This obtuse geometry strengthens the cutting tip, reduces cutting forces, and minimizes carbide drill bit \"slioping or walkino\" for improved accuracy and drill life\u003c\/li\u003e\n\u003cli\u003eTialsi Coating For Stainless \u0026amp; Hard Steels：TiAlSi coating represents a significant advancement over conventional AlTiN. It features a substantially higher coating hardness of 3,200 HV compared to AlTiN's 2,600 HV, and an elevated oxidation resistance of 1,300°C. This combination, along with its high coefficient of friction, is engineered to withstand the extreme heat and abrasion encountered when drilling stainless steels and high-hardness steel materials\u003c\/li\u003e\n\u003cli\u003eYFTOOL 2pcs 3\/16 Carbide Drill Bit Set | Precision For Delicate Work：this solid carbide drill bit includes, 3\/8\" engineered for fine and precise drilling. the premium carbide construction ensures exceptional rigidity, guaranteeing tight tolerances within ±0.003mm for demanding applications\u003c\/li\u003e\n\u003cli\u003eOptimized Chip Control \u0026amp; Heat Reduction：the strong pumping effect created by the 30° helix angle can quickly expel long and tough chips out of the hole. this feature, combined with the short chips formed by the 135° point angle, fundamentally solves the problem of chip blockage. smooth chip evacuation removes a large amount of cutting heat, effectively controlling the workpiece temperature, and significantly reducing the work hardening phenomenon common on materials such as stainless steel and hard steel\u003c\/li\u003e\n\u003cli\u003e0.4μm K30 Carbide：the foundation of this carbide drill is a k30 grade carbide with an ultra-fine 0.4-micron grain structure. this delivers two key benefits: extreme wear resistance for a longer tool life and superior strength\/rigidity to prevent deflection and breakage, ensuring consistent precision in every cut\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eFree shipping included. 30-day hassle-free returns.\u003c\/p\u003e","brand":"Augusta Warehouse","offers":[{"title":"Default Title","offer_id":50863211348025,"sku":"AW-B0G357RQL8","price":99.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0833\/2846\/7001\/files\/51Ao1QfXFML.jpg?v=1792479515","url":"https:\/\/augustawarehouse.com\/products\/3-8-tungsten-solid-carbide-drill-bit-for-hardened-steel-stainless-steel-hot-working-steel-metal-cnc-carbide-twist-drill-bits-135-point-angle","provider":"Augusta Warehouse","version":"1.0","type":"link"}
