Chicago-Latrobe 52453 Reduced Shank Drill Bit
This Chicago-Latrobe 52453 drill bit features a 53/64 in diameter and a 118-degree point angle. It is manufactured from high-speed steel with a black oxide finish for durability. The reduced 1/2 in shank allows use in standard drill chucks. It suits metalworking tasks requiring this specific large diameter.
Upgrading from smaller bits or worn high-speed steel
Replace smaller diameter bits when a 53/64 in hole is required for bolts or piping. The jump is worth it when the reduced shank fits existing 1/2 in chucks, avoiding the need for a larger drill press. A worn bit showing poor chip evacuation or walking on steel indicates replacement.
Practical limits of high-speed steel
High-speed steel performs well in mild steel and cast iron but wears faster in stainless or hardened alloys. The 118-degree point suits general-purpose drilling but may walk on very hard surfaces without a pilot hole. Black oxide finish aids lubricity but does not replace cutting fluid in deep holes. Builders needing cobalt or carbide for abrasive materials should select a different substrate.

Questions about this item
Will the 1/2 reduced shank on this 53/64 in bit fit my standard 1/2 in drill chuck?
Yes, the 1/2 reduced shank is designed to fit any standard 1/2 in drill chuck, allowing use with larger diameter bits like this 53/64 in size.
What is the correct way to secure this 118 degree point angle bit so it does not spin in the chuck?
Open the chuck fully, insert the reduced shank completely, and tighten the chuck key firmly on all three jaws to grip the shank flats securely.
How often will I need to resharpen the 118 degree point on this high speed steel bit?
Resharpen the 118 degree point when cutting becomes slow or requires excess pressure; high speed steel holds an edge well but dulls faster in hard steel or high heat.
