Built from solid carbide with a bright uncoated finish, this bit measures 7\/64 inch (0.1094 inches) in diameter and features a 135-degree split point for fast, accurate starts with minimal walking. The slow spiral flute design and web-thinned parallel web configuration are engineered specifically for drilling cast iron, nickel alloys, stainless steel, titanium alloys, and tool steel. Right-hand cut with a straight cylindrical shank, this bit is a standard choice for machinists and toolroom professionals working on precision production applications.\u003c\/p\u003e\u003cp\u003eScrew machine length drill bits are shorter and more rigid than jobber-length bits, making them well suited for CNC machining centers, turret lathes, screw machines, and drill presses where stub-length rigidity reduces deflection and improves hole accuracy. This bit is appropriate for shops drilling hard ferrous and exotic alloy workpieces where a standard high-speed steel bit would wear prematurely. The solid carbide construction maintains cutting performance at elevated spindle speeds common in production environments. Overall length is 1-3\/16 inches with a flute length of 13\/16 inch.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for extended tool life in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces thrust and eliminates center-punch requirement\u003c\/li\u003e\n\u003cli\u003eSlow spiral flute promotes chip evacuation in cast iron, stainless steel, and titanium alloys\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web lowers cutting resistance and reduces heat buildup\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks and collets without modification\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.0000 to -0.0005 inches for close-tolerance hole requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw machine length replacement bit for applications involving cast iron, nickel alloy, stainless steel, titanium alloy, and tool steel workpieces.

Carbide is brittle compared to high-speed steel  -  avoid lateral loading, interrupted cuts without appropriate feeds, and dropping the bit on hard surfaces. Secure the straight shank firmly in a collet or drill chuck to the manufacturer-specified runout tolerance before engaging the workpiece. Coolant-through capability is not available on this bit, so external coolant or cutting fluid application is recommended when drilling stainless steel or titanium alloys to manage heat.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7\/64 inch (0.1094 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eSpiral Type\u003c\/strong\u003e: Slow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 13\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel Web-Thinned\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\u003eMaterial Grade\u003c\/strong\u003e: C2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 74148776\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51744446153010,"sku":"74148776","price":17.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/606159f2b875c83ad930ec977de609be.jpg?v=1788856630","url":"https:\/\/voomisupply.com\/products\/hertel-74148776-screw-machine-drill-bit-7-64-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
