01W011 - Walter 1/4-3/4 Multi-Step Drill

Versatile and Durable Step Drill for Metal Fabrication

Maximize your productivity with the Walter 01W011 Multi-Step Drill Bit, a premium solution for drilling and enlarging holes in sheet metal and stainless steel. This single tool effectively replaces multiple standard twist drills, covering a size range from 1/4" to 3/4". It is an indispensable asset for welders, mechanics, and fabricators who require speed and accuracy when working with thin-walled materials up to 1/8" thick. The stepped construction allows you to drill precise holes of varying diameters without interrupting your workflow to swap out tooling.

One of the standout features of this Walter drill bit is its specialized titanium coating. This surface treatment significantly increases surface hardness and lubricity, which is critical when drilling abrasive or hard metals like stainless steel. The coating acts as a thermal barrier, protecting the underlying high-speed steel from the intense heat generated during drilling. This results in a tool that maintains its cutting edge far longer than uncoated alternatives, ensuring consistent performance even in demanding production environments.

The geometry of the 01W011 is optimized for clean, effortless cutting. It incorporates a self-centering point that prevents the bit from wandering, ensuring that your holes are exactly where you need them. The deep, double-flute design serves two purposes: it quickly clears metal chips from the cutting zone to prevent clogging, and it stabilizes the bit to reduce chatter. The result is a perfectly round hole with minimal burring, often eliminating the need for deburring tools.

Designed for use in portable power drills and drill presses, the shank provides a secure grip in the chuck to prevent slippage under load. The clearly marked steps make it easy to identify when you have reached the desired diameter, giving you total control over the drilling process. Whether you are installing conduit, modifying enclosures, or performing custom fabrication, the Walter Multi-Step Drill Bit delivers the reliability and finish quality that professional tradespeople demand.
