01H108 - Walter 1/8-Inch SST Stubby Drill Bit with Hex Shank

High-Performance Drilling for Thin-Walled Materials

The Walter 01H108 1/8" Hex SST Stub Drill is an expertly engineered cutting tool designed to address the specific challenges of drilling into sheet metal, thin-walled profiles, and confined spaces. Unlike standard jobber-length bits, this stub drill features a shortened flute and overall length, which dramatically increases the torsional rigidity of the tool. This structural stability minimizes deflection and vibration, significantly reducing the likelihood of bit breakage even under heavy feed pressure.

Manufactured with Walter's proprietary bronze SST surface treatment, this drill bit exhibits enhanced heat resistance and lubricity, allowing for smoother chip evacuation and extended tool life when working with tough materials like stainless steel and non-ferrous metals. The bit is equipped with a precision-ground 135° split point. This self-centering geometry engages the material immediately upon contact, eliminating the "walking" or skating effect common with standard 118° points. This feature removes the need for pre-punching, streamlining the fabrication process and ensuring accurate hole placement every time.

The integration of a hex shank is a critical feature for modern industrial workflows. It allows for rapid tool changes and ensures a positive drive engagement that prevents the bit from spinning inside the chuck, a common issue with round shanks in high-torque applications. Whether utilized in stationary drill presses or portable power tools, the Walter Hex SST Stub Drill delivers consistent, burr-free performance. It is particularly effective for drilling round surfaces where stability is paramount.

Technical Specifications

This tool is optimized for efficiency, allowing operators to drill more holes in less time due to its aggressive cutting geometry and durable construction. The compact design not only enhances durability but also permits drilling in areas with limited clearance, making it an indispensable asset for MRO professionals and metal fabricators.
