Built from micrograin solid carbide, it delivers the hardness and edge retention needed for drilling ferrous and non-ferrous metals, cast iron, and hard plastics. The 118-degree four-facet point provides self-centering entry and reduced thrust compared to a standard chisel point. A bright, uncoated finish keeps the bit versatile across general-purpose drilling operations. With a regular spiral flute and web-thinned design, chip evacuation stays consistent through the cut.\u003c\/p\u003e\u003cp\u003eThis bit suits general-purpose drilling in machine shops, tool rooms, and fabrication environments. The straight cylindrical shank seats in standard drill chucks on CNC machining centers, manual mills, and drill presses. Right-hand cutting direction and a 2-inch flute length make it practical for through-holes and blind holes in medium-thickness stock. The 5xD flute-to-diameter ratio supports controlled chip flow in typical production setups. It is sold individually and fits workflows where a single replacement bit is needed without ordering in bulk.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for hardness and wear resistance in metalworking applications\u003c\/li\u003e\n\u003cli\u003e118-degree four-facet point with web thinning for self-centering entry and reduced drilling thrust\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with 2-inch flute length for consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for general-purpose drilling across a range of materials\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard drill chucks\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 338 standard for jobber-length drill geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit for use in standard drill chucks on CNC machining centers, manual mills, and drill presses that accept straight cylindrical shanks.

Solid carbide bits are brittle compared to high-speed steel — avoid side loading, interrupted cuts at high feed rates, or using the bit as a reamer. Ensure the workpiece is properly fixtured to prevent movement during the cut. Follow shop safety procedures and applicable OSHA standards for machine guarding when operating drill presses or machining centers.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.257 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 6.53 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Four Facet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.257 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.6094 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 101\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\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: 51206\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51729377984818,"sku":"51206","price":98.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/254b48365bbb49705e35c34e31386581.jpg?v=1788703860","url":"https:\/\/voomisupply.com\/products\/sgs-51206-jobber-drill-bit-letter-f-0-257-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
