A 118-degree high-speed steel drill bit with a reduced shank for drilling 5/8-inch holes, finished in black oxide
This Chicago-Latrobe 52440 drill bit features a 118-degree point angle and a 1/2 reduced shank for use with standard drill chucks. It is manufactured from high speed steel with a black oxide finish for durability. The tool suits general-purpose drilling in metal and wood applications.
This bit suits machinists and technicians needing a reduced-shank drill for larger diameters in a standard chuck. Buyers who require a different point angle for specialised materials should look at other options. It is not intended for applications demanding carbide-tipped construction or coolant-fed designs.
The 118-degree point angle provides a standard cutting profile suitable for a wide range of materials. The 1/2 reduced shank allows the 5/8 inch drill bit to fit chucks with smaller capacity. Verify that your equipment accepts this shank configuration before purchase.

The box contains the single 5/8 inch Silver & Deming drill bit with a 1/2 inch reduced shank that fits directly into a standard 1/2 inch drill chuck, so no extra chuck or adapter is required.
The 52440 is offered as one specific drill bit — 5/8 inch diameter, 118 degree point angle, high-speed steel with black oxide finish — so there are no alternative capacities or versions to select from.
The 118 degree point is a general-purpose geometry that centres easily in steel and other common metals, giving reliable starts and steady cutting without the need for a pilot hole in most workshop tasks.
