Measuring 0.2835 inches (7.20 mm) in diameter with an overall length of 3.11 inches, this bit features a 140-degree drill point angle suited for self-centering entry into hard and abrasive workpiece materials. The TiNAl coating improves heat resistance and extends tool life in high-speed applications. A through-coolant design allows internal coolant delivery directly to the cutting edge, reducing heat buildup and chip evacuation problems during deep-hole operations. This bit is installed by machinists, tool-and-die professionals, and production drilling technicians.\u003c\/p\u003e\n\u003cp\u003eThe 6968786 is built for universal tool performance across a range of workpiece materials including cast iron, hard materials, non-ferrous metals, and steel. The screw machine length geometry  -  shorter than jobber length  -  provides added rigidity in CNC machining centers, drill presses, and automated production setups where runout and deflection must be minimized. The straight-cylindrical shank at 0.3150 inches (8.00 mm) fits standard drill chucks and collet holders without modification. The Series DC150-03-A1 designation identifies this as part of a coordinated family of solid carbide drills conforming to DIN and ISO standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eTiNAl coating provides thermal barrier and extends cutting life in high-speed drilling\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design delivers coolant directly to the drill tip for heat control and chip flushing\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle enables self-centering entry and reduced thrust in production drilling\u003c\/li\u003e\n  \u003cli\u003e2-flute geometry with a 3xD flute-to-diameter ratio supports efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN and ISO standards for dimensional consistency and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the DC150-03-A1 series, this drill bit is designed for use in CNC machining centers, drill presses, and production drilling equipment accepting a 0.3150-inch straight-cylindrical shank. Rated for cast iron, hard materials, non-ferrous metals, and steel workpieces. Drill bit size falls within the 0.2500 to 0.3000 inch (6.50 to 8.00 mm) size range of this series.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by qualified machinists or tooling technicians familiar with carbide tooling requirements. Ensure the spindle and chuck or collet system is fully de-energized and at rest before tool changes. Carbide tooling is brittle  -  avoid side-loading, impact contact with hard surfaces, or use in applications with interrupted cuts unless the tool is specifically rated for them. Verify coolant-through compatibility with the machine spindle before engaging internal coolant flow.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2835 inches (7.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.11 inches (79.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.614 inches (41.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3150 inches (8.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.42 inches (36.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.142 inches (29.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.052 inches (1.31 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiNAl\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Hard Material, Non-Ferrous Metal, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: m7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DC150-03-A1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.099 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WALTER-TITEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6968786\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51739799585074,"sku":"6968786","price":131.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9c421e884831b1dd1234335822842515_9e9299e6-5640-43ad-9e76-275c2dbd6fc1.jpg?v=1788818992","url":"https:\/\/voomisupply.com\/products\/walter-titex-6968786-screw-machine-drill-bit-0-2835in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
