The Walter 01E121 SST+ Drill Bit Kit is a comprehensive solution for industrial drilling applications, offering a versatile range of sizes from 1\/16-inch to 3\/8-inch. Designed for the professional machinist and fabricator, this kit features Walter’s renowned SST+ (Super Speed Tip) geometry. The bits are manufactured from a proprietary blend of High Speed Steel (HSS) and Cobalt, which significantly enhances heat resistance and wear life compared to standard black oxide or titanium-coated bits. This metallurgical composition makes them exceptionally capable when drilling through tough materials like stainless steel, structural steel, and aluminum alloys.<\/p>\n
A standout feature of this series is the exclusive Quick Shank design. On larger sizes within the kit, the shanks are engineered with three precision-ground flats. This design integrates seamlessly with standard three-jaw keyless and keyed chucks, providing a positive lock that completely eliminates bit rotation or “spinning” under high-torque loads. This ensures maximum power transmission from the power tool to the cutting edge, improving efficiency and protecting the drill chuck from damage caused by slippage.<\/p>\n
The drill bits utilize a 135-degree split point geometry. Unlike standard 118-degree points, the split point is self-centering, meaning it begins cutting immediately upon contact with the workpiece. This eliminates the need for pre-punching or pilot holes and prevents the bit from “walking” across the surface, ensuring precise hole placement every time. The heavy-duty web construction adds rigidity to the bit, reducing the risk of snapping during breakthrough or when drilling at slight angles. Packaged in a rugged, impact-resistant index case, the 01E121 kit keeps your tools organized and protected in harsh shop environments.<\/p>\n","protected":false},"excerpt":{"rendered":"Works with all Walter drills.\n\nLightweight.\n\n#1 Brand.","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[2000,2012],"product_tag":[],"class_list":["post-1750504","product","type-product","status-publish","product_cat-abrasives","product_cat-drill-bits-and-carbides","pa_brand-walter","pa_material-high-speed-steel-hss-with-cobalt-blend","pa_packaging-description-1-per-each","pa_packaging-description-1-set","pa_used-to-cut-steel-or-stainless-or-aluminum","first","onbackorder","taxable","shipping-taxable","purchasable","product-type-simple"],"acf":[],"yoast_head":"\n
