With a 1\/4 inch (0.2500 inch) diameter and a 137-degree split point, this bit delivers fast penetration and accurate hole starts without center-punching. The web-thinned tip reduces thrust and improves chip evacuation. At 3.11 inches overall length, the screw machine (stub) format provides added rigidity over jobber-length bits, reducing deflection in demanding applications. Coolant-through capability makes it suitable for use in CNC machining centers and automated drilling equipment where through-spindle coolant is available. Two regular spiral flutes and a proprietary coated finish extend tool life in production environments.\u003c\/p\u003e\n\u003cp\u003eThe SGS 56410 is suited for precision drilling operations in metalworking, manufacturing, and fabrication shops. Its universal primary workpiece material rating means it can be run in steel, stainless steel, aluminum, cast iron, and similar materials, depending on feeds, speeds, and coolant strategy. The straight cylindrical shank fits standard drill chucks and collet holders. Its compact stub length makes it a preferred choice for applications requiring close-tolerance holes in tight clearance situations or on CNC machining centers where tool stick-out must be minimized.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for extended tool life and heat resistance\u003c\/li\u003e\n  \u003cli\u003e137-degree web-thinned split point for reduced thrust and self-centering entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports through-spindle coolant delivery for chip flushing and heat control\u003c\/li\u003e\n  \u003cli\u003e4-margin geometry improves hole quality and concentricity\u003c\/li\u003e\n  \u003cli\u003eProprietary coated finish for improved wear resistance and lubricity\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length provides increased rigidity and reduced deflection versus jobber-length bits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or production tooling option for standard straight-shank drill chucks and collet holders accepting a 1\/4 inch shank diameter.

Ensure the shank is fully seated and the chuck or collet is properly torqued before operation. Verify that through-spindle coolant pressure and flow rate are within the range recommended by your machine tool manufacturer before engaging coolant-through operation. Carbide tooling is brittle — avoid impact loading, side pressure, or interrupted cuts without confirming the bit is rated for that application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2500 inches (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.11 inches (78.9991 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.3386 inches (34.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4173 inches (35.999 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.315 inches (8.0010 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0518 inches (1.32 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.3386 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Micrograin Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Proprietary Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Margins\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 142P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.00024 to +0.00083 inches (+0.006 to +0.021 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: SGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 56410\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51730668650802,"sku":"56410","price":247.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/40bbeb29e008228609ffd6575f2b34e8_d6f51dfe-0bd2-4455-a564-e004e2cd6ff0.jpg?v=1788721168","url":"https:\/\/voomisupply.com\/products\/sgs-56410-screw-machine-drill-bit-1-4-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
