Ground from solid carbide to a C2 material grade, this bit features a 135-degree split point that reduces walking and allows drilling without a center punch. The slow spiral flute geometry controls chip evacuation and maintains edge integrity in tough workpieces. At 0.125 inches in diameter with a 1-7\/8-inch overall length, it is sized for short-reach applications where rigidity and hole quality matter. Machinists and tool room technicians rely on this bit for accurate, consistent results in production and maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is engineered for use in cast iron, nickel alloy, stainless steel, titanium alloy, and tool steel. The screw machine length format keeps overhang minimal, which is critical when drilling hard or stringy materials that generate high side loads. The straight-cylindrical shank mounts directly into standard drill chucks, collet holders, and CNC machine spindles. It suits applications in precision machining shops, tool rooms, and maintenance facilities where tight tolerances and material integrity are required. The parallel web configuration and web-thinned geometry reduce thrust force requirements at the spindle.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction to C2 material grade for hardness and wear resistance in ferrous and exotic alloys\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces entry thrust and eliminates the need for a center punch\u003c\/li\u003e\n  \u003cli\u003eSlow spiral flute design controls chip flow in difficult-to-machine materials such as stainless steel and titanium alloy\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, parallel web configuration lowers axial cutting forces\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for applications where coating interaction with workpiece material is a concern\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to +0.0000 to -0.0005 inches for close-tolerance hole requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill chucks, collet holders, and CNC spindles that accept a straight-cylindrical shank.

Secure the straight-cylindrical shank fully in the chuck or collet before operation and verify runout before cutting. Solid carbide tooling is brittle and must not be subjected to side loading or interrupted cuts beyond the rated geometry. Always follow machine manufacturer guidelines for spindle speed and feed rate when drilling hard 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: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal)\u003c\/strong\u003e: 0.1250 inches\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\u003eOverall Length\u003c\/strong\u003e: 1-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7\/8 inches\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\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\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\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: 0.015 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: 74148792\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51741927014706,"sku":"74148792","price":18.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c7f1a3de800be1b214e6e9c5afedad31.jpg?v=1788834355","url":"https:\/\/voomisupply.com\/products\/hertel-74148792-screw-machine-drill-bit-0-125-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
