Built to DIN 6537K standards and coated with FIREX, it delivers extended tool life and reliable hole quality in tough workpiece materials. The 5\/8 inch diameter bit features a 140-degree split point (SU geometry) with web thinning for reduced thrust force at entry. Overall length is 4.5276 inches (115 mm) and the tool weighs approximately 0.1 pounds. Licensed machinists, tool-and-die professionals, and mechanical contractors working with production drilling equipment are the primary users of this bit.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for production and maintenance drilling in cast iron and steel. The screw machine length (stub) profile is a common choice for CNC machining centers, drill presses, and screw machines where rigidity and minimal runout are critical. The 3xD flute-to-diameter ratio and tapered web configuration support efficient chip evacuation at moderate-to-high spindle speeds. Coolant-through capability allows internal coolant delivery to the cutting zone, making it effective for deep-hole and high-feed-rate cycles in ferrous metals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with FIREX coating for heat and wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e140-degree SU split point with web thinning reduces entry thrust and improves centering accuracy\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports internal coolant delivery for thermal management at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 0.6299 inch (16.00 mm) diameter for secure chuck or collet holding\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length provides increased rigidity compared to jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 6537K specification using DK460UF carbide grade for consistent dimensional tolerance (+0.007 to +0.025 mm)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in cast iron and steel workpieces.

Ensure the machine spindle and chuck or collet are clean and within runout tolerance before seating the shank. Carbide tooling is brittle — avoid side loading, interrupted cuts beyond the tool rating, or dropping the bit on hard surfaces. Always confirm coolant flow is active before initiating a coolant-through drilling cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5276 inches (115 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.5591 inches (65.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.6220 inches (41.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.6299 inch (16.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.9685 inches (50.00 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 (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: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCarbide Grade\u003c\/strong\u003e: DK460UF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: FIREX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.007 to +0.025 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\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\u003eSeries\u003c\/strong\u003e: 5510\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 9055100158700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51735542923570,"sku":"9055100158700","price":718.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a421e41410bd1760dd91da72036eb28_7b1b7388-9e6d-463d-ac65-71f1a92d0adb.jpg?v=1788772950","url":"https:\/\/voomisupply.com\/products\/guhring-9055100158700-screw-machine-drill-bit-5-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
