01W005 - Walter Multi-Step Titanium Coated Drill Bit 3/16-7/8 Inch

High-Performance Multi-Step Drilling Solution

The Walter 01W005 Multi-Step Drill Bit represents a pinnacle in efficiency for professionals working with thin-gauge materials. Engineered to streamline the drilling process, this tool allows operators to drill holes ranging from 3/16 inch to 7/8 inch without the downtime associated with changing standard twist drills. The bit is specifically designed for use on sheet metal, stainless steel, and other non-ferrous materials with a thickness of up to 1/8 inch. Its stepped geometry acts as multiple drill sizes in one, making it an indispensable asset for electrical, HVAC, and fabrication applications where varying hole diameters are frequently required.

Durability is a core feature of the 01W005. The tool is treated with a premium titanium coating, which provides a hard, heat-resistant surface that significantly reduces friction during the cutting process. This coating not only protects the cutting edges from premature wear but also facilitates smoother cutting action, allowing the bit to maintain its sharpness far longer than standard high-speed steel alternatives. The reduction in friction is crucial when drilling tough materials like stainless steel, where work-hardening can be a common issue with inferior tooling.

Operational stability is ensured through Walter's advanced flute design. The bit features two wide flutes that effectively evacuate chips from the cutting zone, preventing clogging and heat accumulation. This design minimizes chatter, resulting in perfectly round, burr-free holes that often require no secondary finishing. Furthermore, the bit is equipped with a self-centering split point that bites into the material immediately upon contact. This eliminates the tendency for the bit to "walk" across the surface, removing the need for center punching or pilot holes and ensuring precise placement every time. The shank is designed with flats to ensure a secure grip in the drill chuck, preventing slippage under high-torque loads.
