Built to Series A6181TFT specifications, it features a 150-degree Form V+A drill point and a web-thinned, tapered web configuration that reduces entry force and improves chip evacuation. At 0.4375 inches (7\/16 inch) in diameter with a 2-ply right-hand spiral flute, this bit delivers consistent, accurate holes in tough materials. Coolant-through capability makes it well-suited for sustained production drilling where heat management is critical. Licensed machinists, tool-and-die professionals, and CNC operators are the primary users.\u003c\/p\u003e\u003cp\u003eThis drill bit is rated for universal tool performance across a broad range of primary workpiece materials including cast iron, hard materials, non-ferrous metals, stainless steel, and steel. Its screw machine (stub) length format gives it added rigidity compared to jobber-length bits, making it ideal for close-tolerance drilling on machining centers, CNC lathes, and drill presses where reduced overhang and vibration control matter. The straight-cylindrical shank conforms to DIN 6535HA specification and fits standard toolholders and chucks sized for 12 mm shank diameters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction (grade K30F) for wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e150-degree Form V+A drill point with web thinning for low thrust and self-centering entry\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal coolant delivery for heat control in deep or high-speed drilling\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute geometry promotes efficient chip evacuation across workpiece material types\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank to DIN 6535HA for reliable gripping in standard toolholders\u003c\/li\u003e\n\u003cli\u003eMeets DIN and ISO standards; rated for universal tool performance across multiple material families\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for Series A6181TFT screw machine length drill bits with a 0.4375 inch diameter and a 12 mm straight-cylindrical shank conforming to DIN 6535HA.

Always power down and lock out the machine before inserting or removing the bit from the toolholder or chuck. Carbide is brittle — avoid lateral impact or side-loading during handling and setup. Verify that coolant-through supply lines are properly connected before running the spindle when using internal coolant delivery.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.4375 inches (7\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.6457 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.1654 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.7717 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12 mm straight-cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.2205 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 150 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Type\u003c\/strong\u003e: Form V+A\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 (Regular)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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 (K30F)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\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\u003eSeries\u003c\/strong\u003e: A6181TFT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: p7\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Hard Material, Non-Ferrous Metal, Stainless Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.34 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5293782\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51737016271154,"sku":"5293782","price":427.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/268aa8e378f07afa99b0e0570d646ece_6b8876c2-bf9a-4444-a3fd-b4cf52e79a37.jpg?v=1788783203","url":"https:\/\/voomisupply.com\/products\/walter-titex-5293782-solid-carbide-screw-machine-drill-bit-7-16","provider":"Voomi Supply","version":"1.0","type":"link"}
