Built on the Series 1501-TT platform, it features a 135-degree split point that self-centers on contact, reducing walking and allowing faster penetration without a center punch. The titanium nitride (TiN) coating reduces friction and extends tool life compared to uncoated high-speed steel. A two-flute spiral configuration with a tapered, web-thinned design improves chip evacuation and maintains cutting efficiency through deeper passes. At 6 inches overall length with a 4.5-inch flute length, it fits standard drill chucks and magnetic-base units used across metalworking and mechanical trades.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling alloy steel, carbon steel, cast iron, aluminum, and other non-ferrous metals in fabrication, maintenance, and field service applications. The straight cylindrical shank with a 0.5 inch diameter seats securely in any 1\/2 inch or larger keyed or keyless chuck. It follows ANSI specification standards and is a right-hand cutting tool, appropriate for standard drill motor operation. No coolant-through capability is required; conventional cutting fluid applied externally is compatible with this geometry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point for self-centering and reduced thrust force\u003c\/li\u003e\n\u003cli\u003eCobalt construction with TiN coating for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web design improves chip flow on deep cuts\u003c\/li\u003e\n\u003cli\u003eTwo-flute spiral geometry for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard 1\/2 inch chucks\u003c\/li\u003e\n\u003cli\u003eANSI specification compliant, right-hand cutting direction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard drill presses, handheld drills, and magnetic-base drills accepting a 1\/2 inch straight shank.

Secure the shank fully in the chuck and verify runout before drilling. Apply appropriate cutting fluid externally when drilling ferrous materials to manage heat buildup. Do not exceed the drill motor rated speed or torque capacity for the shank size.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split Point\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\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\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches (12.7 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Alloy Steel, Carbon Steel, Cast Iron, Aluminum, Non-Ferrous Metal\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: 1501-TT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.26 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: C66029\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLE-LINE","offers":[{"title":"Default Title","offer_id":51979095277874,"sku":"C66029","price":30.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7f39e51de1c6a1a60d2c2c649f1c53fe_ba3fe183-b63d-4749-a289-992f6c49d4cc.jpg?v=1789980615","url":"https:\/\/voomisupply.com\/products\/cle-line-c66029-cobalt-jobber-drill-1-2-in-tin-split-point","provider":"Voomi Supply","version":"1.0","type":"link"}
