The bit features a fast spiral flute geometry with a 35-degree helix angle and a tapered web configuration, which promotes efficient chip evacuation in small-diameter drilling applications. A bright polished finish reduces friction at the cutting edge. The 1\/8-inch straight shank and 1.5-inch overall length make this bit compatible with standard precision drill presses and CNC drilling setups used in circuit board fabrication and small-part machining work.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling printed circuit boards and small-diameter through-holes in precision manufacturing and repair environments. The solid carbide construction handles hard and abrasive substrates that would prematurely wear high-speed steel tooling. Material applications listed by the manufacturer include alloy steel, carbon steel, cast iron, high-temperature alloy, stainless steel, and titanium, making this a versatile small-diameter drill for machine shops, electronics fabricators, and maintenance technicians working with tight-tolerance holes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 53 wire size with 0.0595-inch decimal diameter for precise small-hole drilling\u003c\/li\u003e\n\u003cli\u003e130-degree point angle optimized for entry accuracy and reduced walking on hard substrates\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction resists wear on abrasive and hard materials\u003c\/li\u003e\n\u003cli\u003eFast spiral flute with 35-degree helix angle promotes chip clearance in deep holes\u003c\/li\u003e\n\u003cli\u003eTapered web configuration adds rigidity to the cutting tip\u003c\/li\u003e\n\u003cli\u003eBright polished finish reduces friction and built-up edge at cutting surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in precision drill presses, CNC drilling machines, and hand-held drill chucks accepting a 1\/8-inch straight shank.

Secure the 1\/8-inch shank firmly in a collet or drill chuck before operation and verify runout is within acceptable limits for the application. Use cutting fluid appropriate for the workpiece material to extend tool life. Inspect the cutting edge before each use, as solid carbide is brittle and susceptible to chipping if dropped or subjected to side loading.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 53\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0595 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 1.51 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\u003eCoating\/Finish\u003c\/strong\u003e: Bright Polished\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (Inch)\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (mm)\u003c\/strong\u003e: 3.18 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length (Inch)\u003c\/strong\u003e: 3\/8 inch (0.4000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 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\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 30205950\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51754709451058,"sku":"30205950","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/34e7c8221b8f1f87fc2e8dd2c5eb9c85.jpg?v=1788948017","url":"https:\/\/voomisupply.com\/products\/hertel-30205950-no-53-solid-carbide-circuit-board-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
