Built from high speed steel with a TiN (titanium nitride) tip coating, the bit delivers improved wear resistance and extended cutting life compared to uncoated HSS tooling. The 118-degree split-point tip starts on contact without a center punch and reduces walking on smooth surfaces. With an overall length of 4.0000 inches and a 2.7500-inch spiral flute, this bit is suited for production and maintenance drilling in shop and field environments. It is installed and used by machinists, pipefitters, electricians, and general trade technicians.\u003c\/p\u003e\u003cp\u003eThe C97313 is intended for right-hand, spiral-flute drilling applications where a straight-cylindrical shank is required. The 1\/4-inch shank diameter fits standard three-jaw drill chucks and quick-change chuck systems found on hand drills, drill presses, and magnetic base drills. A flute-to-diameter ratio of 3xD and a tapered web configuration support chip evacuation in shallow to moderate-depth holes. The bit is rated for a maximum drilling depth of 0.6300 inches per pass in its intended application range. This series is sold individually per package with a minimum order quantity of 12 units, making it practical for stocking tool cribs and service vehicles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter E size (0.2500 inches decimal, 1\/4 inches fractional) with tight diameter tolerance of +0.0000 to -0.0007 inches per ASME B94.11M\u003c\/li\u003e\n\u003cli\u003eTiN tip coating increases surface hardness and reduces friction at the cutting edge for longer tool life\u003c\/li\u003e\n\u003cli\u003e118-degree split-point tip for self-starting cuts and reduced thrust on entry\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with tapered web promotes reliable chip evacuation in through and blind holes\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 1\/4-inch shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eMeets ASME B94.11M and ANSI specification designation for dimensional consistency\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 any drill press, hand drill, or similar rotary tool equipped with a chuck that accepts a 0.2500-inch straight-cylindrical shank.

Ensure the chuck is fully tightened around the shank before operating the drill. Secure the workpiece with a clamp or vise before starting a cut. Never exceed the rated drilling depth per pass, and back the bit out periodically on deeper holes to clear chips and prevent heat buildup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: E\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: TiN (Tip)\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: Split\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.7500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches (1\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.6300 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0007 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1500-TT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B94.11M, ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: CLE-LINE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C97313\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLE-LINE","offers":[{"title":"Default Title","offer_id":52083371835698,"sku":"C97313","price":54.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6b0fb5b935b85ffe2bdebab8e2c16d1b_afbcab8f-e95b-47a4-8d34-f8bb2b2d2c55.jpg?v=1790057479","url":"https:\/\/voomisupply.com\/products\/cle-line-c97313-jobber-drill-bit-letter-e-1-4-in-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
