01H007 - Walter 7/64 Inch SST Heavy-Duty Stub Drill Bit

Industrial-Grade Precision with Walter SST Stub Drills

The Walter 7/64" SST Stub Drill Bit (01H007) represents the pinnacle of drilling efficiency for industrial maintenance, repair, and operations (MRO). Designed to address the common failure points of standard length bits, this stub drill—often referred to as a screw machine length drill—offers superior rigidity and durability. In high-volume production environments or maintenance shops where downtime equates to lost revenue, the reliability of your tooling is paramount. The Walter SST series is engineered with a heavy-duty web and a short flute length, significantly reducing the torsional stress that typically causes longer bits to snap under pressure.

One of the standout features of this drill is its 135° split point geometry. Unlike standard 118° points that tend to "walk" across the surface before biting in, the SST's split point centers immediately upon contact. This feature eliminates the time-consuming step of center punching, streamlining workflow and improving accuracy. For facility managers and procurement specialists, this means faster turnaround times on repairs and fabrication tasks. The self-centering action is particularly beneficial when working with round stock or curved surfaces, ensuring the hole is drilled exactly where intended without marring the surrounding material.

The bit is treated with a unique bronze SST surface coating. This specialized treatment is not merely aesthetic; it serves a critical functional purpose by reducing the coefficient of friction between the tool and the workpiece. Lower friction results in less heat generation, which is the primary enemy of cutting tool life. By keeping the cutting edge cooler, the Walter SST maintains its hardness and sharpness longer, even when drilling through tough materials like stainless steel and other hard alloys. This translates to a lower cost-per-hole and reduced inventory consumption over time.

Ideal for perforating sheet metal, the stub length design minimizes deflection, ensuring rounder, more accurate holes. Whether used in stationary drill presses or portable hand drills, the 01H007 delivers consistent performance. Its compact nature also makes it the tool of choice for drilling in confined spaces where a standard jobber bit simply would not fit. Invest in Walter SST Stub Drills for a robust solution that enhances productivity and safety in your metalworking operations.
