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":{"0":"post-1750504","1":"product","2":"type-product","3":"status-publish","5":"product_cat-abrasives","6":"product_cat-drill-bits-and-carbides","7":"pa_brand-walter","8":"pa_material-high-speed-steel-hss-with-cobalt-blend","9":"pa_packaging-description-1-per-each","10":"pa_packaging-description-1-set","11":"pa_used-to-cut-steel-or-stainless-or-aluminum","13":"first","14":"onbackorder","15":"taxable","16":"shipping-taxable","17":"purchasable","18":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product\/1750504","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/types\/product"}],"wp:attachment":[{"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/media?parent=1750504"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product_brand?post=1750504"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product_cat?post=1750504"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product_tag?post=1750504"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
