It carries a 0.2717 inch (Letter I) diameter, a 140-degree point angle, and a VA point type with web thinning for improved center cutting. The coated finish extends tool life in abrasive applications. With coolant-through capability and a regular spiral flute geometry, this bit handles heat and chip evacuation in deep-hole work. It is sized in the DIN 6537 K standard and built to a K40 carbide grade. Licensed machinists, tool and die shops, and aerospace maintenance crews are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis drill bit is engineered for primary use in titanium alloy workpieces, where standard HSS tooling falls short. The screw machine length body keeps the tool compact and rigid, reducing deflection in short-reach setups on CNC machining centers, knee mills, and turret lathes. The 3xD flute-to-diameter ratio supports drilling depths up to 0.931 inches (23.65 mm). The straight-cylindrical shank with an 8 mm diameter seats directly in standard ER or drill chuck toolholders without adapters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide K40 grade construction for high hardness and wear resistance in titanium alloy cutting\u003c\/li\u003e\n\u003cli\u003eCoolant-through design channels cutting fluid directly to the tip for heat control at depth\u003c\/li\u003e\n\u003cli\u003eWeb-thinned VA point reduces thrust force and improves hole entry accuracy\u003c\/li\u003e\n\u003cli\u003e140-degree point angle suited for hard, work-hardening materials\u003c\/li\u003e\n\u003cli\u003eDIN 6537 K standard geometry ensures dimensional consistency and toolholder compatibility\u003c\/li\u003e\n\u003cli\u003eCoated finish provides additional lubricity and edge protection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in titanium alloy machining applications.

Secure the shank fully in the toolholder and verify runout before cutting. Coolant-through setups require a coolant-capable spindle and adequate system pressure to realize the full benefit of the through-coolant feature. Inspect the cutting edges and point geometry before each use and replace the bit if chipping or wear is visible.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2717 inches (Letter I)\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: VA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 79.00 mm (approx. 3.11 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 34.00 mm (approx. 1.34 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm (approx. 0.315 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.931 inches (23.65 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCarbide 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\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 8510\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6537 K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: m7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 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: GUHRING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9085100069000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51744642990386,"sku":"9085100069000","price":253.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a78622b57f0f1499a9217c3786e1f66_dab96ca4-4353-4186-a7b3-aef0826e9338.jpg?v=1788859386","url":"https:\/\/voomisupply.com\/products\/guhring-9085100069000-carbide-drill-bit-0-2717-in-letter-i","provider":"Voomi Supply","version":"1.0","type":"link"}
