It features a 135-degree split point for self-centering entry without a center punch, and a parabolic flute geometry that promotes fast chip evacuation and reduced heat buildup during deep-hole drilling. The web-thinned, tapered web configuration lowers thrust requirements. This bit is built to heavy-duty grade performance standards and conforms to DIN 340 specifications, making it a reliable choice for production and maintenance drilling in metal fabrication, machining, and general industrial trades.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for through-hole and deep-hole drilling applications across a wide range of materials including alloy steel, carbon steel, stainless steel, hardened steel, tempered steel, cast iron, malleable iron, aluminum, aluminum alloy, brass, bronze, copper, magnesium, magnesium alloy, nickel, titanium, titanium alloy, and graphite. The taper length body gives it extra reach compared to a jobber-length bit, making it practical for stack drilling, angled entry work, and applications where standard-length bits fall short. It is commonly used by machinists, maintenance technicians, and metalworking professionals in shop and field environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point for self-centering start and reduced walking on entry\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry promotes efficient chip evacuation in deep holes\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers drilling thrust and extends tool life\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles a broad range of ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish; no coating to delaminate during high-heat applications\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 340 standard for taper length drill geometry and tolerances\u003c\/li\u003e\n  \u003cli\u003eStraight shank fits standard drill chucks and machine spindles without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 340 taper length replacement or direct-use drill bit compatible with standard straight-shank drill chucks on benchtop drill presses, CNC machining centers, magnetic base drills, and hand-held power drills accepting a 7 mm (0.2756 inch) shank.

Secure the shank fully in the chuck and verify runout before drilling. Power down and de-energize the machine before changing bits. Do not exceed the spindle speed rating appropriate for a 7 mm HSS bit in the material being drilled; consult standard cutting-speed charts for HSS in the target material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: QC91PM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 7 mm (0.2756 inches)\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\u003eTool Application\u003c\/strong\u003e: Self-Centering\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 102 mm (4-1\/64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length to Diameter Ratio\u003c\/strong\u003e: 6xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 156 mm (6-9\/64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7 mm (0.2756 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 54 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool 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\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\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\u003eWeight\u003c\/strong\u003e: 0.083 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: 5997936\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51700404093234,"sku":"5997936","price":38.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0523b926873e5beee59d705109f2aa85_c6283acd-366b-4392-b67b-7bca5332ab60.jpg?v=1788389906","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997936-taper-length-drill-bit-7mm","provider":"Voomi Supply","version":"1.0","type":"link"}
