Built on the DC150-12-A1 series platform, it features a 9.8 mm cutting diameter, a 140-degree point angle, and a TiNAl coating that provides heat resistance and extended tool life in high-temperature cutting environments. The straight-cylindrical shank measures 10.00 mm in diameter and 40.00 mm in length, fitting standard collet and chuck systems. With a flute length of 138 mm and an overall length of 180 mm, this bit reaches deep into workpieces where standard-length tooling cannot. It is sized to the m7 diameter tolerance class and is installed by machinists and tooling professionals in CNC and manual drilling operations.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is engineered for production and job-shop environments where difficult alloys and non-standard entry geometries are common. Primary workpiece materials include cobalt, iron, nickel, and titanium alloys. Secondary workpiece materials include glass and graphite. Its geometry supports blind hole drilling, cross hole drilling, inclined hole exits, and stack drilling applications, making it a versatile choice for aerospace, medical, and heavy industrial machining operations where material removal rates and hole quality are critical.\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-alloy machining\u003c\/li\u003e\n  \u003cli\u003eTiNAl coating reduces heat buildup and extends tool life in titanium and nickel alloys\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle optimizes chip formation and reduces thrust force at entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design delivers cutting fluid directly to the cutting edge for deep-hole applications\u003c\/li\u003e\n  \u003cli\u003e12xD flute-to-diameter ratio with 138 mm flute length supports maximum drilling depth of 123 mm\u003c\/li\u003e\n  \u003cli\u003eSuitable for blind holes, cross holes, inclined hole exits, and stack drilling\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI, DIN 6535 HA, and ISO standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and drilling machines equipped with collet or chuck systems accepting a 10.00 mm straight-cylindrical shank.

Verify collet or chuck runout before seating the shank to maintain hole diameter tolerance at m7. Do not exceed the maximum drilling depth of 123 mm. When drilling titanium or nickel alloys, confirm coolant-through flow is active before initiating the cut to prevent premature edge wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9.8 mm (0.3858 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: 180 mm (7.087 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 138 mm (5.433 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 123 mm (4.843 inches)\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: 10.00 mm (0.394 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 40.00 mm (1.575 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.78 mm (0.070 inches)\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: 12xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiNAl\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: m7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cobalt, Iron, Nickel, Titanium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Glass, Graphite\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DC150-12-A1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, DIN 6535 HA, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 7.28 inches L x 0.67 inches W x 0.67 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.029 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: 6618826\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51739544748338,"sku":"6618826","price":278.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/75bc2c83fd150f2b37ea4dd0fbe3020f_a38c07eb-2810-4858-a9c2-31d69e0016c1.jpg?v=1788816057","url":"https:\/\/voomisupply.com\/products\/walter-titex-6618826-extra-length-drill-bit-9-8-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
