01H008 - Walter 1/8 Inch SST Stub Drill Bit with 135 Degree Split Point

High-Performance Drilling for Industrial Fabrication

The Walter 01H008 1/8" SST Stub Drill is an essential consumable for industrial environments requiring precision, durability, and efficiency. Engineered specifically for the demands of modern fabrication shops and manufacturing lines, this drill bit addresses the common failure points associated with standard jobber-length bits. The "stub" or screw machine length design significantly reduces the torsional stress applied to the bit during operation. By shortening the flute and overall length, Walter has created a tool with superior rigidity, making it highly resistant to snapping, even under heavy feed pressure or when used in handheld drilling applications where stability can be variable.

One of the standout technical features of this SST drill is its 135° split point geometry. Unlike standard 118° points that often require a pilot hole or center punch to prevent "walking" across the workpiece, the Walter split point bites into the material immediately upon contact. This self-centering capability is crucial for high-volume sheet metal work, HVAC manufacturing, and automotive assembly, where cycle time reduction is a key performance indicator. The precise angle is optimized to cut efficiently through tough materials, including stainless steel, without work-hardening the metal, a common issue with inferior cutting tools.

Thermal management is critical in drilling operations to extend tool life. The Walter 01H008 features a unique Bronze SST surface treatment. This specialized coating serves a dual purpose: it reduces the coefficient of friction between the bit and the workpiece, and it facilitates better chip evacuation. Lower friction means less heat generation, which preserves the temper of the cutting edge for longer periods. This makes the bit particularly effective for drilling through thin-walled substances and non-ferrous metals where clean, burr-free holes are required. For procurement managers and shop foremen, investing in Walter SST Stub Drills translates to reduced downtime for tool changes and lower overall consumable costs per hole drilled.

This drill bit is versatile enough to handle a wide range of materials found in MRO and production settings, including mild steel, stainless steel, and aluminum. Its compact size also allows for drilling in confined spaces where standard drills simply cannot fit, adding to its utility in complex assembly and repair tasks.
