Built from solid carbide grade WJ30ET and coated with a multi-layer TiSiAlCrN and AlTiN finish, this bit delivers extended tool life and heat resistance in tough materials. It features a 180-degree flat bottom point, a whistle notch shank with a 0.3937-inch shank diameter, and an overall length of 3.5039 inches. The 11\/32-inch (0.3437-inch decimal) diameter and 2xD flute-to-diameter ratio make it well suited for short, precise holes where rigidity and accuracy are critical. Licensed HVAC, mechanical, and industrial trades use this bit on CNC equipment and drill presses alike.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for use in steel, stainless steel, cast iron, aluminum and other non-ferrous metals, and high-temperature alloys. Its coolant-through design channels cutting fluid directly to the tip, supporting deeper cuts and chip evacuation in difficult workpiece materials. With a maximum drilling depth of 0.8780 inches and a flute length of 1.2598 inches, it is optimized for screw machine length applications where stub-length rigidity is required. Series DC118-02-A1 identifies it within the WALTER-TITEX solid carbide drill family.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide grade WJ30ET construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eMulti-layer TiSiAlCrN and AlTiN coating for heat and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003e180-degree flat bottom point for accurate, flat-bottomed holes\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip evacuation and tool cooling at depth\u003c\/li\u003e\n  \u003cli\u003eWhistle notch shank for secure tool holding in compatible chucks and collets\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute for consistent chip flow in the listed workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with steel, stainless steel, cast iron, aluminum and non-ferrous metals, and high-temperature alloys as stated by the manufacturer.

Ensure spindle speed and feed rate are set per tooling manufacturer recommendations for the specific workpiece material before engaging the cut. Verify coolant-through supply is active and at adequate pressure before drilling to prevent premature tool wear or breakage. Do not use this bit in handheld drills; it is intended for rigid machine tool setups only.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11\/32 inches (0.3437 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5039 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.2598 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3937 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.9685 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.8780 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 180 degrees (flat bottom)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 2xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Whistle Notch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: WJ30ET\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Multi-layer TiSiAlCrN and AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: p7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum and Non-Ferrous, High-Temp Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DC118-02-A1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WALTER-TITEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8221640\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51730115166514,"sku":"8221640","price":360.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/82ee00e4e7ece8eb1a2a58fa83c48636.jpg?v=1788711967","url":"https:\/\/voomisupply.com\/products\/walter-titex-8221640-screw-machine-drill-bit-11-32-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
