01H017 - Walter 17/64 Inch SST Stub Length Drill Bit - 135 Degree Split Point

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.
