45/64 in Drill Bit with Reduced Shank

This Chicago-Latrobe 53445 drill bit measures 45/64 in and features a 118 degree point angle. The reduced shank design allows use in chucks with 1/2 in capacity. It is built from HAWA material with a straw/bronze finish for general-purpose drilling.

118 Degree Point Angle for General Drilling

The 118 degree point angle is the standard geometry for drilling into a wide range of materials including steel and cast iron. This angle provides reliable centering and chip evacuation without specialised tooling. The HAWA material construction supports durability under normal machining conditions.

Suited for Machinists Using 1/2 in Chucks

This bit suits machinists and maintenance technicians who need a 45/64 in hole and have a drill press or hand drill limited to a 1/2 in chuck capacity. Buyers who need a full-size shank for maximum rigidity or who require a split-point design for harder alloys should look at something else.

Questions about this item

What does the 118 degree point angle mean when I use this drill bit?

The 118 degree point angle is a standard geometry for general purpose drilling in metal, wood and plastic. It centres easily on a punch mark and clears chips well in a hand held drill or drill press.

How does the 1/2 inch reduced shank work with my drill chuck?

The shank is turned down to 1/2 inch so the 45/64 inch cutting diameter fits a standard 1/2 inch three jaw chuck. Tighten the chuck fully on the reduced section for secure grip.

What clearance do I need for the 45/64 inch cutting diameter?

The bit cuts a 45/64 inch hole. Ensure the workpiece and any drill press table slot are wide enough for that diameter and that the chuck capacity covers the 1/2 inch shank.
