The Walter 3\/8″ SST Stub Drill Bit (01H124)<\/strong> is an industrial-grade cutting tool engineered for machinists and fabricators who demand rigidity and precision. Unlike standard jobber-length bits, this stub drill (also known as screw machine length) features a shorter flute and overall length. This compact design significantly increases the torsional strength of the bit, making it virtually unbreakable under normal operating conditions. It is the tool of choice when drilling into thin-walled materials like sheet metal, where longer bits tend to flex, wander, or chatter.<\/p>\n At the tip, the bit boasts a 135\u00b0 split point<\/strong> geometry. This aggressive angle allows the drill to bite into the material immediately upon contact, effectively eliminating the “walking” phenomenon common with standard 118\u00b0 points. This self-centering capability means you can often bypass the center-punching step, saving valuable time during production runs. The bit is finished with Walter’s proprietary bronze SST surface treatment<\/strong>, which facilitates smoother chip evacuation and reduces heat generation\u2014the primary enemy of cutting tool life.<\/p>\n One of the standout features of the 01H124 is the Quick Shank<\/strong> design. Drilling tough alloys like stainless steel requires significant torque. Standard round shanks often slip inside the drill chuck under heavy load, damaging both the bit and the chuck jaws. The Quick Shank incorporates engineered flats that lock into the chuck, ensuring positive drive transmission and preventing slippage entirely. This feature, combined with the stub length, makes this bit exceptionally efficient for portable drilling applications where stability is key.<\/p>\n This bit excels in drilling stainless steel, mild steel, and non-ferrous metals<\/strong>. Its rigidity makes it perfect for drilling out spot welds or creating holes in body panels without the risk of snapping the tool. Whether you are working in a tight engine bay, installing rivets in sheet metal, or operating a stationary drill press, the Walter SST Stub Drill delivers consistent, burr-free holes with superior finish quality.<\/p>\n","protected":false},"excerpt":{"rendered":"Precision Drilling for Confined Spaces and Sheet Metal The Walter 3\/8″ SST Stub Drill Bit (01H124) is an industrial-grade cutting tool engineered for machinists and fabricators who demand rigidity and precision.
