It features a 5\/16-inch (0.3125 inch) cutting diameter, a 140-degree standard point angle, and an AlCrN coating that extends tool life when cutting abrasion-resistant and hard materials. The spiral flute design promotes efficient chip evacuation, and the straight-cylindrical shank with an 8 mm (0.315 inch) diameter seats securely in standard drill chucks and toolholders. Overall length is 91 mm (3.58 inches). This bit is intended for right-hand, clockwise cutting and is part of the SECO SD1105A series. Machinists and CNC operators in metalworking shops are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for use in steel, stainless steel, cast iron, and hard materials, corresponding to ISO workpiece material codes P, M, K, and H. The 7xD flute-to-diameter ratio and 53 mm (2.09 inch) flute length support deep-hole entry relative to diameter within the jobber-length class. The maximum drilling depth is 43 mm (2.09 inches). It carries no coolant-through capability, making it suited for dry or flood-coolant external delivery setups. This is a general-purpose, high-performance bit appropriate for drilling operations on both CNC machining centers and conventional drill presses where carbide tooling is specified.\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 materials\u003c\/li\u003e\n  \u003cli\u003eAlCrN coating provides oxidation resistance and extended tool life in steel and stainless steel applications\u003c\/li\u003e\n  \u003cli\u003e140-degree standard point angle reduces thrust and improves centering on entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute geometry promotes consistent chip evacuation during through-hole and blind-hole drilling\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eANSI-specification compliance ensures dimensional conformance for toolholder fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a high-performance OEM-style solid carbide jobber drill for use in standard drill chucks and collet-style toolholders accepting a 0.315-inch straight-cylindrical shank, conforming to ANSI specifications for jobber-length drill bits in the 0.3000 to 0.3500 inch diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this drill bit is performed by qualified machinists or CNC operators. Secure the straight-cylindrical shank fully and evenly in the chuck or collet before operation to prevent runout and premature tool failure. Ensure the spindle and workpiece are properly fixtured and that all guards are in place before initiating a cut. This bit does not support coolant-through delivery; apply external coolant or cutting fluid at the tool-workpiece interface as required by the material and cut parameters.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\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\u003eOverall Length\u003c\/strong\u003e: 91 mm (3.58 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 53 mm (2.09 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 43 mm (2.09 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8 mm (0.315 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36 mm (1.42 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 7xD\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: m7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Hard Material (ISO codes P, M, K, H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SD1105A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.57 x 0.59 x 0.51 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 02897912\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563294523698,"sku":"02897912","price":173.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2bb7214fb9bce374e6a3ada280df9541_600640a0-e1e8-4bf0-b3b4-5c0063433be7.jpg?v=1786494885","url":"https:\/\/voomisupply.com\/products\/seco-02897912-jobber-drill-bit-5-16-in-solid-carbide-140-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
