The Walter 01J025 #25 SST+ Stub Drill Bit<\/strong> is engineered for the most demanding industrial environments. When precision and durability are non-negotiable, this cobalt-blended drill bit delivers superior results. Designed specifically for drilling through tough materials such as stainless steel, mild steel, and non-ferrous metals, the SST+ series stands out as a top-tier choice for maintenance, repair, and fabrication professionals.<\/p>\n One of the primary challenges in drilling sheet metal and hard alloys is bit breakage. The Walter SST+ addresses this with its stub length design<\/strong>. By shortening the overall length and flute length, the bit maintains maximum rigidity. This structural integrity allows operators to apply the necessary feed pressure without the bit flexing or snapping, a common issue with jobber-length bits in portable drilling applications. The increased rigidity also contributes to more accurate hole sizing and roundness.<\/p>\n Efficiency is key in any workshop. The 135\u00b0 split point geometry<\/strong> of the 01J025 eliminates the need for center punching. The bit self-centers immediately upon contact, preventing “walking” or skating across the workpiece surface. This feature not only saves time but also protects the finish of your materials. Combined with Walter’s exclusive bronze SST surface treatment, which facilitates chip evacuation and reduces heat friction, this drill bit ensures a longer service life and cleaner cuts every time.<\/p>\nKey Industrial Benefits<\/h3>\n
