It carries an AlCrN (aluminum chromium nitride) coating that improves heat resistance and extends tool life in demanding applications. The straight-cylindrical shank measures 6.00 mm in diameter and fits standard drill chucks and collet holders. At 74.00 mm overall length, this is a right-hand, two-flute spiral drill built for precision hole-making in production machining environments. It is installed and used by machinists, tool-and-die technicians, and CNC operators working in job shops or manufacturing facilities.\u003c\/p\u003e\n\u003cp\u003eThis drill is engineered for use in steel, stainless steel, cast iron, and other hard materials — workpiece material codes P, M, K, and H in ISO classification. The SD1105A series targets applications where consistent hole quality and dimensional accuracy are required. A 6xD flute-to-diameter ratio provides a maximum drilling depth of 29.00 mm. Coolant-through is not supported; external flood or mist coolant is the appropriate approach for this design.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eAlCrN coating increases surface hardness and thermal resistance at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e140-degree standard point angle reduces thrust force and improves centering on entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand, two-flute regular spiral design for efficient chip evacuation in through and blind holes\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 6.00 mm diameter for direct chuck or collet mounting\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance class m7 ensures consistent fit in precision bore applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill chucks and collet holders accepting a 6.00 mm straight-cylindrical shank. Suitable for CNC machining centers, drill presses, and manual machines where 4.20 mm diameter holes are required in steel, stainless steel, cast iron, and hard materials per ISO workpiece material codes P, M, K, and H. Conforms to ANSI standards per specification designation SD1105A.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eEnsure the machine spindle and workpiece are fully secured before tool engagement. Mount the shank in a collet or drill chuck with sufficient grip length to prevent pullout under cutting loads. Carbide drills are brittle — avoid side loading, interrupted cuts without appropriate feed reduction, and contact with hardened fixture surfaces. External coolant should be directed at the cutting zone to manage heat when drilling stainless steel or hard materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.20 mm (0.1655 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 74.00 mm (2.9156 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 36.00 mm (1.4184 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 29.00 mm (1.4184 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm (0.2364 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36.00 mm (1.4184 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: 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\u003eCoating\u003c\/strong\u003e: AlCrN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: m7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDouble Margin\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: 0.04 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: 02897862\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559810957618,"sku":"02897862","price":147.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1d7aa7e9c1723d6c8c715aa0d0f907d3_4ff7c1ec-4f18-4d6e-8fe2-5dffb6947c40.jpg?v=1786441705","url":"https:\/\/voomisupply.com\/products\/seco-02897862-solid-carbide-jobber-drill-4-20-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
