Built to DIN 6537 K standards, this bit measures 0.2835 inches in diameter with a 140-degree split point (SU-type) for accurate self-centering entry and reduced thrust. The overall length is 79.00 mm with a 41.00 mm flute length. The straight-cylindrical shank and web-thinned, parallel web configuration make this bit suitable for use in CNC machining centers, drill presses, and screw machine setups where precision and tool life are critical.\u003c\/p\u003e\u003cp\u003eThis drill bit is engineered for cutting cast iron and steel, including high-alloy and hardened steels where a submicron carbide grade is required. The screw machine length format provides added rigidity compared to jobber-length bits, reducing deflection in short-hole drilling. It is a right-hand cut, spiral flute design with a 3xD flute-to-diameter ratio, appropriate for through-hole and blind-hole work in production machining environments. Machinists, tool and die technicians, and maintenance professionals working with ferrous materials will find this bit suited to their applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with submicron carbide grade for extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree SU split point promotes accurate entry and reduces walking on hard surfaces\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web lowers thrust requirements and improves chip evacuation\u003c\/li\u003e\n\u003cli\u003eScrew machine length body provides greater rigidity and reduced deflection versus jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute design with 3xD ratio for effective chip clearing\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 a direct-fit replacement or standard tooling selection for screw machine, CNC, and drill press setups requiring a 0.2835-inch diameter carbide drill in the DIN 6537 K screw machine length format.

Secure the straight-cylindrical shank fully in a precision collet or drill chuck rated for carbide tooling before use. Carbide bits are brittle and susceptible to fracture if subjected to side loads, interrupted cuts without proper support, or improper runout. Verify spindle runout and feed rates are within the tool manufacturer's recommended range before beginning a production run.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2835 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 79.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 41.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4960 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.1890 inches (30.20 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\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: 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, Web-Thinned\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\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.006 to +0.021 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.2500 to 0.3000 inches\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: 5514\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 9055140072000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51747528507698,"sku":"9055140072000","price":167.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1722d1467d4ba478bd1f6fe04876cc3d_6da65313-fb82-4dc8-979d-0248299f551f.jpg?v=1788881950","url":"https:\/\/voomisupply.com\/products\/guhring-9055140072000-carbide-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
