Built from high speed steel with a titanium nitride (TiN) coating, it offers improved surface hardness and extended tool life compared to uncoated HSS. The bit measures 8.5 mm (0.3346 inches) in diameter with an overall length of 4-19\/32 inches and a parabolic flute geometry that promotes efficient chip evacuation. A 130-degree point angle suits modern CNC and hand-held drilling applications, and the web-thinned, tapered web reduces entry force at the cutting tip.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is optimized for aluminum and similar non-ferrous materials, as well as general-purpose applications in plastics and some steels, consistent with its K, N, and P workpiece material codes per DIN 338. It is well suited to machine shops, maintenance facilities, and production environments where a reliable jobber-length drill is needed in the 8.0 mm to 9.0 mm diameter range. The straight-cylindrical shank fits standard drill chucks and collet systems without modification. Series 652 represents a high-performance tier within the GUHRING catalog, conforming to DIN 338 dimensional standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiN coating increases surface hardness and reduces built-up edge on aluminum and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eParabolic flute profile improves chip flow and reduces heat buildup at depth\u003c\/li\u003e\n  \u003cli\u003e130-degree point angle for aggressive penetration and reduced walking on entry\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers thrust force at the cutting tip\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders up to 0.3346 inches\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 338 for consistent jobber-length dimensional compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 338 jobber-length replacement or direct-use drill bit for standard drill chucks and collet systems accepting a 0.3346-inch straight-cylindrical shank. Suitable for use in CNC machining centers, drill presses, and hand-held power drills. Primary workpiece material codes K, N, and P indicate suitability for aluminum, non-ferrous metals, and plastics.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis drill bit is installed and serviced by machinists, tool-and-die technicians, and maintenance mechanics. Secure the shank fully in the chuck or collet to the recommended grip depth before operation; partial engagement increases runout and reduces tool life. Confirm spindle speed and feed rate are appropriate for the workpiece material and drill diameter before starting the cut. Inspect the cutting edges and TiN coating condition before each use and replace the bit if chipping or coating loss is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.5 mm (0.3346 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-19\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.45 inches (62.25 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3346 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 42.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\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: Parabolic\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\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum (K, N, P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.022 to 0.000 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 652\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 9006520085000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51728221438258,"sku":"9006520085000","price":59.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bf5bec2810bd81ff5a0d88e0ea634736.jpg?v=1788689783","url":"https:\/\/voomisupply.com\/products\/guhring-9006520085000-jobber-drill-bit-8-5mm-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
