Chicago-Latrobe 48516 Drill Bit
This Chicago-Latrobe 48516 drill bit is a screw machine length tool designed for general-purpose drilling in metal and other materials. It suits machinists, maintenance technicians and hobbyists who need a reliable high-speed steel bit for standard drilling tasks. The bright uncoated finish provides a cost-effective option for everyday workshop use.
1/4 inch capacity and 118 degree point
The bit features a 1/4 inch diameter with a decimal equivalent of .2500 and a conventional 118 degree point angle. This geometry handles a wide range of common materials including mild steel, aluminium and plastic with good centring and chip evacuation. The screw machine length offers rigidity for portable drilling but lacks the reach of jobber or taper length bits for deep holes. The right-hand cutting direction matches standard drill chucks and the non-coolant-through design limits use in high-volume production with through-spindle cooling.
Upgrading from worn or smaller bits
This bit replaces dull, damaged or undersized drill bits in a 1/4 inch size. The jump is worth it when a sharp high-speed steel edge restores clean hole quality and cutting speed in maintenance or light fabrication work. It is not for buyers needing coated bits for extended life in abrasive alloys, coolant-through capability for deep hole drilling, or left-hand cutting direction for extractor applications.

Questions about this item
Will the 1/4 in 118-degree point work with my older 3/8 in chuck drill?
Yes, the 1/4 in shank fits any standard 3/8 in or 1/2 in drill chuck, and the 118-degree point is designed for general-purpose drilling in metal, wood and plastic with existing corded or cordless drills.
How do I verify the 48516 bit is cutting correctly after I install it?
The bit should produce clean, round holes at the 0.2500 decimal equivalent diameter with minimal wandering; steady chip evacuation and no excessive heat indicate the 118-degree conventional point is performing as intended.
Does the box include any lubricant or only the 48516 high-speed steel bit?
Only the single bright-finish HSS drill bit is supplied; cutting fluid or lubricant must be purchased separately for metal drilling applications.
