It measures 6.1 mm in diameter with a 140-degree drill point and carries a TiSiAlCrN coating for heat and wear resistance. The flute length runs 228 mm with an overall length of 268 mm, giving it a 30xD flute-to-diameter ratio that supports deep-hole applications. The straight-cylindrical shank measures 8 mm in diameter with a 36 mm shank length. Two right-hand flutes and coolant-through capability make this bit suited to production environments where chip evacuation and thermal management are critical. A licensed machinist or toolroom technician is the typical end user.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for blind hole, cross hole, inclined hole exit, and stack drilling operations. Primary workpiece materials include alloy steel and titanium alloy, with secondary suitability for glass and graphite. The 30xD depth capacity and TiSiAlCrN coating make it a practical choice for aerospace, medical device, and precision machining applications where extended reach and tight tolerances are required. The h7 diameter tolerance on the 6.1 mm cutting diameter supports close-fit bore work without secondary reaming in many applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with TiSiAlCrN 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 centering on entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip evacuation and heat control in deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003e30xD flute-to-diameter ratio enables maximum drilling depth of 217 mm\u003c\/li\u003e\n  \u003cli\u003eh7 diameter tolerance on the 6.1 mm cutting edge for precision bore applications\u003c\/li\u003e\n  \u003cli\u003eRated for blind hole, cross hole, inclined hole exit, and stack drilling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and drill presses accepting a straight-cylindrical 8 mm shank.

Part of the WALTER-TITEX DC160-30-A1 series.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or toolroom technician. Verify that the machine spindle and collet or chuck are clean and within tolerance for an 8 mm straight-cylindrical shank before seating the bit. Power down and lock out the machine before changing tooling. Coolant-through channels require a compatible spindle coolant delivery system to function as designed; confirm coolant pressure and flow rate match machine specifications before running production cycles.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.1 mm (0.2402 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\u003eOverall Length\u003c\/strong\u003e: 268 mm (10.551 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 228 mm (8.976 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 217 mm (8.543 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 (1.417 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.11 mm (0.044 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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 30xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: h7\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: TiSiAlCrN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DC160-30-A1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 14.21 inches long x 0.67 inches wide x 0.67 inches high\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.168 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: 7684387\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51754814538034,"sku":"7684387","price":1144.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/de55c6c0b03185842e31400ac1f511d3_806c50fb-a38e-4499-8617-673f008d2034.jpg?v=1788948824","url":"https:\/\/voomisupply.com\/products\/walter-titex-7684387-extra-length-drill-bit-6-1-mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
