Built on the DFT series platform, this drill accepts two DFT-style inserts with an insert size code of 0302, delivering a maximum drill diameter of 0.838 inches at a 4xD depth-to-diameter ratio, with a maximum drill depth of 2.75 inches. The body is constructed from steel and features a 3\/4-inch Weldon Flat and Flange shank for secure tool holding. Overall length is 6.25 inches. Coolant-through capability with axial concentric entry supports chip evacuation and tool life in high-feed drilling operations. This tool is installed by machinists and tool room technicians in CNC machining centers and manual drill press setups.\u003c\/p\u003e\u003cp\u003eThe 1522175 is suited for general-purpose drilling in ferrous and non-ferrous materials where indexable insert tooling is preferred over solid carbide for cost-per-hole efficiency. The 4xD ratio makes it appropriate for moderate-depth holes in workpieces where through-coolant delivery is beneficial. The Weldon Flat and Flange shank style is a common interface for side-lock tool holders and milling chucks used in machining centers. The DFT insert platform allows quick insert indexing without removing the drill body from the spindle.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDFT series indexable insert drill accepting 2 DFT0302 inserts for field-replaceable cutting edges\u003c\/li\u003e\n\u003cli\u003e4xD drill depth-to-diameter ratio with 2.75-inch maximum drill depth\u003c\/li\u003e\n\u003cli\u003eCoolant-through design with 1\/8-27 axial concentric entry at both shank end and body side\u003c\/li\u003e\n\u003cli\u003eWeldon Flat and Flange shank at 3\/4-inch diameter for secure clamping in side-lock holders\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction, general-purpose tool performance classification\u003c\/li\u003e\n\u003cli\u003eSteel body construction with 6.25-inch overall length and 4.25-inch body length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with DFT-style inserts using insert size code 0302 (insert size 0.156 x 0.096 inches).

Ensure the spindle is fully stopped and the machine is in a safe locked-out state before inserting or removing the drill body. Verify insert seating and torque the insert lock screw per the insert manufacturer specification using the appropriate T6 Torx driver before cutting. Confirm coolant line connection and flow before initiating the drilling cycle to protect insert life and promote chip evacuation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 0.838 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 2.75 inches\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\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat and Flange\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.0 inches\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: 0302\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 0.156 x 0.096 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Entry Style\u003c\/strong\u003e: 1-Axial Concentric Entry\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Side Coolant Hole Thread Size\u003c\/strong\u003e: 1\/8-27 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank End Coolant Hole Thread Size\u003c\/strong\u003e: 1\/8-27 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Lock Screw\u003c\/strong\u003e: M2-04x4.8T6\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\u003eSeries\u003c\/strong\u003e: DFT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.661 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291503\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 1522175\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740844982578,"sku":"1522175","price":829.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f421924a0d0961fff53aa68389cc4700.jpg?v=1788827810","url":"https:\/\/voomisupply.com\/products\/kennametal-1522175-indexable-insert-drill-4xd-dft","provider":"Voomi Supply","version":"1.0","type":"link"}
