Built to Series A3289DPL standards, it features an 8.50 mm cutting diameter with a 140-degree X-treme Plus point geometry that reduces thrust and improves centering on entry. The double coating and web-thinned, tapered web configuration extend tool life in abrasive and hard materials. With a 10.00 mm straight-cylindrical shank and an overall length of 89.00 mm (3.5039 inches), this bit is suited for CNC machining centers and precision drilling applications. Coolant-through capability supports chip evacuation and thermal management at the cutting zone.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for use in steel, stainless steel, cast iron, hard materials, and non-ferrous metals, making it a versatile tool across production and job-shop environments. The screw machine length profile — shorter overall length relative to stub bits — provides added rigidity for tight-tolerance holes. It is appropriate for use in CNC lathes, machining centers, and drill presses where precise hole diameter and depth control are required. The 3xD flute-to-diameter ratio and spiral flute type support consistent chip flow in both through-hole and blind-hole applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction (grade K30F) for rigidity and wear resistance in hard and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003e140-degree X-treme Plus point reduces walking and entry burr on difficult materials\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip evacuation and extends tool life at higher feed rates\u003c\/li\u003e\n  \u003cli\u003eDouble coating provides added surface hardness and lubricity across the flute and cutting edge\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces thrust load and improves penetration in stainless steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eMeets DIN and ISO standards; diameter tolerance m7 ensures consistent fit in standard tool holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard straight-shank tool holders and collet chucks accepting a 10.00 mm shank diameter.

Ensure the machine spindle and tool holder are fully de-energized and at rest before inserting or removing the bit. Secure the straight-cylindrical shank firmly in a collet or drill chuck rated for the shank diameter to prevent runout. When using coolant-through capability, confirm that internal coolant pressure and flow rate are within the machine tool and toolholder manufacturer specifications before initiating a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.50 mm (0.3346 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 89.00 mm (3.5039 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 47.00 mm (1.8504 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 35.00 mm (1.3780 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10.00 mm (0.3937 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 40.00 mm (1.5748 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\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: X-treme Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide, Grade K30F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Double Coating\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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 Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: m7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A3289DPL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Hard Material, Non-Ferrous Metal, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 5537193\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51732550451506,"sku":"5537193","price":264.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/925b8d78831a8c511109460d6a2365cd_f0cc53a5-5a8a-4b1a-8091-b4fe6928ee98.jpg?v=1788744352","url":"https:\/\/voomisupply.com\/products\/walter-titex-5537193-screw-machine-drill-bit-8-50mm","provider":"Voomi Supply","version":"1.0","type":"link"}
