Built from heavy-duty high speed steel with a black oxide finish, this bit measures 29\/64 inch (0.4531 inches) in diameter and features a 135-degree split point for self-centering starts without a center punch. The shorter screw machine length body reduces deflection and increases rigidity compared to jobber-length bits, making it well suited for close-clearance work in drill presses, CNC machines, and hand drills. Two spiral flutes evacuate chips efficiently throughout the 2.125-inch flute length.\u003c\/p\u003e\u003cp\u003eThis bit is used in general metalworking, fabrication shops, maintenance and repair operations, and light production environments. The straight-cylindrical shank provides secure clamping in standard three-jaw chucks and quick-change systems. At 0.4531 inches, the bit falls in the 0.45 to 0.50 inch size range and is commonly selected by machinists, millwrights, and HVAC or plumbing tradespeople drilling through structural steel, pipe, and sheet metal during installation or retrofit work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point for self-centering starts and reduced thrust\u003c\/li\u003e\n\u003cli\u003eHeavy-duty high speed steel construction for durability in ferrous metals\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish reduces friction and provides light corrosion resistance\u003c\/li\u003e\n\u003cli\u003eScrew machine length body increases rigidity and reduces deflection\u003c\/li\u003e\n\u003cli\u003eTwo spiral flutes for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and quick-change holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw machine length replacement bit for standard three-jaw chucks and quick-change chuck systems accepting straight-cylindrical shanks in the 29\/64 inch diameter class.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified machinists or tradespeople familiar with drilling operations. Secure the shank fully in the chuck and verify concentricity before starting the cut. Use appropriate cutting fluid for the material being drilled to extend tool life and improve hole finish. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 29\/64\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.4531 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.125 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\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\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.4500 to 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 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: TITAN USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CD30029\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51747566584114,"sku":"CD30029","price":15.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4c622e24c714780dc1a7503ed4b7fd76_7e5e6b44-41ef-4e3b-830e-70476e44a7db.jpg?v=1788882678","url":"https:\/\/voomisupply.com\/products\/titan-usa-cd30029-29-64-in-screw-machine-drill-bit-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
