The body is constructed from steel and accepts two DFT-style inserts, with a maximum drill diameter of 0.85 inches (21.59 mm) and a maximum drill depth of 3 inches (76.20 mm), yielding a 4xD depth-to-diameter ratio. The 1 inch Weldon Flat and flange shank provides rigid, positive-drive retention in compatible tool holders. Coolant is delivered axially through a concentric entry with a 1\/4-18 threaded shank-end coolant port, supporting through-coolant capability during deep-hole operations. This drill is intended for installation and use by skilled machining professionals.\u003c\/p\u003e\n\u003cp\u003eThe 1522171 is suited for general-purpose through and blind-hole drilling in production machining environments, including job shop and manufacturing floor applications. Its 4xD depth ratio makes it appropriate for moderate-depth bores where indexable-insert tooling is preferred over solid-carbide drills for cost-of-operation reasons. The straight shank with Weldon Flat and flange engagement fits standard toolholder configurations used on CNC machining centers and drill presses with compatible spindle interfaces. Compatible insert style is DFT, insert size code 0303, with an insert lock screw specification of M2.5-0.45x5.9 T8 drive.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDFT-series indexable insert system accepts two DFT0303 inserts for cost-effective edge replacement\u003c\/li\u003e\n  \u003cli\u003e4xD depth-to-diameter ratio supports drill depths up to 3 inches (76.20 mm)\u003c\/li\u003e\n  \u003cli\u003eMaximum drill diameter of 0.85 inches (21.59 mm) for precision bore sizing\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant capability via axial concentric entry and 1\/4-18 threaded coolant port\u003c\/li\u003e\n  \u003cli\u003eWeldon Flat and flange shank provides positive rotational drive and pullout resistance\u003c\/li\u003e\n  \u003cli\u003eSteel tool body construction for general-purpose durability across common workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with DFT-style indexable inserts, insert size code 0303, and insert designation DFT0303.

Ensure the machine spindle is fully stopped and locked out before mounting or demounting the drill body. Confirm the toolholder bore and retention method are compatible with the 1 inch Weldon Flat and flange shank before assembly. When replacing inserts, use the specified T8 torx key on the M2.5 lock screw and follow the insert manufacturer seating procedure to ensure proper insert positioning before resuming operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 0.85 inches (21.59 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 3 inches (76.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Depth by Diameter Ratio\u003c\/strong\u003e: 4xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 4.5 inches (114.30 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 3 inches (76.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat and Flange Straight Shank\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Inserts\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Style\u003c\/strong\u003e: DFT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Size Code\u003c\/strong\u003e: 0303\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Designation\u003c\/strong\u003e: DFT0303\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 0.156 x 0.116 inches (3.97 x 2.95 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Lock Screw\u003c\/strong\u003e: M2.5-0.45x5.9 T8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Entry Style\u003c\/strong\u003e: Axial Concentric Entry\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank End Coolant Hole Thread Size\u003c\/strong\u003e: 1\/4-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DFT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.28 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291503\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: 1522171\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739770945842,"sku":"1522171","price":832.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/583827b6cee60a9450f96da35a3610e6.jpg?v=1788818677","url":"https:\/\/voomisupply.com\/products\/kennametal-1522171-indexable-insert-drill-4xd-0-75-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
