Sized at 0.625 inches (5\/8 inch) in diameter with a 140-degree split point (SU-style), it delivers aggressive penetration with reduced thrust and walking. The two-flute spiral design with web thinning promotes efficient chip evacuation. With an overall length of 115 mm and a flute length of 65 mm, this bit is built for stub-length rigidity. It carries a coated finish and conforms to DIN 6537 K standards, making it a reliable choice for machinists, tool crib managers, and CNC operators working in steel and cast iron applications.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for screw machine operations, CNC machining centers, and short-hole drilling applications in production shops. Primary workpiece materials include cast iron and steel. The whistle notch shank measures 16 mm in diameter, providing positive drive retention in standard toolholders. A maximum drilling depth of 1.622 inches (41.20 mm) covers the majority of stub-depth bores typical in high-volume part runs. The 3xD flute-to-diameter ratio keeps the tool compact and stiff for consistent hole quality at elevated feed rates.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with K40 material grade for wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e140-degree SU point with web thinning reduces entry thrust and eliminates center drilling in many setups\u003c\/li\u003e\n  \u003cli\u003eWhistle notch shank (16 mm diameter) locks positively into compatible toolholders\u003c\/li\u003e\n  \u003cli\u003eCoated finish extends tool life in cast iron and steel cutting applications\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537 K standard for dimensional consistency and interchangeability\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length geometry maximizes rigidity and minimizes deflection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a Series 1184 screw machine length drill for use in CNC machining centers and production drilling equipment that accept a 16 mm whistle notch shank.

Ensure the machine spindle and toolholder are fully de-energized and at a complete stop before changing tooling. Seat the whistle notch shank fully into the holder and verify drive pin engagement before tightening. Do not exceed the maximum drilling depth of 1.622 inches without retracting to clear chips, and always apply appropriate cutting fluid or coolant per shop practice for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 115 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 65 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.622 inches (41.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 16 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Whistle Notch\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\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide (K40 Grade)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\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: m7\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: 1184\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.244 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: 9011840158700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51741944676658,"sku":"9011840158700","price":512.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e256abd260ce3109a80ac0ef39d48190.jpg?v=1788834484","url":"https:\/\/voomisupply.com\/products\/guhring-9011840158700-screw-machine-drill-bit-0-625in","provider":"Voomi Supply","version":"1.0","type":"link"}
