Astro Pneumatic Tool Co. - Ach 9445 Titanium Step Drill Bit Set delivers corrosion-resistant titanium coating and stepped cutting geometry for precise, consistent hole sizes in sheet metal and thin materials. The Full Description lists the key step ranges: 1/8"-1/2"; 3/16"-1/2"; 1/4"-3/4", making this set suitable for a wide range of automotive and general fabrication tasks.

Drills And Applications

This step drill bit set is designed for drilling tasks where smooth transitions between hole sizes and minimal burr are important. The stepped design reduces bit changes when enlarging holes, improving workflow speed for technicians and tradespeople. It pairs well with rotary drills in the power tools category for tasks like panel work, bracket installation, and conduit or fitting hole preparation.

Professional Power Tools Features

The titanium finish increases surface hardness and extends bit life under cyclic use compared with plain high-speed steel. Users looking for professional power tools appreciate the combination of durability and geometry control that step drills provide. The 9445 model is a practical choice for crews and shops needing reliable performance from their tooling.

Heavy Duty Automotive Power Tools Compatibility

Specifically relevant to automotive environments, these step drills are compatible with a broad selection of automotive power tools and drill drivers. The provided size ranges cover many common automotive openings and retrofit applications. The set complements other heavy duty automotive power tools in a technician’s kit, reducing downtime and tool swaps.

Grinders And Saws Considerations

While step drills excel for hole making, they are intended to be used with rotary drilling tools rather than grinders or saws. For projects that require cutting or shaping beyond hole enlargement, pair this set with the appropriate grinders or saws from the same power tools category to complete fabrication and finishing tasks efficiently.
