Part of the CROWNLOC series, it accepts tip diameters ranging from 12.5 mm to 12.99 mm (0.4921 to 0.5114 inches) and delivers a maximum drill depth of 65 mm (2.5591 inches), providing a 5xD depth-to-diameter ratio. The drill features a 5\/8 inch Weldon Flat shank for secure tool holding, a TiAlN coating for heat and wear resistance, and through-coolant capability to aid chip evacuation and extend tool life. Weighing 0.4 pounds, this tool is intended for use by machinists and CNC operators in production environments.\u003c\/p\u003e\n\u003cp\u003eThe SECO 02445836 is suited for holemaking operations on CNC machining centers and milling machines where replaceable-tip drills offer a cost-effective alternative to solid-carbide drills. The Weldon Flat shank is compatible with SD105-style toolholders, making it a practical fit for shops running standard modular tooling setups. Through-coolant delivery helps manage heat and chips in medium-to-deep hole drilling, particularly in steel and ferrous materials where TiAlN coatings perform best. This is a single-piece unit packaged individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReplaceable-tip design in the CROWNLOC series reduces tooling cost compared to solid-carbide drills\u003c\/li\u003e\n  \u003cli\u003eTip diameter range of 12.5 to 12.99 mm (0.4921 to 0.5114 inches) for flexible sizing\u003c\/li\u003e\n  \u003cli\u003e5xD depth-to-diameter ratio with 65 mm (2.5591 inches) maximum drill depth\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating provides high-temperature and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant capability supports chip evacuation and thermal management\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch Weldon Flat shank compatible with SD105-style toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with SD105-style toolholders.

Always ensure the machine spindle is fully stopped and locked out before mounting or removing the drill body or replaceable tip. Verify the Weldon Flat shank is fully seated in the toolholder and that set screws are tightened against the flat per the toolholder manufacturer specifications. Confirm coolant channels are clear and through-coolant pressure is set appropriately for the operation before running the cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CROWNLOC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Drill Diameter\u003c\/strong\u003e: 12.50 mm (0.4921 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 12.99 mm (0.5114 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 65 mm (2.5591 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: 5.567 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.89 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 3.677 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.89 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: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: SD105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Holemaking\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 9766\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291502\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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 02445836\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557662523698,"sku":"02445836","price":593.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6e044808ace7e46c4efd5637cfbe41eb.jpg?v=1786392318","url":"https:\/\/voomisupply.com\/products\/seco-02445836-replaceable-tip-drill-12-5-12-99mm-weldon","provider":"Voomi Supply","version":"1.0","type":"link"}
