It measures 0.3701 inches (9.40 mm) in diameter with a 140-degree split point (SU point type) and a web-thinned geometry that reduces thrust and improves centering. The two-flute spiral design with a parallel web configuration promotes efficient chip evacuation. The coated finish extends tool life in abrasive cutting conditions. At 84.00 mm overall length and a 40.00 mm flute length, this stub-length bit offers increased rigidity over jobber-length equivalents. It is intended for use by machinists, toolroom technicians, and production drilling operators.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is optimized for drilling cast iron and steel workpieces, making it well-suited to CNC machining centers, drill presses, and screw machine operations where short, stiff tooling is required. The screw machine length format is standard in high-cycle production drilling where runout control and tool rigidity are critical. The 3xD flute-to-diameter ratio supports drilling depths up to 1.02 inches (25.90 mm) without coolant-through capability. It conforms to DIN 6539 specification, placing it within a standardized tolerance class for straight-cylindrical shank tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron-grade construction for rigidity and wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e140-degree SU split point with web thinning for reduced entry thrust and improved self-centering\u003c\/li\u003e\n  \u003cli\u003eCoated finish extends tool life in cast iron and steel applications\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length format increases rigidity over jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, two-flute spiral geometry for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6539 standard; diameter tolerance +0.006 to +0.021 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use tooling for production drilling setups requiring a straight-cylindrical shank drill bit in the 0.3500 to 0.4000 inch (8.00 to 9.50 mm) diameter range per DIN 6539 Series 1242.

Verify spindle runout before seating the bit, as carbide tooling is sensitive to lateral loading. Power down and lock out the machine before changing tooling. Do not exceed the recommended maximum drilling depth of 1.02 inches without retracting to clear chips, as this bit does not have coolant-through capability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.3701 inches (9.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 84.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 40.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.02 inches (25.90 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: SU (web-thinned)\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\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 (Submicron Grade)\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: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.006 to +0.021 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6539\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1242\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 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: 9012420094000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51733439021362,"sku":"9012420094000","price":241.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eb715281d39207cb26847d1fc80a285a.jpg?v=1788755497","url":"https:\/\/voomisupply.com\/products\/guhring-9012420094000-screw-machine-drill-bit-0-3701-in","provider":"Voomi Supply","version":"1.0","type":"link"}
