Extra-Long 37/64 in Drill Bit
The Chicago-Latrobe 50602 is a high-speed steel drill bit with an extra-long design for deep-hole drilling. Its 118-degree notched point starts cleanly in general-purpose materials. Black oxide finish adds wear resistance during extended use. This fractional-inch bit suits maintenance and fabrication tasks needing reach beyond standard lengths.
Fits Standard Chucks for Deep Reach
The bit installs in any drill chuck that accepts a 37/64 inch shank, requiring no special adapters. Its 9 inch maximum drilling depth clears thick workpieces or stacked plates in a single pass. The 4xD proportion balances rigidity with the extra length needed for through-holes. Users gain depth without changing tooling or adding extensions.
Black Oxide Finish Reduces Friction
The surface treatment lowers cutting friction and helps eject chips from deep flutes. No separate coating or lubricant is bundled with the bit. The notched point geometry is integral, not an accessory, so there are no extra parts to install or lose. Performance gains come from the bit itself, not from add-on items.

Questions about this item
How deep can the 37/64 in bit drill before the flutes run out?
The flute length allows a maximum drilling depth of 9 in, which is the practical limit before chip evacuation becomes difficult.
Does the black-oxide high-speed steel stay cool during continuous drilling?
Black oxide helps reduce friction, but sustained high-speed use will still generate heat; use cutting fluid and allow cooling pauses.
What shank style does the 50602 bit need to fit my drill?
The bit uses a standard fractional-inch straight shank, so it fits any three-jaw chuck that accepts 37/64 in diameter.
