Built from high speed steel with a bright, uncoated finish, it features a 135-degree split point and a parabolic flute profile. The web-thinned, tapered web construction reduces thrust during entry and promotes self-centering without a center punch on many materials. With a flute length of 3.625 inches and an overall length of 6 inches, this bit is suited for deeper hole applications where a jobber-length bit falls short. A licensed machinist, toolroom technician, or maintenance mechanic would typically reach for this bit in production and MRO drilling operations.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for general-purpose heavy-duty use across a broad range of workpiece materials including alloy steel, carbon steel, stainless steel, hardened steel, tempered steel, cast iron, malleable iron, aluminum, aluminum alloy, brass, bronze, copper, nickel, titanium, titanium alloy, magnesium, magnesium alloy, and graphite. The taper length body provides additional reach for through-hole work in thicker stock or where a standard jobber length cannot clear the fixture. Right-hand cut only. Meets ANSI standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size number 7 — 0.2010 inches decimal diameter\u003c\/li\u003e\n  \u003cli\u003e135-degree split point promotes self-centering and reduces walking on entry\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry improves chip evacuation in deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers axial thrust and extends tool life\u003c\/li\u003e\n  \u003cli\u003eTaper length body — 3.625-inch flute, 6-inch overall length — for deeper reach than standard jobber bits\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction, bright uncoated finish, ANSI-compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose taper length replacement drill bit compatible with any standard drill press, CNC machining center, or hand-held power drill accepting a straight shank of 0.2010 inches.

Verify spindle speed and feed rate are appropriate for the workpiece material and bit diameter — consult published HSS drilling charts for the specific material being cut. Use cutting fluid or coolant where the material and setup allow, particularly in stainless steel or titanium applications. Inspect the cutting edges and web for wear or chipping before each use; a dull or chipped bit in high-hardness material increases breakage risk and damages the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: QC91P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: Number 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\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\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2010 inches\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Self-Centering\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose, Heavy-Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\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: 5997177\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51712882737458,"sku":"5997177","price":36.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/493f31ed2c78d8c96911c7c32cd9970a_0ac0ea25-b83c-4b64-894c-6008fb64963c.jpg?v=1788489141","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997177-taper-length-drill-bit-7-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
