The Walter SST+ Stub Drill Bit #29 (01J029)<\/strong> is engineered to solve the common frustrations associated with drilling hard metals and thin gauge sheets. Known for its exceptional durability, this drill bit features a premium cobalt blend construction that withstands high temperatures and stress, making it the superior choice for drilling stainless steel, mild steel, and non-ferrous metals. Unlike standard jobber length bits, the stub (or screw machine) length provides maximum rigidity, significantly reducing the risk of snapping or breaking under pressure.<\/p>\n Accuracy is paramount in professional fabrication, and the Walter SST+ delivers with its advanced split point design. This geometry allows the bit to self-center immediately upon contact with the workpiece, eliminating the “walking” or skating effect often seen with standard bits. This feature removes the need for pre-punching, saving you time and effort on every hole. The specialized bronze SST surface treatment further enhances performance by reducing friction and promoting efficient chip evacuation, ensuring a cleaner hole and cooler operation.<\/p>\n While versatile enough for various applications, this stub drill excels in sheet metal work. The short flutes and overall compact length offer the stability needed when drilling through thin walls or round surfaces where vibration can be an issue. Whether you are using a portable hand drill in the field or a stationary machine in the shop, the Walter 01J029 provides the consistency and longevity required for industrial maintenance, repair, and fabrication tasks.<\/p>\nPrecision and Speed<\/h3>\n
