Conforming to ANSI code ZCMT12T306 PR1225 and ISO code ZCMT12T306, this insert features a diamond shape with a positive rake angle and a 7-degree relief angle. The PVD-coated PR1225 micrograin carbide grade delivers consistent edge performance when drilling stainless steel and steel workpieces. With four cutting edges and a right-hand cutting direction, it is designed to maximize tool life and reduce cost per hole in production environments. Licensed machinists and CNC operators working in metalworking shops are the primary installers of this insert.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in the KYOCERA DRZ series indexable drill bodies and is suited to both stainless steel and steel workpiece materials. Its ZCMT12 insert style fits applications where a secure, repeatable seat is required in high-feed drilling operations. Primary workpiece material is stainless steel (material code M), with steel (material code P) as the secondary application. It is well suited to production drilling in aerospace, automotive, and general metalworking environments where consistency across multiple cutting edges is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDiamond insert shape with 4 cutting edges for extended tool life and reduced tooling cost\u003c\/li\u003e\n\u003cli\u003ePR1225 micrograin solid carbide grade with PVD coating for performance in stainless steel and steel\u003c\/li\u003e\n\u003cli\u003ePositive rake angle with 7-degree relief angle reduces cutting forces and heat generation\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard CNC spindle orientation\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and ISO standards (ANSI: ZCMT12T306 PR1225, ISO: ZCMT12T306)\u003c\/li\u003e\n\u003cli\u003eDRZ series insert style ensures consistent seating and indexing repeatability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KYOCERA DRZ series indexable drill bodies accepting ZCMT12 style inserts.

Use an appropriate torx or hex key as specified by the drill body manufacturer to achieve proper clamping torque on the insert screw. Inspect the insert pocket seat for chips or damage before seating a new insert, as debris in the pocket can cause premature insert failure or dimensional inaccuracy. Follow the drill body manufacturer guidelines for insert orientation to ensure the cutting edge is correctly positioned for right-hand rotation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: ZCMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: ZCMT12T306 PR1225\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: ZCMT12T306\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: PR1225\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0236 inches (0.60 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2205 inches (5.60 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.5630 inches (14.30 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5039 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1563 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (M)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel (P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DRZ\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.34 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KYOCERA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TKB09474\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA","offers":[{"title":"Default Title","offer_id":51728666263858,"sku":"TKB09474","price":39.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e3ee0a44ff4ec717e9dc3f2b9d8bde4e_16646c51-5ce2-4ae7-a95d-040ef96f9869.jpg?v=1788694629","url":"https:\/\/voomisupply.com\/products\/kyocera-tkb09474-indexable-drill-insert-zcmt12-pr1225","provider":"Voomi Supply","version":"1.0","type":"link"}
