The Walter 01J038 #38 SST Stub Drill Bit<\/strong> is engineered for professionals who demand precision and durability in their metalworking tools. Part of Walter’s renowned SST+ line, this drill bit is specifically designed to tackle the challenges of drilling through sheet metal and tough alloys. The “stub” or screw machine length provides exceptional rigidity compared to standard jobber length bits. This reduced length significantly lowers the risk of deflection and breakage, making it the ideal choice for high-torque applications or when working with hand-held drills where stability can be compromised.<\/p>\n Manufactured from a specialized cobalt blend<\/strong>, this bit offers superior heat resistance and hardness, allowing it to maintain a sharp cutting edge even when drilling through abrasive materials like stainless steel. The addition of a unique bronze SST surface treatment further enhances performance by reducing friction and facilitating smoother chip evacuation. This results in cleaner holes and a longer tool lifespan, reducing the frequency of replacements in high-volume production environments.<\/p>\n One of the standout features of the 01J038 is its split point geometry<\/strong>. This design ensures the bit begins cutting immediately upon contact with the material, eliminating the need for a center punch and preventing the bit from “walking” across the surface. This is particularly beneficial when drilling into rounded surfaces or polished sheet metal. Whether used in a stationary drill press or a portable drill, the Walter #38 SST Stub Drill delivers consistent, reliable performance for MRO and fabrication tasks.<\/p>\nKey Technical Benefits<\/h3>\n
