What this drill bit does
The Chicago-Latrobe 52464 is a Silver & Deming drill bit built for heavy-duty drilling tasks. Its 118-degree point angle provides reliable centering and efficient cutting across a range of materials. The 1/2 inch reduced shank allows use in standard drill chucks while the high-speed steel body delivers durability for professional workshops and serious DIY users.
Black oxide finish benefits
The black oxide finish reduces friction and resists corrosion during extended use. This coating helps maintain cutting performance by minimising heat buildup and preventing rust on the high-speed steel body. It supports smoother chip evacuation compared to uncoated bits, which is useful when drilling deep holes in metal or wood.
Check your chuck capacity
Verify that your drill accepts a 1/2 inch shank before ordering. The reduced shank design fits standard three-jaw chucks, but smaller capacity drills will not grip it securely. Ensure the workpiece material is compatible with high-speed steel cutting edges and that your drill provides sufficient torque for large-diameter boring.

Questions about this item
How often will the 118 degree point on the high-speed steel bit need resharpening?
Resharpen when the 118 degree point dulls; frequency depends on material hardness and feed pressure.
What limits continuous drilling with the 1/2 reduced shank?
The 1/2 reduced shank can slip in the chuck under high torque before the cutting edges overheat.
How much heat does the black oxide finish generate during all-day drilling?
Black oxide retains some heat; use cutting fluid and pause periodically to keep the bit cool.
