Rack-A-Tiers High Grade 12-Step Cobalt Step Bit

The Rack-A-Tiers High Grade 12-Step Cobalt Step Bit is a professional-grade drill bit designed to create multiple hole sizes with a single tool, making it ideal for electricians, installers, and technicians working with sheet metal and electrical enclosures. Featuring 12 precision-cut steps, the bit allows users to drill or enlarge holes in a wide range of diameters without constantly changing drill bits.

Manufactured from high-grade cobalt steel, this step bit offers exceptional durability, heat resistance, and wear resistance when drilling through materials such as steel, sheet metal, electrical boxes, plywood, acrylic, and plastic laminates. The cobalt construction helps maintain a sharp cutting edge for longer life and reliable performance on demanding job sites.

Step drill bits are especially useful for panel work and knockout enlargement, providing clean, accurate holes with minimal burrs. The stepped design gradually increases hole diameter as the bit advances, allowing installers to easily reach the exact hole size needed while maintaining control and precision.

Designed for use with standard drills or drill presses, this bit is a popular choice for electrical, low-voltage, HVAC, and metal fabrication applications where multiple hole sizes are commonly required.
