Attempting to drill stainless steel will overheat the bit, destroying the cutting edge instantly. For stainless steel, premium cobalt-alloy (HSS-Co M35) step bits are required.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What causes the bottom of the hole to be smaller than the top entry hole when drilling thick boards?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: This is due to the stepped pagoda design of the bit. Since each level is only a few millimeters deep, if the material thickness exceeds 5mm, the bit cannot pass completely through to the next step without the preceding step continuing to widen the entry hole, resulting in a stepped, uneven bore.\u003c\/p\u003e\n\n\u003c!-- Recommended System Bundles \u0026 Cross-Linking (Strictly 3 Links, Chinese placeholders inside href) --\u003e\n\u003cdiv style=\"background-color: #fcfcfc; border: 1px solid #e5e5e5; padding: 15px; border-radius: 6px; margin-top: 30px;\"\u003e\n  \u003cp style=\"margin: 0 0 10px 0; font-size: 15px; font-weight: bold; color: #333;\"\u003eRecommended System Bundles \u0026amp; Companion Products:\u003c\/p\u003e\n  \u003cul style=\"margin: 0; padding-left: 20px; font-size: 14px; color: #555;\"\u003e\n    \u003cli style=\"margin-bottom: 8px;\"\u003e\n      \u003cstrong\u003eFor Bucket \u0026amp; Tank Drilling:\u003c\/strong\u003e Use these step bits to drill clean, precise holes on plastic drum walls before mounting our \n      \u003ca href=\"https:\/\/atradesen.com\/collections\/misc-adapters-transition-fittings\/products\/pvc-internal-and-external-thread-repair-insert-g-pt-bsp-male-to-female-reducing-bushing-pipe-fitting-1-2-to-2-atradesen\" style=\"text-decoration: underline; font-weight: bold; color: #0056b3;\"\u003ePVC Male-to-Female Reducing Bushings\u003c\/a\u003e.\n    \u003c\/li\u003e\n    \u003cli style=\"margin-bottom: 8px;\"\u003e\n      \u003cstrong\u003eFor Liquid Dispensing Setup:\u003c\/strong\u003e Create a perfect, watertight outlet seal on your storage container alongside our food-safe \n      \u003ca href=\"https:\/\/atradesen.com\/collections\/misc-adapters-transition-fittings\/products\/water-tank-plastic-faucet-pp-food-grade-valveless-dispenser-tap-for-buckets-storage-tanks-atradesen\" style=\"text-decoration: underline; font-weight: bold; color: #0056b3;\"\u003eWater Tank Food-Grade PP Faucets\u003c\/a\u003e.\n    \u003c\/li\u003e\n    \u003cli style=\"margin-bottom: 0;\"\u003e\n      \u003cstrong\u003eFor Siphon Intake Protection:\u003c\/strong\u003e Enlarge pipe inlets smoothly before connecting our weighted \n      \u003ca href=\"https:\/\/atradesen.com\/collections\/pump-air-pump-accessories\/products\/anti-clogging-filter-suction-head-pom-weighted-intake-strainer-for-pumps-siphons-1-4-3-8-qc-g1-2-thread-6mm-10mm-barb-atradesen\" style=\"text-decoration: underline; font-weight: bold; color: #0056b3;\"\u003eAnti-Clogging Filter Suction Heads\u003c\/a\u003e.\n    \u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Atradesen","offers":[{"title":"4~12mm (5 Steps - Hex Shank)","offer_id":56770043871398,"sku":null,"price":1.85,"currency_code":"USD","in_stock":true},{"title":"4~20mm (9 Steps - Hex Shank)","offer_id":56770043904166,"sku":null,"price":2.68,"currency_code":"USD","in_stock":true},{"title":"4~32mm (15 Steps - Hex Shank)","offer_id":56770043936934,"sku":null,"price":5.65,"currency_code":"USD","in_stock":true},{"title":"6~52mm (13 Steps - 12mm Thick Shank)","offer_id":56770043969702,"sku":null,"price":28.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0739\/2588\/6118\/files\/HSS-4241_High-Speed_Steel_Step_Drill_Bit_Symmetrical_Pagoda_Cone_Drill_for_Wood_Plastic_Thin_Metal_Sheet_4mm_-_52mm_-_Atradesen-001.png?v=1783779215","url":"https:\/\/atradesen.com\/products\/hss-4241-high-speed-steel-step-drill-bit-symmetrical-pagoda-cone-drill-for-wood-plastic-thin-metal-sheet-4mm-52mm-atradesen","provider":"Atradesen","version":"1.0","type":"link"}
