#5 unibit 1/4-1 3/8 - Hanson

The Hanson #5 Unibit (Model 10235) is a robust step drill bit designed for professional technicians and mechanics who require efficient, precise hole creation. This single, versatile tool streamlines your workflow by drilling multiple, burr-free hole sizes, eliminating the need for numerous individual bits. It is engineered for superior durability and consistent results across a range of demanding automotive and industrial tasks.

Key Features

• Multi-Diameter Versatility: This single step drill bit replaces up to 12 individual twist drill bits, allowing for the creation of clean holes in 1/4", 5/16", 3/8", 7/16", 1/2", 9/16", 5/8", 11/16", 3/4", 13/16", 7/8", and 1-3/8" diameters.
• Burr-Free Hole Creation: The engineered step geometry produces precise, clean holes in materials up to 1/8 inch thick, reducing the need for post-drilling deburring and ensuring a smooth finish.
• Durable High-Speed Steel Construction: Constructed from high-speed steel, this Unibit offers extended tool life, superior wear resistance, and reliable performance in demanding professional environments.
• Clear, Permanent Size Markings: Permanently etched diameter markings on each step ensure quick and accurate size selection during operation, even after extensive use.
• Self-Starting SpeedPoint Tip: The SpeedPoint tip enables faster initial penetration and helps prevent the bit from "walking" on the material, eliminating the need for center punching.

Applications

The Hanson #5 Unibit is an indispensable tool for a wide array of professional applications. In automotive settings, it is ideal for precise tasks such as enlarging existing holes for custom wiring installations, accurately mounting sensors, modifying body panels, and performing general maintenance without material distortion. Industrially, this step drill bit excels in electrical panel work, HVAC installations, general fabrication projects, and other applications requiring clean, precise holes in materials like sheet metal, conduit boxes, or plastic enclosures. Its robust design allows for effective drilling in ferrous and non-ferrous metals, plastics, and wood composites.
