Manufactured in the SPPX insert style with a square shape and KCU40 grade, it features a PVD-applied TiN and TiAlN dual-layer coating that provides wear resistance and thermal stability at the cutting edge. The inscribed circle measures 15.73 mm (0.6193 inches), with a thickness of 0.2343 inches and a corner radius of 0.80 mm (0.0315 inches). An RHP chipbreaker geometry controls chip flow during drilling. This insert is installed by machinists and tooling specialists running indexable drill bodies in production or job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for use in indexable drill tooling systems requiring SPPX-style inserts with a 15T508 insert size designation. Right-hand cutting direction makes it compatible with standard spindle rotation on CNC machining centers, lathes with live tooling, and dedicated drilling machines. The 5.50 mm hole diameter and 11-degree relief angle are matched to SPPX-compatible drill bodies. It is appropriate for a range of ferrous and non-ferrous workpiece materials where a PVD TiN\/TiAlN-coated carbide grade is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with PVD-applied TiN and TiAlN coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eSPPX insert style, square shape, 15T508 insert size for direct body compatibility\u003c\/li\u003e\n\u003cli\u003eRHP chipbreaker geometry for controlled chip evacuation during drilling\u003c\/li\u003e\n\u003cli\u003e0.80 mm corner radius (0.0315 inches) reduces edge stress at entry and exit\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard CNC spindle rotation\u003c\/li\u003e\n\u003cli\u003e11-degree relief angle matched to SPPX indexable drill body geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement-style SPPX indexable drill insert for use in drill bodies accepting a 15T508 insert size with a 5.50 mm mounting hole diameter.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torx or hex key to the tool body manufacturer's specified seating procedure — do not over-torque the clamping screw. Inspect the insert pocket and clamping surfaces for chips or debris before seating the new insert, and confirm secure clamping before resuming operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SPPX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN and TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: RHP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 15T508\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 15.73 mm (0.6193 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.80 mm (0.0315 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.2343 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 5.50 mm (0.2165 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.035 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: 5534250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51746781233458,"sku":"5534250","price":195.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dda7702778c4871602afceed6889dead_07efc90f-d44b-4d3c-bb7e-42f1a8f1cc57.jpg?v=1788873554","url":"https:\/\/voomisupply.com\/products\/kennametal-5534250-indexable-drill-insert-sppx-kcu40","provider":"Voomi Supply","version":"1.0","type":"link"}
