It measures 0.3438 inches (11\/32 inch) in diameter and features a 150-degree Form V+A drill point, which reduces thrust and improves centering in hard and abrasive workpieces. The straight-cylindrical shank follows DIN 6535HA specification, and the bit runs coolant-through for effective chip evacuation and heat control. At 4.0551 inches overall length with a 1.8504-inch spiral flute, this bit is built for CNC machining centers and drill presses where compact length and rigidity matter. Series A6181TFT construction targets universal tool performance across a range of ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for production machining environments including aerospace, automotive, and general metalworking shops. It handles cast iron, hard materials, non-ferrous metals, stainless steel, and steel. The screw machine length profile provides added stiffness compared to jobber-length bits, making it a reliable choice for tightly toleranced through-holes and blind holes where deflection must be minimized. The 3xD flute-to-diameter ratio and web-thinned tapered web design support efficient chip flow at typical CNC feed and speed conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with coated finish for wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design aids chip evacuation and extends tool life in deep-hole applications\u003c\/li\u003e\n  \u003cli\u003e150-degree Form V+A point reduces entry thrust and improves self-centering\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers cutting forces and supports smooth chip flow\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank per DIN 6535HA for secure collet or chuck clamping\u003c\/li\u003e\n  \u003cli\u003eTwo-flute spiral design rated for cast iron, stainless steel, steel, hard materials, and non-ferrous metals\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 equipped with collets or chucks accepting a straight-cylindrical 10 mm shank; rated for cast iron, hard materials, non-ferrous metals, stainless steel, and steel per Series A6181TFT application guidelines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and locked out before mounting or removing the bit. Verify coolant-through capability is active at the spindle before running in deep-hole applications to avoid chip packing and premature tool failure. Follow the tool manufacturer and machine builder guidelines for feed rate, spindle speed, and clamping torque appropriate to the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 11\/32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3438 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: K30F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.8504 inches (47.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 150 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Form V+A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0461 inches (1.17 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0551 inches (103.00 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: 10.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.5748 inches (40.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.0630 inches (27.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: Universal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: p7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Hard Material, Non-Ferrous Metal, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A6181TFT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Number\u003c\/strong\u003e: DIN 6535HA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 5293778\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51744675430706,"sku":"5293778","price":304.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/268aa8e378f07afa99b0e0570d646ece_2672af84-723f-4100-bb4a-40c9ead034ae.jpg?v=1788859869","url":"https:\/\/voomisupply.com\/products\/walter-titex-5293778-screw-machine-drill-bit-0-3438-in","provider":"Voomi Supply","version":"1.0","type":"link"}
