Chicago-Latrobe 52449 Silver & Deming Drill
The Chicago-Latrobe 52449 is a Silver & Deming drill bit sized at 49/64 in. It features a 118 degree point angle and a reduced 1/2 in shank for compatibility with standard drill chucks. This tool targets machinists and maintenance technicians who need to enlarge existing holes in metal workpieces.
High-Speed Steel Construction Under Load
The bit is manufactured from high-speed steel with a black oxide finish to resist wear during sustained cutting. The 118 degree point geometry centres the bit quickly and reduces walking when pressure is applied continuously. This construction helps maintain cutting edges during prolonged drilling sessions in steel and other ferrous materials.
Replaces Worn General-Purpose Bits
This drill upgrades from standard twist bits that lack the reduced shank required for larger diameters in a 1/2 in chuck. The jump is worth it when a machinist needs a single bit to finish a 49/64 in hole without switching to a Morse taper or specialty holder. It is not for buyers who need a full set of incremental sizes or bits designed for non-ferrous materials only.

Questions about this item
Does the 118-degree point angle on the 49/64 in drill bit cause extra heat or vibration during all-day drilling?
The 118-degree point is a standard general-purpose angle that centres quickly and reduces wandering, keeping heat and vibration low during extended use in steel or iron.
What shank size must my drill chuck accept to run the 49/64 in bit with its reduced shank?
The bit has a 1/2 in reduced shank, so your drill needs a chuck that opens to at least 1/2 in.
Will the black oxide finish on this 49/64 in bit wear faster when I use it in my older 1/2 in chuck drill?
Black oxide holds lubricant and resists corrosion, so it lasts well even with the run-out common on older 1/2 in chuck drills.
