At 6.5 mm (0.2559 inches) in diameter with a 135-degree split-point geometry, it delivers fast penetration and accurate starts without a center punch. The bright, uncoated finish is standard for carbide tooling used in controlled-speed applications. With an overall length of 2.5 inches and a flute length of 1.375 inches, this stub-length bit provides rigidity and reduced deflection compared to jobber-length alternatives. It is suited for machinists, tool-and-die shops, and fabrication trades working with hard and abrasive workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for use on cast iron, nickel alloy, stainless steel, titanium alloy, and tool steel. The slow spiral flute geometry controls chip evacuation in these tough materials, reducing heat buildup and extending tool life. It is commonly used in drill press, CNC machining center, and manual milling machine setups where short tool projection and high rigidity are required. A straight cylindrical shank allows direct chucking in standard drill chucks or collet holders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for use in hard and abrasive workpiece materials including stainless steel and titanium alloy\u003c\/li\u003e\n  \u003cli\u003e135-degree drill point angle reduces thrust force and improves self-centering on entry\u003c\/li\u003e\n  \u003cli\u003eSlow spiral flute design controls chip flow in gummy and stringy alloys\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish maintains tight diameter tolerances right off the grind\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length provides maximum rigidity and minimizes deflection in short-projection setups\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, straight cylindrical shank fits standard drill chucks and collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in drill presses, CNC machining centers, and manual machine tool setups that accept a straight cylindrical shank drill bit in the 6.5 mm diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and remove this bit only with the machine spindle at a full stop and with the power source locked out. Secure the shank fully in the chuck or collet to the recommended grip depth before tightening. Solid carbide tooling is brittle and sensitive to side loading — avoid using a worn or eccentric chuck that can introduce runout. Follow the cutting speed and feed rate recommendations for the specific workpiece material being drilled.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.5 mm (0.2559 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Slow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Nickel Alloy, Stainless Steel, Titanium Alloy, Tool Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 16705188\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730428002610,"sku":"16705188","price":60.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6d464b42b870119cf4e4506a0ce32ba7.jpg?v=1788717267","url":"https:\/\/voomisupply.com\/products\/hertel-16705188-screw-machine-drill-bit-6-5-mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
