Built from solid carbide with a TiNAl (titanium aluminum nitride) tip coating, this bit delivers superior hardness and heat resistance at the cutting edge. It features a 140-degree split point, a straight-cylindrical shank measuring 8 millimeters in diameter, and an overall length of 79 millimeters (3.11 inches). The two-flute right-hand cut geometry and coolant-through design make it suitable for production drilling where tool life and hole quality matter. Machinists, tool and die technicians, and CNC operators are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for use on cast iron, hard materials, non-ferrous metals, and steel. The screw machine length (stub) format provides added rigidity compared to jobber-length bits, making it well suited for short-hole drilling in machining centers, drill presses, and manual or CNC lathes. The 3xD flute-to-diameter ratio supports chip evacuation in interrupted or continuous cuts. The Series DC150-03-A1 designation places this bit within WALTER-TITEX universal performance tooling, appropriate for general-purpose and precision production work across a range of workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with TiNAl tip coating for extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle reduces thrust force and improves self-centering on entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports internal coolant delivery for deep or high-speed drilling operations\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank (8 mm diameter) compatible with standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, two-flute geometry promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMeets DIN and ISO dimensional standards for consistent fitment and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in drill presses, machining centers, and CNC equipment accepting an 8 mm straight-cylindrical shank. Primary workpiece materials include cast iron, hard materials, non-ferrous metals, and steel. Fits within the DC150-03-A1 series, covering the 6.50 mm to 8.00 mm diameter range per the series specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or CNC technicians familiar with cutting tool setup and speeds-and-feeds selection. Confirm the spindle and chuck are fully stopped and de-energized before inserting or changing the bit. Verify shank seating depth and runout with appropriate gauging before beginning a cut. When using the coolant-through feature, ensure the machine coolant system is properly pressurized and connected per the equipment manufacturer's guidelines.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.8 mm (0.2677 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Coating\u003c\/strong\u003e: TiNAl\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 79 mm (3.11 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 34 mm (1.339 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 24 mm (0.945 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8 mm (0.315 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36 mm (1.42 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.24 mm (0.049 inches)\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\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Hard Material, Non-Ferrous Metal, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.095 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: 6968781\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51728459366706,"sku":"6968781","price":103.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9c421e884831b1dd1234335822842515_60142fe2-586e-469e-9973-e22178b302f2.jpg?v=1788691539","url":"https:\/\/voomisupply.com\/products\/walter-titex-6968781-screw-machine-drill-bit-6-8mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
