It measures 0.159 inches (wire size #21) in diameter with a 140-degree split point and a right-hand spiral flute geometry. The web-thinned SU point reduces entry force and improves chip evacuation. At 66 mm overall length with a 24 mm flute length and 6 mm straight-cylindrical shank, this short-length drill is built for rigidity in CNC and screw machine applications. Coolant-through capability supports high-speed, deep-hole cycles without recutting chips.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for machining cast iron and steel in precision manufacturing environments. Screw machine length drills are commonly used in CNC turning centers, machining cells, and automatic screw machines where a short, stiff tool is required to maintain tight tolerances. The 3xD flute-to-diameter ratio and DIN 6537 K standard construction make this a suitable option for production drilling where tool life and hole quality are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree SU split point with web thinning for reduced thrust and clean entry\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-speed drilling and chip removal\u003c\/li\u003e\n\u003cli\u003eScrew machine length (short) geometry maximizes rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with regular helix for consistent chip flow\u003c\/li\u003e\n\u003cli\u003eMeets DIN 6537 K standard with m7 diameter tolerance for repeatable fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a high-performance replacement drill bit for applications involving cast iron and steel workpieces where DIN 6537 K screw machine length tooling is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the spindle fully stopped and locked out. Verify that the straight-cylindrical shank is properly seated and clamped in a compatible collet or chuck rated for the shank diameter before starting the spindle. Coolant-through setups require confirmation that the machine coolant supply pressure and flow rate are matched to the tool before running production cycles.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.159 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Size\u003c\/strong\u003e: #21\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 24 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 66 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.706 inches (17.94 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\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 6537 K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 9055100040400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51736239767858,"sku":"9055100040400","price":175.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a421e41410bd1760dd91da72036eb28_4eaf1b3d-cb38-4439-ad4a-67439040ebae.jpg?v=1788776695","url":"https:\/\/voomisupply.com\/products\/guhring-9055100040400-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
