01W105 - Walter Titanium Coated Multi-Step Drill Bit 3/16-7/8 Inch

Precision Engineering for Industrial Hole Making

The Walter Surface Technologies 01W105 Multi-Step Drill Bit is engineered to deliver superior performance in high-demand industrial environments. Designed specifically for maintenance, repair, and operations (MRO) professionals who require versatility and precision, this tool consolidates multiple drill sizes into a single, robust unit. Capable of creating or enlarging holes ranging from 3/16 inch to 7/8 inch, it eliminates the downtime associated with frequent tool changes. The bit is optimized for use on thin-gauge materials, including stainless steel and sheet metal, up to 1/8 inch in thickness.

At the core of its performance is a specialized titanium coating. This advanced surface treatment significantly increases the surface hardness of the bit, reducing friction and heat generation during the drilling process. Heat is the primary enemy of cutting tools, particularly when working with work-hardening alloys like stainless steel; the titanium coating effectively mitigates this, ensuring the cutting edges remain sharp for a prolonged service life. Furthermore, the bit features a unique two-flute design with wide channels. This geometry is critical for efficient chip evacuation, preventing the build-up of swarf that can cause binding or overheating.

Operational efficiency is further enhanced by the self-centering split point. This feature allows the operator to start drilling immediately without the need for a center punch or a pilot hole, ensuring precise positioning from the very first rotation. The step geometry is ground to provide chatter-free performance, resulting in clean, burr-free holes that often require no secondary finishing. For industrial applications where speed, accuracy, and tool longevity are paramount, the Walter 01W105 stands out as a premier solution.
