Built to DIN 1897 standards, this 0.5709-inch (14.50 mm) diameter bit features a parabolic flute geometry and a 130-degree split point for aggressive chip evacuation and reduced walking on entry. The straight-cylindrical shank seats securely in standard drill chucks and CNC toolholders. At 4.37 inches overall length with a 2.2047-inch flute length, it fits compact setups where standard-length bits are too long. Heavy-duty cobalt construction handles the heat and hardness associated with aerospace-grade and high-strength alloy materials. Licensed machinists, tool-and-die technicians, and manufacturing floor operators are the primary users.\u003c\/p\u003e\u003cp\u003eThis stub-length drill bit is suited for production machining, job shop work, and maintenance applications where titanium alloy, stainless steel, and other hard metals are common. The shorter overall length improves rigidity and reduces deflection in high-feed drilling scenarios. The parabolic flute profile moves chips out of the hole efficiently, which is critical when drilling sticky or stringy alloys that load up conventional flute geometries. Maximum drilling depth is 1.348 inches (34.25 mm), making this appropriate for through-holes and moderate-depth blind holes in workpieces up to that depth.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e14.50 mm (0.5709 inches) diameter with a tolerance of +0.000 to -0.027 mm for controlled fit\u003c\/li\u003e\n\u003cli\u003e130-degree standard point angle with web thinning for reduced thrust and cleaner entry\u003c\/li\u003e\n\u003cli\u003eParabolic flute design promotes efficient chip removal in titanium and hard alloys\u003c\/li\u003e\n\u003cli\u003eCobalt tool material resists heat buildup during high-speed or dry cutting operations\u003c\/li\u003e\n\u003cli\u003eStub (screw machine) length improves rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 1897 specification for consistent dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 1897 stub-length drill bit for use in drill presses, CNC machining centers, and manual machine tools equipped with standard straight-shank toolholding.

Secure the shank fully in the chuck or collet and verify runout before beginning a cut. Ensure the machine is at a full stop before changing or inspecting the bit. Follow shop-specific feeds and speeds for cobalt tooling in titanium alloy, and verify workpiece clamping is adequate before drilling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.5709 inches (14.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.37 inches (111.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.2047 inches (56.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.348 inches (34.25 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\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: Parabolic\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: Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub (Screw Machine)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.027 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1897\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 659\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.27 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: GUHRING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9006590145000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51739663728946,"sku":"9006590145000","price":150.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b4840e98f8ad2689b548445c81989ae9.jpg?v=1788817486","url":"https:\/\/voomisupply.com\/products\/guhring-9006590145000-cobalt-stub-drill-bit-0-5709-in","provider":"Voomi Supply","version":"1.0","type":"link"}
