Drill Bit 33/64 Inch 118 Degree Point
The Chicago-Latrobe 55433 is a Silver & Deming drill bit with a 33/64 inch diameter and a 118 degree point angle. It is manufactured from high speed steel with a black oxide finish for general purpose drilling applications. The bit features a 1/2 inch reduced shank to fit standard drill chucks.
For General Machining With Half Inch Chucks
This bit suits machinists and maintenance technicians drilling metal stock using a drill press or handheld drill with a 1/2 inch capacity chuck. It is not for buyers who need a full shank matching the cutting diameter or a split point design for self-centring without a pilot hole.
Fits Standard Chucks Directly
Installation requires tightening the reduced shank into a 1/2 inch or larger drill chuck; no adapters or sleeves are needed. The most common issue is shank slippage if the chuck jaws are worn or not fully tightened on the reduced diameter section.

Questions about this item
What size drill chuck is required for the 1/2 reduced shank on the 55433 bit?
The 55433 bit has a 1/2 reduced shank, so it fits any drill chuck that opens to at least 1/2 inch.
Will the 118 degree point angle on the 55433 bit work well in the mild steel I usually drill with older high-speed steel bits?
Yes, the 118 degree point on the 55433 is a general-purpose angle that performs comparably to standard high-speed steel bits in mild steel.
How can I confirm the 55433 bit is cutting correctly after I install it?
The 55433 should produce continuous, straw-coloured chips and a clean 33/64 inch hole without excessive heat or chatter.
