Chicago-Latrobe 55468 Silver & Deming Drill
This Chicago-Latrobe 55468 is a Silver & Deming drill bit designed for drilling large-diameter holes with a standard drill chuck. It features a 1/2 reduced shank that allows compatibility with 1/2-inch chucks despite the larger cutting diameter. The tool is manufactured from high-speed steel with a black oxide finish for durability and corrosion resistance. It is supplied new and intended for general-purpose machining applications.
Suited for machinists needing large holes in metal
This drill suits machinists and fabricators who need to bore 1 1/16 inch holes in metal using a drill press or heavy-duty handheld drill limited to a 1/2-inch chuck capacity. The 118-degree point angle provides effective centring and cutting in steel and similar materials. Buyers who require a different drill bit size, a standard straight shank without reduction, or a specialised point geometry for very hard alloys should look at alternative tooling. The black oxide finish aids chip flow in ferrous metals.
1 1/16 inch cutting diameter with 1/2 reduced shank
The defining specification is the 1 1/16 inch cutting diameter paired with a 1/2 reduced shank, which determines whether this bit fits the user's chuck and produces the required hole size. The high-speed steel construction and 118-degree point angle support general machining in steel and iron. Verify that the target hole diameter and chuck capacity match these dimensions before purchase. The model number 55468 identifies this specific configuration.

Questions about this item
How can I verify the 118-degree point angle is cutting correctly after installing the 55468 drill bit?
A properly cutting 118-degree point produces even chips and a round hole without wandering; if the bit chatters or leaves a triangular hole, re-sharpen or replace it.
What comes in the package with the Chicago-Latrobe 55468 and what must I supply separately?
The box contains the single 1 1/16-inch high-speed steel drill bit with black-oxide finish; you must provide a compatible 1/2-inch chuck drill motor and cutting fluid.
Which capacity of the Silver & Deming series should I choose for a 1 1/16-inch hole?
Select the 55468 model, which is the 1 1/16-inch size in this reduced-shank series.
