It accepts a fixed pilot insert and two nonpilot inserts secured by screw-style holding, delivering a maximum drill diameter of 57.15mm (2.25 inches) with a 21mm (0.8268 inch) pilot drill diameter. The head length measures 30mm (1.181 inches), with a head length to pilot tip of 34.5mm (1.3583 inches). Coolant-through capability is built in, supporting effective chip evacuation and thermal management at depth. The FDS56 head connection interfaces with compatible KSEM Plus modular shanks. Installation is performed by machining professionals in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis drill head is designed for modular drill systems used in metal-cutting operations across aerospace, automotive, energy, and general machining industries. It is suited for through-coolant drilling setups where hole quality and tool life are critical. The KSEM Plus platform targets applications requiring precise pilot guidance and the flexibility of indexable insert replacement without removing the full drill assembly from the machine spindle.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMaximum drill diameter of 57.15mm (2.25 inches) for large-diameter hole making\u003c\/li\u003e\n  \u003cli\u003eFDS56 head connection for secure, repeatable modular shank interface\u003c\/li\u003e\n  \u003cli\u003eFixed pilot insert design with screw-held nonpilot inserts for rigid cutting geometry\u003c\/li\u003e\n  \u003cli\u003eAccepts 2 nonpilot inserts for balanced cutting action\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip flushing and heat control in deep-hole operations\u003c\/li\u003e\n  \u003cli\u003eIncludes insert screw and wrench for field insert changes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with KENNAMETAL KSEM Plus modular drill shanks equipped with FDS56 head connections.

Disengage machine spindle power and release any stored energy before handling or changing inserts. Use only the supplied wrench and insert screw when seating inserts to avoid cross-threading or improper torque. Ensure coolant ports are clear and aligned with the shank coolant circuit before spindle engagement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KSEM Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Connection\u003c\/strong\u003e: FDS56\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 57.15mm (2.25 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Drill Diameter\u003c\/strong\u003e: 21mm (0.8268 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 30mm (1.181 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length to Pilot Tip\u003c\/strong\u003e: 34.5mm (1.3583 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Nonpilot Inserts\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Type\u003c\/strong\u003e: Fixed Pilot Insert\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Insert Screw, Wrench\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.7 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291500\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: 3794937\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51738632651058,"sku":"3794937","price":1995.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/74e9c1f492163f5b18206c31c427500e_369f8ede-5b93-4c62-b9ed-de466f68b4ce.jpg?v=1788802100","url":"https:\/\/voomisupply.com\/products\/kennametal-3794937-ksem-plus-pilot-insert-drill-head","provider":"Voomi Supply","version":"1.0","type":"link"}
