Chicago-Latrobe 53449 Reduced Shank Drill
The Chicago-Latrobe 53449 is a Silver & Deming drill bit with a 49/64 inch cutting diameter and a 1/2 inch reduced shank. It is designed for machinists and maintenance technicians who need to drill large holes using a standard 1/2 inch capacity drill chuck. The 118 degree point angle and cobalt construction suit general-purpose metal drilling tasks.
Installation fits standard chucks
The reduced shank allows the bit to be secured in any 1/2 inch three-jaw chuck without a specialty holder. Cobalt steel provides heat resistance but is more brittle than high-speed steel. Excessive feed pressure or misalignment can cause the cutting edges to chip or the bit to snap at the shank transition. Steady pressure and cutting fluid prevent premature failure.
Suited for machinists drilling large holes in metal
This bit serves workshops enlarging existing holes or drilling 49/64 inch diameter through-holes in steel, cast iron or similar alloys using a benchtop or handheld drill. It is not for buyers who need a full 1/2 inch shank for maximum rigidity in heavy CNC operations. Builders requiring a split-point geometry for self-centering on curved surfaces or a different point angle for specialised alloys should look at alternative geometries.

Questions about this item
How can I verify the 118 degree point angle is cutting correctly after installing the 49/64 in drill bit?
The 118 degree point angle should centre itself without wandering; a clean, round hole in steel with consistent chip formation shows the Chicago-Latrobe 53449 is working as intended.
What comes in the package with the 49/64 in Silver & Deming drill and what must I supply?
The box contains the single 49/64 in cobalt drill bit with a 1/2 reduced shank; you must provide a compatible drill motor and cutting fluid.
Which Chicago-Latrobe 53449 variant should I select for a 49/64 in hole in metal?
The 53449 is offered in the 49/64 in size with 118 degree point and cobalt construction; choose this version when that exact diameter and material are required.
