Built from high speed steel with a titanium nitride tip coating, this bit delivers extended cutting life at the point where wear is greatest. The 3\/8 inch diameter, 118-degree split point, and regular spiral geometry make it a reliable choice for everyday production drilling. At 5 inches overall length with a 3.63-inch flute, it fits standard drill chucks and drill press setups without modification. Machinists, pipefitters, electricians, and general trade mechanics commonly keep this size stocked for field and shop use.\u003c\/p\u003e\u003cp\u003eThis bit suits residential and light commercial applications where a 3\/8 inch hole is required in ferrous and non-ferrous stock. The straight cylindrical shank fits standard 3-jaw chucks on corded drills, cordless drills, and drill presses. The 1500-TT series designation indicates high-performance tooling with tip-only TiN coating, which reduces heat buildup at the cutting edge during repetitive drilling cycles. Maximum recommended drilling depth is 0.94 inches per pass, consistent with the 3xD flute-to-diameter ratio of jobber-length geometry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8 inch diameter with tight tolerance of +0.0000 to -0.0010 inches for consistent hole sizing\u003c\/li\u003e\n\u003cli\u003e118-degree split point reduces walking and lowers thrust required to start the cut\u003c\/li\u003e\n\u003cli\u003eTiN tip coating extends cutting-edge life compared to uncoated HSS\u003c\/li\u003e\n\u003cli\u003eRegular spiral, 2-flute design promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eTapered web configuration adds rigidity across the full flute length\u003c\/li\u003e\n\u003cli\u003eMeets ASME B94.11M standard for jobber-length drill bits\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with any 3-jaw chuck accepting a 3\/8 inch straight cylindrical shank, including standard corded and cordless drills and benchtop drill presses.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the shank fully in the chuck and verify chuck key is removed before starting the spindle. Use cutting fluid or coolant when drilling ferrous materials to extend bit life and manage heat. Always clamp the workpiece before drilling to prevent rotation. Inspect the tip coating and cutting edges before each use and replace the bit if chipping or excessive wear is present.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3\/8 inch (0.3800 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.63 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3800 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.94 inches\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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 inches\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 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: C97321\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLE-LINE","offers":[{"title":"Default Title","offer_id":51996082700594,"sku":"C97321","price":57.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6b0fb5b935b85ffe2bdebab8e2c16d1b_8f0e1ee7-c851-4509-83a9-eb50d4469383.jpg?v=1789993150","url":"https:\/\/voomisupply.com\/products\/cle-line-c97321-3-8-inch-hss-tin-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
