Built from C2-grade solid carbide with a bright\/uncoated finish, this bit delivers the rigidity and edge retention needed when working stainless steel, titanium alloy, nickel alloy, and heat-treated alloy stock. The 140-degree notched point geometry reduces entry force and improves centering on hard surfaces. A web-thinned construction further lowers thrust requirements. Right-hand cutting direction. Diameter tolerance is held to +0.0000 to -0.0005 inches, making this suitable for close-tolerance hole applications in toolrooms, maintenance shops, and production environments.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for machinists, tool-and-die technicians, and maintenance professionals working with ferrous and exotic alloys where high-speed steel tooling loses edge life too quickly. Typical applications include precision hole drilling in stainless steel fastener patterns, nickel alloy component repair, and chrome or heat-treated alloy fabrication. The small wire-gauge diameter makes it particularly useful in tight-clearance or fine-detail work where accurate hole sizing is critical. No coolant-through capability; external coolant or cutting fluid application at the drill point is the standard approach for hard-material drilling at this diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eC2-grade solid carbide construction for superior hardness and edge retention in alloy and stainless steel materials\u003c\/li\u003e\n  \u003cli\u003e140-degree notched point angle reduces entry thrust and improves self-centering on hard surfaces\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned design lowers axial cutting force at the drill tip\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.0000 to -0.0005 inches supports close-tolerance hole requirements\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — no coating buildup to affect dimensional accuracy at small diameters\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction, 2-flute configuration for chip evacuation in short-hole drilling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard straight-shank drill bit compatible with any drill chuck or collet system accepting a 0.0935-inch shank diameter.

Secure the shank fully in the chuck or collet before operation and verify runout at the tip before drilling into finished workpieces. When drilling hard alloys at this small diameter, apply external cutting fluid at the drill point to manage heat and extend tool life. Avoid excessive feed pressure, which can cause bit deflection or breakage in carbide tooling at small diameters.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 42\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.0935 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0935 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Notched\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: 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: Bright\/Uncoated\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: Chrome Alloy, Heat-Treated Alloy, Nickel Alloy, Stainless Steel, Steel, Titanium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 83246256\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51754853204274,"sku":"83246256","price":26.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3b7950237a21f30d84a2b23c921d7b30.jpg?v=1788949237","url":"https:\/\/voomisupply.com\/products\/hertel-83246256-straight-flute-drill-bit-no-42-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
