OVERVIEW

Precision Drilling with Walter SST Stub Drills

The Walter 01H018 9/32" SST Stub Drill is an industrial-grade cutting tool engineered for professionals who demand accuracy and durability. Designed specifically for drilling through sheet metal, stainless steel, and other thin-walled materials, this drill bit solves the common issues associated with standard jobber-length bits. The "stub" or screw machine length provides a much shorter flute and overall length, which drastically increases the rigidity of the bit. This added stiffness minimizes the risk of snapping or flexing during operation, ensuring that every hole is round, precise, and burr-free.

At the core of its performance is the 135° split point geometry. Unlike standard 118° points that tend to "walk" or skate across the surface before biting, the Walter SST split point centers itself immediately upon contact. This feature eliminates the time-consuming step of center punching, streamlining your workflow and increasing productivity. The self-centering action is particularly beneficial when working on curved surfaces or polished stainless steel where slipping can cause costly cosmetic damage.

The drill bit is finished with Walter's proprietary bronze SST surface treatment. This specialized coating helps to dissipate heat and reduce friction between the tool and the workpiece. Heat is the primary enemy of cutting tools, especially when working with work-hardening materials like stainless steel. By managing thermal buildup, the SST treatment extends the lifespan of the cutting edge, allowing for more holes per bit and reduced tooling costs over time. Whether used in a stationary drill press or a portable hand drill, the Walter 01H018 delivers consistent, high-performance results in the most demanding industrial environments.

Key Industrial Benefits:

  • Enhanced Rigidity: Short length prevents flexing and breakage.
  • Surface Protection: Bronze coating reduces galling and heat.
  • Efficiency: No center punch required due to split point design.

FAQ

A stub drill is shorter, which makes it much more rigid. This rigidity prevents the bit from flexing or breaking under pressure, making it ideal for hard materials and portable drilling.

No, the 135° split point is self-centering, meaning it will bite into the material immediately without walking, eliminating the need for a center punch.

Yes, the Walter SST line is specifically designed with a bronze surface treatment and heavy-duty geometry to handle tough materials like stainless steel effectively.

The decimal equivalent for a 9/32" drill bit is approximately 0.2812 inches.

Yes, the stub length is actually preferred for hand drills because the shorter bit is less likely to snap if the operator tilts the drill slightly during use.

The bronze SST surface treatment reduces friction and helps dissipate heat, which extends the life of the cutting edge, especially in high-tensile materials.

This drill bit features a 135-degree split point angle.
