With a 0.1563-inch diameter, a 140-degree drill point angle, and a TiNAl (titanium aluminum nitride) coating, this bit delivers high thermal resistance and extended tool life in tough materials. The flute-to-diameter ratio of 12xD supports deep-hole work while the coolant-through design helps evacuate chips and manage heat during extended drilling cycles. It is sized for use in CNC machining centers and automated drilling equipment where consistent hole geometry and tight tolerances are required.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for use in cobalt, iron, nickel, and titanium alloys, as well as secondary materials including glass and graphite. Typical applications include blind hole drilling, cross hole drilling, inclined hole exits, and stack drilling. The straight-cylindrical shank with a 0.2360-inch shank diameter and a 6.00 mm shank is compatible with standard collet and chuck toolholding systems. The DC150-12-A1 series is suited for high-production environments where repeatability and close-tolerance hole quality are priorities.\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 workpiece materials\u003c\/li\u003e\n  \u003cli\u003eTiNAl coating provides high-temperature resistance and extends cutting edge life\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip evacuation and thermal management during deep drilling\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle reduces thrust force and improves centering on entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting, 2-flute geometry for efficient chip flow in through and blind holes\u003c\/li\u003e\n  \u003cli\u003eQualified to ANSI, DIN 6535 HA, and ISO standards for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC drilling and machining operations with cobalt, iron, nickel, and titanium alloy workpieces, as well as glass and graphite.

Ensure the spindle and machine are powered down and locked out before changing tooling. Verify shank seating depth and runout with a dial indicator before initiating a cut. Always confirm that coolant-through supply is connected and flowing before drilling into rated workpiece materials to prevent premature tool wear or breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1563 inches (3.97 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.016 inches (102.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.52 inches (64.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.205 inches (56.00 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\u003eDrill Point Length\u003c\/strong\u003e: 0.028 inches (0.72 mm)\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: 0.2360 inches (6.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.417 inches (36.00 mm)\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: m7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cobalt; Iron; Nickel; Titanium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Glass; Graphite\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Blind Hole; Cross Hole; Inclined Hole Exit; Stack Drilling\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: 5.43 x 0.51 x 0.47 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 6618759\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51739913945394,"sku":"6618759","price":275.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/75bc2c83fd150f2b37ea4dd0fbe3020f_12008adb-8788-4d26-9101-14db9b4fbf83.jpg?v=1788820335","url":"https:\/\/voomisupply.com\/products\/walter-titex-6618759-extra-length-carbide-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
