It measures 1 inch in overall length with a 0.25-inch flute length and a 0.021-inch diameter straight-cylindrical shank. The 118-degree standard point and two-flute spiral design deliver clean entry and efficient chip evacuation in a compact form factor suited for close-tolerance drilling. Web thinning reduces thrust force on entry. This bit is installed by machinists, tool and die technicians, and precision fabricators working on small-diameter bore applications in metalworking, electronics assembly, and general manufacturing environments.\u003c\/p\u003e\n\u003cp\u003eThe 5999212 is built for drilling operations in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. Its 12xD flute-to-diameter ratio and tapered web configuration make it well suited for through-hole and short blind-hole work in light-gauge and hardened workpiece materials. Maximum recommended drilling depth is 0.25 inches, consistent with its 0.25-inch flute length. The series R18P designation places it within the PRECISION TWIST DRILL R10P-R15P-R18P performance series, which targets general-purpose cutting across a broad range of workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge size 75 (0.021 inches) for close-tolerance small-diameter bores\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose drilling entry\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction supports use in steel, stainless, cast iron, and titanium\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces thrust and improves penetration efficiency\u003c\/li\u003e\n  \u003cli\u003eTwo-flute spiral design promotes chip clearance in short flute-length applications\u003c\/li\u003e\n  \u003cli\u003eANSI-compliant dimensions; bright uncoated finish for direct visual inspection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber length drill bit compatible with standard drill chucks and collet systems accepting a 0.021-inch straight-cylindrical shank.

Secure the shank fully in the chuck or collet and verify minimal runout before commencing a cut. Reduce feed pressure at breakthrough to prevent bit deflection or breakage in thin-section workpieces. Coolant through is not supported on this bit; apply cutting fluid externally when drilling stainless steel, superalloys, or titanium.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 75\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0210 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0210 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 12xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flats\u003c\/strong\u003e: 0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10P-R15P-R18P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04167 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: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5999212\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51696517480754,"sku":"5999212","price":51.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a9595767adf1a1bebcf3507a2874d00_69f92ca8-7dff-47ce-89a0-bf9e5426b38e.jpg?v=1788343474","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999212-jobber-drill-bit-75-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
