It features a 4.10 mm diameter, a 140-degree facet point, and GUHRING's proprietary nano-A multi-layer coating, which reduces friction and extends tool life in abrasive applications. With an overall length of 66.00 mm and a 6.00 mm straight cylindrical shank, this bit is sized for use in CNC machining centers, screw machines, and precision drill presses. Right-hand cutting with a regular spiral flute and web-thinned point geometry allows for clean entry and efficient chip evacuation. This tool is designed for machinists and tooling professionals working in production environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling stainless steel and high-temperature alloys where tool longevity and hole quality are critical. The coolant-through design supports internal coolant delivery, making it a strong fit for high-cycle production operations where heat management is essential. It conforms to DIN 6537 K standards and carries a 3xD flute-to-diameter ratio with a maximum drilling depth of 17.85 mm. Typical applications include aerospace component machining, medical device manufacturing, and precision stainless fabrication where tight tolerances are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with nano-A multi-layer coating for extended wear resistance in stainless steel and high-temp alloys\u003c\/li\u003e\n\u003cli\u003e140-degree facet point with web-thinned geometry for reduced thrust and clean hole entry\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal coolant delivery for heat control in high-cycle applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6537 K standard; material grade K40 carbide\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance m7 for consistent, repeatable fit in precision toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a Series 8510 screw machine length drill bit for use in CNC machining centers and drill presses accepting a 6.00 mm straight cylindrical shank.

Ensure the machine spindle and toolholder are fully powered down and at rest before inserting or removing the bit. Confirm the straight shank is fully seated and clamped to the torque specification required by your toolholder manufacturer. When using the coolant-through feature, verify coolant lines are connected and flow is confirmed before beginning the cut cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.10 mm (0.1614 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 66.00 mm (2.5984 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm (0.2362 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 42.00 mm (1.6535 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 24.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 17.85 mm (0.7030 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\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\u003ePoint Type\u003c\/strong\u003e: Facet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: nano-A Multi-layer\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: m7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, High-Temp Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6537 K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 8510\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 9085100041000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51728339468594,"sku":"9085100041000","price":202.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a78622b57f0f1499a9217c3786e1f66_c4994926-8260-4f4d-aa36-9a8c53760488.jpg?v=1788690537","url":"https:\/\/voomisupply.com\/products\/guhring-9085100041000-screw-machine-drill-bit-4-10mm","provider":"Voomi Supply","version":"1.0","type":"link"}
