Built from solid carbide with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction in tough workpiece materials. The bit measures 1-13\/16 inches overall length with a 13\/16-inch flute length and a 7\/64-inch (0.1094 inch) diameter. The 135-degree split point and web-thinned geometry reduce thrust force and improve centering without a pilot hole. With a maximum drilling depth of 1.77 inches, this bit suits precision hole-making in short-reach applications where rigidity and accuracy are critical.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is engineered for use in cast iron, nickel alloys, stainless steel, titanium alloys, and tool steel — materials that demand carbide construction and a geometry that resists work hardening and galling. The screw machine length (stub length) profile provides added rigidity compared to jobber-length bits, making it well-suited for CNC machining centers, turret lathes, drill presses, and manual screw machines where short reach and minimal deflection matter. Machinists, tool and die makers, and production shop technicians are the primary users of this type of bit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction rated to material grade C2 for hardness and wear resistance in ferrous and exotic alloys\u003c\/li\u003e\n  \u003cli\u003eTiN (titanium nitride) coating reduces friction, improves surface hardness, and extends cutting life\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning reduces entry thrust and improves self-centering\u003c\/li\u003e\n  \u003cli\u003eSlow spiral flute geometry suited to hard, short-chip materials such as cast iron and stainless steel\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.0000 to -0.0005 inches ensures close-tolerance hole production\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the HERTEL HSSC135-TN-SS series.

Power down and de-energize the machine spindle before changing tooling. Use appropriate cutting fluid or coolant compatible with the workpiece material even though this bit does not feature through-coolant capability. Follow the machine manufacturer and shop safety guidelines for RPM and feed rate selection when working with carbide tooling in hard or exotic alloys.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7\/64 inch (0.1094 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 13\/16 inch (0.8125 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.77 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split Point\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: C2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute\/Spiral Type\u003c\/strong\u003e: Slow Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: +0.0000 to -0.0005 inches\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\u003eSeries\u003c\/strong\u003e: HSSC135-TN-SS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 16691933\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727221129522,"sku":"16691933","price":18.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/47560edf2daf91708bccbf05fa53c4c9.jpg?v=1788674909","url":"https:\/\/voomisupply.com\/products\/hertel-16691933-screw-machine-drill-bit-7-64-inch-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
