5PC SAE STEP DRILL BIT SET - ATD Tools

The ATD Tools 9200 5-Pc SAE Step Drill Bit Set provides professional technicians with a precise and efficient solution for creating clean, accurately sized holes in various thin materials. Engineered to consolidate numerous hole sizes into five robust bits, this set minimizes tool changes and enhances productivity for automotive, industrial, and general fabrication tasks in both shop and field environments.

Key Features

• Comprehensive SAE Coverage: This set includes five step drill bits encompassing a wide range of common SAE hole sizes, reducing the need for multiple individual twist bits when working with thin-gauge steel, aluminum, plastics, and wood. The bits are made of #4241 High Speed Steel for drilling in various materials.
• Multi-Diameter Capability: Each bit is designed to drill, enlarge, and deburr multiple hole diameters in a single operation, streamlining work on vehicle body panels, brackets, dashboards, and enclosures.
• Clean, Deburred Holes: The unique step geometry features a two-flute design that is engineered to chamfer and deburr the hole as you drill, resulting in a smoother, finished edge that reduces secondary finishing.
• Controlled Drilling in Thin Stock: The stepped profile aids in centering the bit and maintaining round, accurate holes in sheet metal, effectively reducing material grab and distortion.
• Professional-Grade Durability: Constructed from #4241 High Speed Steel for longevity, these step drill bits are built to withstand the rigorous demands of repeated use in automotive repair bays, fleet maintenance facilities, and industrial fabrication shops. They also feature a tri-flat shank design for a secure grip in the chuck, preventing slippage.

Applications

• Automotive Electrical & Accessory Installation: Ideal for drilling and enlarging precise holes in vehicle body panels, dashboards, and firewalls for wiring harnesses, switches, and accessory installations on passenger vehicles, light trucks, and commercial vans.
• Sheet Metal Fabrication: Efficiently creates and sizes openings in sheet metal brackets, HVAC ducting, and light-gauge enclosures for custom work or repairs.
• Electrical Panel Work: Suitable for cutting clean holes in electrical panels, junction boxes, and control cabinets for conduit and fitting integration, ensuring compliance and a professional finish.
• Plastic & Acrylic Modifications: Provides clean edges for openings in plastic and acrylic enclosures, guards, and covers, minimizing post-drilling finishing time and preventing material splintering.
