It accepts KSEM0500 insert tips at an insert seat size C, covering a drilling diameter range of 12.7 to 13.2 mm (0.5000 to 0.5197 inches). The body features a 19.05 mm straight-cylindrical shank and an overall length of 130.18 mm (5.1252 inches). Through-coolant capability is built in via a 3.50 mm (0.1378 inch) coolant hole, supporting chip evacuation and tool life at elevated feed rates. This tool body is sized for machining centers and CNC lathes in production shop environments and is installed by machinists and tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThe 1786056 drill body is suited for high-volume production drilling in ferrous and non-ferrous materials where repeatable hole quality is required. The replaceable-tip design eliminates the need to replace the full drill body when the cutting edge wears, reducing tooling cost per hole. With a 5xD depth-to-diameter ratio and a maximum drill depth of 63.5 mm (2.5000 inches), it handles moderate deep-hole applications in a single pass on properly configured machining centers. The 19.05 mm straight-cylindrical shank interfaces with standard ER or hydraulic toolholders commonly found in CNC machining setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReplaceable-tip design using KSEM0500 inserts, insert seat size C\u003c\/li\u003e\n  \u003cli\u003eDrilling diameter range: 12.7 to 13.2 mm (0.5000 to 0.5197 inches)\u003c\/li\u003e\n  \u003cli\u003e5xD depth-to-diameter ratio with a maximum drill depth of 63.5 mm (2.5000 inches)\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant capability via 3.50 mm coolant hole for effective chip removal\u003c\/li\u003e\n  \u003cli\u003e19.05 mm straight-cylindrical shank for broad toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eOverall length of 130.18 mm (5.1252 inches) with a flute length of 76.45 mm (3.0098 inches)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with KSEM0500 series replaceable drill tip inserts at insert seat size C.

Seat the insert tip securely according to the torque requirements specified in the KENNAMETAL KSEM tooling documentation included with the insert. Verify coolant ports are clear and coolant pressure is appropriate for the application before running. Do not exceed the recommended depth or feed parameters for the insert grade in use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KSEM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Drill Diameter\u003c\/strong\u003e: 12.70 mm (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 13.20 mm (0.5197 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 63.50 mm (2.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Depth by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 130.18 mm (5.1252 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 76.45 mm (3.0098 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 19.05 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Hole Diameter\u003c\/strong\u003e: 3.50 mm (0.1378 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Style\u003c\/strong\u003e: KSEM0500\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3241 pounds\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: 1786056\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51742900683058,"sku":"1786056","price":566.81,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/901cb0b8d815ccd294bc1b35aba324d7_423334bf-9c14-4e05-abf8-b849ac724cdc.jpg?v=1788840400","url":"https:\/\/voomisupply.com\/products\/kennametal-1786056-replaceable-tip-drill-ksem-series","provider":"Voomi Supply","version":"1.0","type":"link"}
