Built to DIN 6537 K specification, it features a 140-degree split point (SU type) and a web-thinned, parallel web configuration that reduces thrust and improves chip evacuation. At 0.3438 inches (11\/32 inch) in diameter, this bit runs a regular spiral flute pattern with coolant-through capability, making it well suited for production environments where heat management and tool life are critical. It is typically installed and operated by machinists, tool-and-die technicians, and maintenance professionals working with precision drilling equipment.\u003c\/p\u003e\u003cp\u003eThis bit is intended for drilling cast iron and steel in screw machine length applications where a shorter, stiffer tool body is preferred over a jobber-length bit. The 3xD flute-to-diameter ratio and straight-cylindrical shank allow direct mounting in standard drill chucks and collet systems. Coolant-through capability supports both through-coolant and flood-coolant setups on CNC machining centers and manual drill presses operating at appropriate surface footage for carbide tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide submicron-grade construction for extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree SU split point reduces walking and lowers thrust requirements\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web geometry improves chip flow and reduces heat buildup\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-pressure internal coolant delivery\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, regular spiral flute with coated finish for wear resistance\u003c\/li\u003e\n\u003cli\u003eMeets DIN 6537 K specification for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit solid carbide screw machine drill bit for use in standard straight-cylindrical shank drill chucks and collet holders compatible with a 10 mm shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by qualified machinists or tool-and-die technicians using appropriate CNC or manual drilling equipment. Power down and lock out the machine before changing tooling. Ensure the chuck or collet is clean and undamaged before seating the shank. Carbide tooling is brittle and should not be used in machines with excessive runout or spindle play, as lateral loading can cause chipping or fracture.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 11\/32 inches (0.3438 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide (Submicron Grade)\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: SU (Split Point)\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: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 89 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 47 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 44 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, 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 Bit Diameter Tolerance\u003c\/strong\u003e: +0.006 to +0.021 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6537 K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 9055100087300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51748438933810,"sku":"9055100087300","price":258.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a421e41410bd1760dd91da72036eb28_ca5a1e4f-f115-41f6-823d-83ca533a710f.jpg?v=1788893818","url":"https:\/\/voomisupply.com\/products\/guhring-9055100087300-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
