Built from high speed steel with a bright uncoated finish, it features a 135-degree split point angle that enables self-centering starts without a center punch. The parabolic flute geometry and web-thinned, tapered web configuration promote efficient chip evacuation, reducing heat buildup during deep-hole drilling. At 2.50 mm (0.0984 inches) in diameter with a 6xD flute-to-diameter ratio, this bit is suited for extended-reach drilling where a standard-length bit would fall short. Right-hand cut only. Conforms to DIN 340 specification.\u003c\/p\u003e\n\u003cp\u003eThis taper length drill bit is used in production and maintenance environments where deep holes must be drilled in a wide range of metals without pilot drilling. The longer flute length relative to diameter makes it well suited for through-hole applications in plate stock, structural shapes, and machined components. It installs in standard straight-shank drill chucks on drill presses, CNC machining centers, and hand-held power drills. The non-coolant-through design is appropriate for conventional dry or flood-lubricated setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point for self-centering starts — no center punch required\u003c\/li\u003e\n  \u003cli\u003eParabolic flute with web thinning for aggressive chip removal in deep holes\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction rated for heavy-duty performance\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 340 taper length standard\u003c\/li\u003e\n  \u003cli\u003eStraight shank fits standard drill chucks — no adapter needed\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with bright uncoated finish compatible with a broad range of cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for drilling alloy steel, aluminum, aluminum alloy, brass, bronze, carbon steel, cast iron, copper, graphite, hardened steel, magnesium, magnesium alloy, malleable iron, nickel, stainless steel, steel, tempered steel, titanium, and titanium alloy.

Secure the straight shank firmly before starting the spindle to prevent slippage. Always apply appropriate cutting fluid for the workpiece material to extend tool life and improve hole finish. Inspect the cutting edges for wear or chipping before each use; a damaged split point will reduce self-centering effectiveness and can cause bit breakage in harder materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0984 inches (2.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-7\/16 inches (62.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-47\/64 inches (95.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0984 inches (2.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 33.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length x Diameter Ratio\u003c\/strong\u003e: 6xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy-Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 340\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: QC91PM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 5998052\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51715810361650,"sku":"5998052","price":25.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0523b926873e5beee59d705109f2aa85_7aa56f03-11f1-454c-af69-72f9779a63ae.jpg?v=1788518601","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998052-taper-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
