01W001 - Walter Titanium Coated Step Drill 1/8-1/2 Inch

Precision Engineering for Sheet Metal Applications

The Walter 1/8-1/2 Multi-Step Drill Bit represents a pinnacle in drilling efficiency for thin gauge materials. Engineered for professionals who demand accuracy and longevity, this tool is specifically designed to tackle the unique challenges of drilling sheet metal and stainless steel. Unlike standard twist drills that can grab, wander, or create irregular holes in thin stock, this multi-step bit utilizes a sophisticated geometry to deliver clean, burr-free results every time.

At the core of its performance is the premium titanium coating. This advanced surface treatment drastically increases surface hardness and reduces the coefficient of friction. Consequently, the bit generates less heat during operation—a critical factor when working with stainless steel, which is prone to work-hardening if overheated. The coating ensures that the cutting edges remain sharp significantly longer than uncoated high-speed steel alternatives, providing excellent return on investment for industrial users.

The structural design features two wide flutes that are essential for efficient chip evacuation. In sheet metal drilling, chip buildup can lead to poor surface finish and increased heat; Walter's flute design actively ejects debris to maintain a clear cutting path. Furthermore, the self-centering point anchors the drill immediately upon contact, eliminating the "walking" effect and removing the necessity for a center punch. This feature streamlines the workflow, allowing operators to position and drill with one-handed ease.

Capable of drilling or enlarging holes from 1/8 inch up to 1/2 inch in increments, this single tool replaces a pocketful of standard bits. It is rated for materials up to 1/8 inch thick, making it an indispensable asset for HVAC technicians, electricians, and general maintenance personnel who require versatility without compromising on precision.
