It features a 1\/2 inch cutting diameter, a 140-degree split-point tip for accurate entry and reduced thrust, and an AlCrN coating that extends tool life in abrasive and heat-generating cuts. The straight-cylindrical shank measures 14.00 mm (0.5512 inches) in diameter and seats securely in standard drill chucks and toolholders. With a 2-flute spiral geometry and 5xD flute-to-diameter ratio, this bit clears chips efficiently and maintains rigidity through the cut. It is installed and operated by machinists, tool-and-die professionals, and precision fabricators.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for production and job-shop drilling in steel, stainless steel, cast iron, and other hard materials classified under ISO material groups P, M, K, and H. The SD1105A series is suited for CNC machining centers and manual drill press operations where consistent hole geometry and tight diameter tolerances are required. The m7 diameter tolerance on the cutting end supports accurate hole sizing without reaming in many applications. It is appropriate for through-hole and blind-hole drilling at depths up to 3-1\/32 inches (77.00 mm) of flute engagement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eAlCrN coating provides thermal and oxidation resistance, extending tool life in dry and semi-dry cutting\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces thrust and improves self-centering on entry\u003c\/li\u003e\n  \u003cli\u003e2-flute spiral geometry with 5xD ratio promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard ER collets and drill chucks\u003c\/li\u003e\n  \u003cli\u003em7 diameter tolerance supports accurate hole sizing in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design — suitable for external coolant or dry cutting setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the SECO SD1105A series, rated for drilling steel, stainless steel, cast iron, and hard materials (ISO groups P, M, K, H). Compatible with any machine spindle or toolholder accepting a 14.00 mm straight-cylindrical shank. Drill bit size range for this series is 0.5000 to 0.6500 decimal inch.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or toolroom technician. Secure the shank fully in the collet or chuck to the recommended grip depth before starting the spindle. Confirm the machine is powered off and the spindle is locked before changing or inspecting the bit. Do not use this bit in hand-held portable drills; it is intended for rigid machine-tool setups where runout is controlled.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.8819 inches (124.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.0315 inches (77.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3.0315 inches (60.00 mm flute engagement)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5512 inches (14.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.7717 inches (45.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlCrN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: m7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SD1105A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.38 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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 02897950\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559455260978,"sku":"02897950","price":402.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2bb7214fb9bce374e6a3ada280df9541_cd21e5bd-4ed7-4a47-b63d-e26ce843e212.jpg?v=1786432922","url":"https:\/\/voomisupply.com\/products\/seco-02897950-carbide-jobber-drill-bit-1-2-inch-sd1105a","provider":"Voomi Supply","version":"1.0","type":"link"}
