It carries a No. 33 wire gauge designation with a decimal diameter of 0.1130 inches (2.87 mm) and a 130-degree drill point angle suited for clean entry and reduced thrust. The fast spiral flute geometry and 35-degree helix angle promote efficient chip evacuation in through-hole drilling operations. The bright polished finish reduces friction and helps maintain dimensional accuracy at the cutting edge. Licensed electricians, PCB assembly technicians, and precision machine shops are the primary installers and users of this bit.\u003c\/p\u003e\n\u003cp\u003eThis bit is configured for right-hand cutting and features a tapered web for added rigidity at small diameters. With a 1\/8-inch (0.1250-inch decimal) shank diameter, it seats in standard drill chucks and CNC spindle collets without adapters. The 3\/8-inch flute length accommodates typical PCB stack thicknesses, and the 1-1\/2-inch overall length keeps runout manageable in high-speed spindles. Material applications include alloy steel, carbon steel, cast iron, high-temperature alloy, stainless steel, and titanium, making it usable well beyond board drilling in light machining work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for superior hardness and wear resistance at small diameters\u003c\/li\u003e\n  \u003cli\u003eNo. 33 wire size, 0.1130-inch decimal diameter for tight-tolerance through-hole work\u003c\/li\u003e\n  \u003cli\u003e130-degree drill point angle reduces thrust and improves entry accuracy\u003c\/li\u003e\n  \u003cli\u003eFast spiral flute with 35-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eTapered web design adds rigidity and reduces deflection at the cutting tip\u003c\/li\u003e\n  \u003cli\u003eBright polished finish minimizes friction and extends cutting life\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use precision drill bit for applications requiring a No. 33 wire gauge diameter; compatible with standard drill chucks and CNC collets accepting a 1\/8-inch shank.

Secure the shank fully in the collet or chuck before operation and verify runout is within tolerance before drilling. Solid carbide bits are brittle compared to high-speed steel — avoid lateral loading, side pressure, or interrupted cuts that can cause chipping or fracture. Power down and de-energize the spindle completely before changing or inspecting the bit.\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. 33\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1130 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 2.87 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches \/ 3.18 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3\/8 inch (0.4800 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches (38.10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Fast\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0003 to +0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Carbon Steel, Cast Iron, High Temperature Alloy, Stainless Steel, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright Polished\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 30211300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753094218034,"sku":"30211300","price":15.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95b33672eba165554b83b445b362b287.jpg?v=1788932747","url":"https:\/\/voomisupply.com\/products\/hertel-30211300-circuit-board-drill-bit-no-33-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
