3/8" HSS aircraft extension bit
This 12-inch high-speed steel drill bit carries a surface treatment for added wear resistance. Its 3/8-inch diameter matches a 0.3750 decimal equivalent and the flute runs 3-5/8 inches for deep-hole work. Aircraft extension length makes it suitable for reaching through structural members or thick assemblies.
Check shank fit and material needs
Verify that your drill chuck accepts a straight 3/8-inch shank before ordering. The bit is designed for metal cutting; it is not intended for masonry, concrete or wood-only applications. Ensure the workpiece thickness does not exceed the usable flute length.
