Built to Series 8520 and conforming to DIN 6537 K, this bit features a 140-degree split point with web thinning and HF point geometry that reduces thrust and improves entry accuracy. At 0.3438 inches (11\/32 inches) in diameter, it runs a regular spiral flute with a 3xD flute-to-diameter ratio and a straight-cylindrical shank. Internal coolant-through capability allows cutting fluid delivery directly to the tip, making it well suited for high-cycle production drilling where heat management is critical. Licensed machinists and tool-room technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for production and precision machining applications, with titanium alloy listed as the primary workpiece material. Its screw machine length body keeps rigidity high in short-reach setups such as CNC machining centers, turret lathes, and gang-drilling fixtures. The coated solid carbide construction and web-thinned HF point make it a strong choice where hole quality and tool life matter in difficult-to-machine alloys. The 2-margin design supports accurate hole geometry and reduced wandering on entry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction rated to DIN 6537 K and Material Grade K40 for hardness and wear resistance in tough alloys\u003c\/li\u003e\n  \u003cli\u003e140-degree HF split point with web thinning reduces thrust load and improves self-centering on entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design delivers cutting fluid directly to the cutting edge for heat control in deep or high-cycle drilling\u003c\/li\u003e\n  \u003cli\u003eCoated finish extends tool life and reduces built-up edge when machining titanium alloy and similar materials\u003c\/li\u003e\n  \u003cli\u003e3xD flute ratio with regular spiral and 2-margin geometry supports straight, accurate holes\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders without an adapter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification replacement or direct tooling selection for screw machine length drill bit applications in CNC machining centers, turret lathes, and similar setups requiring a straight-cylindrical shank bit in the 0.3000 to 0.3500 inch diameter range, with titanium alloy as the rated primary workpiece material.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or toolroom technicians familiar with carbide tooling. Ensure the spindle and tool holder are fully de-energized and at a complete stop before changing tooling. Carbide is brittle  -  avoid side-loading, interrupted cuts without proper feed adjustment, or dropping the bit on hard surfaces. Verify coolant-through lines are clear and pressure is correct before running at production feeds and speeds.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.3438 inches (11\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 89.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 47.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.3350 inches (33.91 mm)\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: HF\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Margins\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: K40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium Alloy\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: m7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 8520\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6537 K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.068 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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9085200087300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51739873870130,"sku":"9085200087300","price":303.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b012925f4b2d2c88d3a961fb4c3b97ad_103be779-ca91-49d7-9693-c641b7ecc4ee.jpg?v=1788819908","url":"https:\/\/voomisupply.com\/products\/guhring-9085200087300-screw-machine-drill-bit-0-3438-in","provider":"Voomi Supply","version":"1.0","type":"link"}
