The Astro Pneumatic ONYX 7-Piece TurboStep Aircraft Extension Length Drill Bit Set (AST-TS7) delivers superior drilling performance across a wide range of demanding applications. Featuring a patented spiral-fluted stepped-tip design, these bits outperform conventional drill bits in nearly all materials, including hard alloys, sheet metal, and imperfect or difficult-to-start surfaces. Each bit is precision ground from heat-treated M2 High Speed Steel and finished with an Onyx oxide coating to prevent chip build-up and extend service life. At a full 12 inches in length, these aircraft-standard bits provide the extended reach needed to access tight spaces or penetrate extra-thick material with confidence.
