01W101 - Walter Titanium Coated Step Drill 1/8-1/2 Inch

Precision Drilling with Walter Multi-Step Technology

The Walter 01W101 Multi-Step Drill Bit represents a pinnacle in drilling efficiency for thin-gauge materials. Engineered by Walter Surface Technologies, this tool is designed to address the common challenges faced when drilling into sheet metal, stainless steel, and other thin laminates up to 1/8-inch thick. The core of its performance lies in its advanced geometry and material composition. Unlike standard twist drills that often wander or require a center punch, this multi-step bit features a self-centering point that bites into the material immediately upon contact. This ensures precise hole placement every time, eliminating the risk of marring the workpiece surface due to bit skating.

One of the standout technical features of the 01W101 is its specialized titanium coating. This coating is not merely cosmetic; it significantly increases the surface hardness of the bit, reducing friction and heat buildup during the drilling process. Heat is the primary enemy of cutting tools, particularly when working with work-hardening materials like stainless steel. By mitigating thermal stress, the titanium coating extends the operational lifespan of the bit, allowing for more holes per unit and reducing overall tooling costs. Furthermore, the bit is constructed with two wide flutes. This design choice is critical for efficient chip evacuation. In sheet metal applications, chip clogging can lead to poor surface finish and increased drilling effort. The wide flutes clear debris rapidly, preventing accumulation and ensuring a smooth, chatter-free cutting action.

This single tool offers the versatility of multiple drill sizes, ranging from 1/8 inch to 1/2 inch. This stepped progression allows operators to drill holes of various diameters or enlarge existing holes without the downtime associated with changing bits in a chuck. The steps are precision-ground to provide clean, burr-free entry and exit, often negating the need for secondary deburring operations. For industrial MRO environments where speed and accuracy are paramount, the Walter Multi-Step Drill Bit provides a robust solution that combines durability, precision, and versatility into a single, high-performance package.
