It accepts KSEM1438 inserts at seat size 10, allowing tip changes without removing the body from the spindle. The drill covers a diameter range of 36.53 to 37.51 mm (1.4382 to 1.4768 inches) and reaches a maximum drill depth of 111 mm (4.37 inches) at a 3xD depth-to-diameter ratio. Overall length is 285.75 mm (11.25 inches). Through-coolant delivery is standard, supporting extended tool life and chip evacuation in deep-hole operations. Licensed machinists and CNC operators in production machining environments are the primary installers.\u003c\/p\u003e\u003cp\u003eThis drill body is suited for production machining centers running deep-hole operations in ferrous and non-ferrous materials where repeatable hole quality and fast insert indexing are required. The Weldon flat shank with a 38.1 mm (1.50 inch) diameter provides positive drive and secure seating in compatible tool holders. Coolant is delivered through the body via NPT-threaded ports: a 1\/4-18 shank-end port and a 1\/8-27 body-side port, giving shops flexibility in coolant routing configuration. The 171.96 mm (6.77 inch) flute length supports chip clearance throughout the full depth range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDiameter range: 36.53 to 37.51 mm (1.4382 to 1.4768 inches) using seat size 10 KSEM1438 inserts\u003c\/li\u003e\n\u003cli\u003e3xD depth-to-diameter ratio with a maximum drill depth of 111 mm (4.37 inches)\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design with NPT-threaded body-side (1\/8-27) and shank-end (1\/4-18) coolant ports\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank, 38.1 mm diameter, for positive rotational drive in standard tool holders\u003c\/li\u003e\n\u003cli\u003eFlute length of 171.96 mm (6.77 inches) promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eReplaceable-tip system allows insert changes without body removal, reducing downtime\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with KSEM1438 inserts at insert seat size 10.

Confirm tool holder compatibility with the 38.1 mm Weldon flat shank before mounting. Coolant port connections should be verified for proper thread engagement using NPT-rated fittings before operation. Follow the tooling manufacturer's recommended insert clamping procedure when indexing or replacing KSEM1438 tips.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Drill Diameter\u003c\/strong\u003e: 36.53 mm (1.4382 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 37.51 mm (1.4768 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 111 mm (4.37 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth-to-Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 285.75 mm (11.25 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 171.96 mm (6.77 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 38.1 mm (1.50 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Insert Style\u003c\/strong\u003e: KSEM1438\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KSEM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Hole Thread Type\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Side Coolant Hole Thread Size\u003c\/strong\u003e: 1\/8-27\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\u003eWeight\u003c\/strong\u003e: 4.42 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291502\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: 1616110\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":67634843582770,"sku":"1616110","price":1060.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1fda3da92381790128ccd27066bf0192.jpg?v=1790450424","url":"https:\/\/voomisupply.com\/products\/kennametal-1616110-replaceable-tip-drill-36-53-37-51mm","provider":"Voomi Supply","version":"1.0","type":"link"}
