inch cutting diameter paired with a 1/2 inch reduced shank. This allows the bit to be used in drill chucks that cannot accept a full-size shank while still delivering the larger hole required for the job.

118 degree point angle and black oxide finish

The 118 degree point angle provides reliable centring and chip evacuation in steel and cast iron. The black oxide finish reduces friction and resists corrosion during normal workshop use.

Questions about this item

How does the 35/64 in drill bit size translate to actual hole diameter in the workpiece?

The 35/64 in size means the bit cuts a hole exactly 35/64 of an inch in diameter, a standard fractional increment for Silver & Deming drill bits.

What does the 118 degree point angle limit when drilling different materials?

The 118 degree point angle is a general-purpose geometry suited for mild steel and softer metals; it is not optimised for hard alloys or deep-hole chip evacuation.

What chuck capacity is required to hold the 1/2 reduced shank on this bit?

The 1/2 reduced shank fits any drill chuck that accepts a 1/2 inch diameter shank, allowing use in standard 1/2 inch capacity drill presses and hand drills.
