OVERVIEW

Heavy-Duty Precision for Confined Spaces

The Walter 17/64" SST Stub Drill Bit is engineered for industrial professionals who demand reliability and precision when drilling through tough metals. Known in the industry as a "stub" or screw machine length drill, this tool features a shorter overall length and flute length compared to standard jobber drills. This compact design significantly increases the structural rigidity of the bit, making it virtually unbreakable under normal operating conditions. It is the ideal choice for drilling into sheet metal, thin-walled tubing, and other applications where bit flexibility can lead to breakage or inaccuracies.

At the tip, the Walter SST Stub Drill boasts a sophisticated 135° split point geometry. Unlike standard 118° points that require a center punch to prevent "walking" across the workpiece, this split point bites into the metal immediately upon contact. This self-centering feature is critical when working on curved surfaces, such as pipes or automotive body panels, ensuring that every hole is drilled exactly where intended. The aggressive angle also reduces the thrust load required by the operator, allowing for faster penetration with less physical effort.

Durability is further enhanced by Walter's proprietary bronze SST surface treatment. This specialized coating acts as a lubricant and heat shield, reducing friction between the bit and the workpiece. By keeping drilling temperatures lower, the temper of the high-speed steel is preserved longer, extending the life of the cutting edges. Whether you are working with mild steel, stainless steel, or non-ferrous alloys like aluminum, this drill bit delivers clean, burr-free holes with exceptional consistency. Its short stature also makes it a problem-solver for maintenance and repair operations where clearance for a standard drill is limited.

Key Industrial Benefits

  • Breakage Resistance: The short, sturdy profile withstands higher feed pressures without snapping.
  • Precision Starting: No center punch needed thanks to the non-slip 135° split point.
  • Versatile Performance: Excellent results on stainless steel, mild steel, and aluminum.

FAQ

A stub drill (or screw machine length drill) is significantly shorter than a standard jobber drill. This shorter length makes the bit much more rigid, reducing the likelihood of breakage and allowing for higher feed pressure, which is ideal for sheet metal and hard materials.

No, the Walter SST Stub Drill features a 135° split point geometry that is self-centering. It prevents the bit from 'walking' or skating across the surface, allowing you to drill directly without a pilot hole or center punch.

Yes, the Walter SST Stub Drill is specifically designed with a heavy-duty web and bronze surface treatment that makes it excellent for drilling stainless steel, as well as mild steel and non-ferrous metals.

This specific bit has a diameter of 17/64 inches.

The bronze SST treatment acts as a lubricant and heat deflector. It reduces friction between the tool and the workpiece, which minimizes heat buildup and extends the life of the cutting edge.

Absolutely. The stub length is actually preferred for hand drilling because the increased rigidity makes it easier to control and less prone to snapping if the operator's hand wobbles slightly.

It is suitable for a wide range of materials including mild steel, stainless steel, aluminum (non-ferrous metals), and thin-walled sheet metal.
