Built from K30F-grade solid carbide, it delivers the hardness and wear resistance required for consistent performance in tough materials. The bit features a 140-degree point angle with an X-treme D point type and double point coating, supporting clean entry and extended tool life. With a 12xD flute length-to-diameter ratio and coolant-through capability, it handles deep-hole operations with effective chip evacuation and thermal control. Licensed machinists and tooling professionals are the primary users of this bit.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for a range of hole types including blind holes, cross holes, inclined holes, stack drilling, and through hole drilling. The 8.5 mm diameter and 138 mm flute length make it appropriate for medium-depth drilling operations in production machining environments. Its parallel shank with a 10 mm shank diameter seats securely in standard tool holders conforming to DIN 6535 HA. The web-thinned, tapered web configuration reduces thrust force at the cutting tip, making it practical for both manual and CNC-controlled setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide K30F construction for high hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003e140-degree X-treme D point with double point coating for precise entry and long service life\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip evacuation and heat management in deep holes\u003c\/li\u003e\n  \u003cli\u003e12xD flute-to-diameter ratio enables maximum drilling depth of 123 mm\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces cutting thrust and improves centering\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with parallel shank conforms to DIN 6535 HA standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct tooling selection for CNC machining centers and drill presses accepting parallel shanks per DIN 6535 HA with a 10 mm shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by machinists or tooling technicians in CNC or manual drilling equipment. Ensure the machine spindle and tool holder are powered down and locked out before changing tooling. Verify the shank seats fully and is secured within a DIN 6535 HA-compliant chuck or collet. Activate coolant-through supply before beginning drilling cycles to maintain proper chip clearance and bit temperature.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A6589DPP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.5 mm (0.3346 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: X-treme D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Double Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide (K30F)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\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: 138 mm (5.4331 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 180 mm (7 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Parallel, Non-Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10 mm (0.3937 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 40 mm (1.5748 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 123 mm (4.8425 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.55 mm (0.0609 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length x Diameter Ratio\u003c\/strong\u003e: 12xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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: m7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6535 HA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Blind Hole, Cross Hole, Inclined Hole, Stack Drilling, Through Hole Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\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: 5691061\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51727540715826,"sku":"5691061","price":774.23,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f83f6db570cf5893f3abc19ad3d47c0a.jpg?v=1788679051","url":"https:\/\/voomisupply.com\/products\/walter-titex-5691061-taper-length-drill-bit-8-5mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
