The drill body accepts interchangeable KenTIP FS (KTFS) insert tips, allowing the cutting end to be replaced without removing or resetting the tool body. With a 16 mm shank diameter, an overall length of 141 mm, and a 5xD depth-to-diameter ratio, this body is built for stable, deep-hole drilling in CNC machining centers and turning centers where repeatability and rigidity are critical. Through-coolant capability is included, supporting chip evacuation and thermal management at the cutting zone.\u003c\/p\u003e\n\u003cp\u003eThis drill body is suited for production and job-shop environments where high-volume hole-making demands consistent insert indexing and minimal setup time. The KTFS toolholder style integrates directly with compatible KENNAMETAL KenTIP FS insert tips. Typical applications include drilling in steel, cast iron, stainless, and other machineable alloys on vertical and horizontal machining centers. The 88.80 mm flute length and 49.00 mm shank length provide the geometry needed for 5xD depth operations with adequate chip clearance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5xD drill depth-to-diameter ratio for deep-hole capability in a single pass\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank for direct clamping in standard ER or hydraulic chuck toolholders\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design delivers coolant directly to the cutting zone for chip flushing and heat control\u003c\/li\u003e\n  \u003cli\u003eKTFS toolholder style accepts KenTIP FS series interchangeable insert tips\u003c\/li\u003e\n  \u003cli\u003e16 mm shank diameter with 141 mm overall length for rigid reach in machining center spindles\u003c\/li\u003e\n  \u003cli\u003eIndexable tip design reduces tooling cost compared to solid carbide drills of equivalent depth\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with KENNAMETAL KenTIP FS (KTFS) series interchangeable drill tip inserts.

Ensure the machine spindle is fully stopped and the tool magazine or turret is in a safe position before mounting or removing the drill body. Clamp the straight shank securely in a properly sized collet chuck, hydraulic chuck, or milling chuck to the torque specifications of the workholding system manufacturer. When connecting through-coolant, confirm the spindle coolant circuit is compatible and that coolant pressure and flow rate are within the machine and toolholder specifications before cutting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KenTIP FS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: KTFS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 16.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 141 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 88.80 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 49.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Depth by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 10.24 x 2.36 x 2.36 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.277 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23153308\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6371981\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51742495277362,"sku":"6371981","price":468.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cb9228038cf77186b0ee73ba2392db3c_b9a39e6a-36b5-404b-8031-b9beac81c608.jpg?v=1788837798","url":"https:\/\/voomisupply.com\/products\/kennametal-6371981-kentip-fs-indexable-drill-body","provider":"Voomi Supply","version":"1.0","type":"link"}
