Built to Series 135M specifications, it features a 145-degree notched point angle and an AlTiN (Ti-NAMITE-A) coating that provides heat resistance and extended tool life in abrasive cutting conditions. The 15.50 mm (0.6102 inch) diameter, right-hand cut geometry and web-thinned tapered web reduce thrust and improve chip evacuation. This bit is installed by machinists and tooling technicians working on CNC machining centers, drill presses, and manual mills where precision hole tolerances and tool longevity are priorities.\u003c\/p\u003e\u003cp\u003eThe SGS 63203 is suited for drilling alloy steels and titanium, materials that demand a rigid, heat-resistant tool. The screw machine length format provides a shorter, stiffer profile compared to jobber-length bits, reducing deflection in close-tolerance applications. With a 3xD flute-to-diameter ratio and a maximum drilling depth of 45.00 mm, it fits production and job-shop environments where repeatable hole quality in tough workpiece materials is required. The straight shank and 16.00 mm shank diameter allow direct mounting in standard chucks and collet holders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eAlTiN (Ti-NAMITE-A) coating for elevated heat resistance and reduced tool wear in titanium and alloy steel\u003c\/li\u003e\n\u003cli\u003e145-degree notched point angle reduces cutting force and improves self-centering\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web lowers thrust requirements and aids chip removal\u003c\/li\u003e\n\u003cli\u003eScrew machine length (short series) profile minimizes deflection in tight-tolerance drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flute geometry for consistent chip flow\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use tooling for machining centers, CNC drill presses, and manual drill presses accepting straight-shank drill bits with a 16.00 mm shank diameter.

Ensure the machine spindle and chuck or collet are clean and within tolerance before seating the straight shank. Carbide is brittle — avoid side-loading or using in worn spindles with runout, as this can cause chipping or fracture. Follow the machine manufacturer and tooling guidelines for appropriate speeds and feeds for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 15.50 mm (0.6102 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN (Ti-NAMITE-A)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 145 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Notched\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 65.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 45.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 115.00 mm (4.5276 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 16.00 mm (0.6299 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 48.00 mm (1.8898 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered Web-Thinned\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 Bit Diameter Tolerance\u003c\/strong\u003e: +0.0076 to +0.0254 mm\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: 135M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Alloy Steel, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 63203\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51747715580210,"sku":"63203","price":674.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cdb049d7287df238645efca4f6bdff1_bb487eab-738b-49e3-b521-3508f1a1e1cd.jpg?v=1788884580","url":"https:\/\/voomisupply.com\/products\/sgs-63203-screw-machine-drill-bit-15-50mm-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
