The 140-degree split-point geometry with UR web thinning reduces thrust and centers the drill without a pilot hole. A TiAlN coating adds heat resistance and extends tool life in abrasive, high-temperature cutting conditions. Overall length is 2.0625 inches with a 0.8750-inch flute length. The straight cylindrical shank measures 0.1875 inches in diameter. This bit is specified to DIN standards and is installed by machinists and tool-and-die professionals working in precision drilling applications.\u003c\/p\u003e\u003cp\u003eThe 4500035 is suited for drilling hardened steels, tool steels, and other hardened materials in both production and maintenance machining environments. The slow spiral flute design controls chip evacuation in tough, work-hardening materials and reduces the risk of chip packing. A 4xD flute-to-diameter ratio keeps the bit rigid over its working length. This bit is a single-piece, solid carbide construction with no coolant-through capability, making it appropriate for dry or externally lubricated setups on conventional or CNC drill presses and machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hardened materials\u003c\/li\u003e\n\u003cli\u003e140-degree point angle with UR web thinning reduces entry thrust and self-centers\u003c\/li\u003e\n\u003cli\u003eTiAlN coating provides heat and oxidation resistance for extended tool life\u003c\/li\u003e\n\u003cli\u003eSlow spiral flute geometry controls chip flow in tough, work-hardening alloys\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank at 0.1875 inches fits standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eDIN specification designation for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct substitute for No. 22 wire-size jobber drill bits in solid carbide grade with a 0.1875-inch straight shank, suitable for use in standard drill chucks and collet systems accepting that shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or tooling technicians. Secure the shank fully in the chuck or collet and verify runout before cutting. Ensure the spindle and workpiece are properly fixtured before engaging the drill. Do not exceed the recommended surface footage for solid carbide tooling in the material being drilled, and use external coolant or cutting fluid where the application requires it.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 22\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1570 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Proprietary (UR-Thinned Web)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Slow Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.8750 inches (7\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0625 inches (2-1\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 4xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hardened Materials\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: DIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4500035\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51736908464434,"sku":"4500035","price":49.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5334c430307ca55fa63f5fde7d14e8d1.jpg?v=1788781803","url":"https:\/\/voomisupply.com\/products\/accupro-4500035-no-22-solid-carbide-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
