Drill Bit Size #52 for Precision Work
This Chicago-Latrobe 11176 aircraft extension drill is sized at #52 for precise hole-making in aviation and machining tasks. The 135-degree split point reduces walking and starts cuts cleanly in tough alloys. High-speed steel construction with a black oxide finish resists wear during repetitive drilling. It suits professionals who need accurate, deep-hole capability in a single-pass tool.
Straightforward Chuck Fit and Deep Reach
The drill fits standard chucks that accept its shank, so installation is a simple insert-and-tighten step. Its 28-degree helix angle clears chips efficiently at the maximum drilling depth of 7/8 in. The 4xD length-to-diameter ratio supports straight holes without a pilot, though chip packing can occur if feed pressure is too high. Lubricant and proper speed prevent premature dulling.
Verify Chuck Capacity and Material Match
Confirm your drill chuck accommodates the #52 shank diameter before ordering. The tool is rated for high-performance machining grades, so match it to the workpiece hardness you plan to cut. The black oxide coating handles ferrous metals well but is not optimised for non-ferrous or abrasive composites. Ensure your setup delivers the rigidity needed for a 4xD extension length.

Questions about this item
How do I confirm the drill is cutting correctly after chucking it?
The 135° split point should start on contact without wandering and produce clean chips when drilling to the 7/8 in maximum depth.
What comes in the package and what must I supply?
The box contains the 11176 #52 aircraft extension drill; you provide the drill motor, chuck, cutting fluid and workpiece clamping.
When should I choose this #52 bit over other sizes?
Choose this #52 bit when the job calls for a #52 wire-gauge hole with a 135° point angle and 4×D flute length.
