YG-1 A–Z Letter Stub Drill Bit Set – 26 Piece

This YG-1 26-piece Letter Stub Drill Bit Set includes precision-sized drills from A through Z, covering diameters from 0.234" to 0.413". The letter-size range provides additional hole-size options beyond standard fractional drills, making this set ideal for machining, fabrication, tapping, reaming preparation, and general metalworking applications.
