At 0.0730 inch diameter, it features a 135-degree split point that reduces walking on entry and lowers the thrust required to start a hole. The two-flute regular-spiral design provides efficient chip evacuation over a 1.0-inch flute length, with an overall length of 2.0 inches. The NAS-designated heavy-duty grade makes it a reliable choice for production environments where consistent hole quality and tool durability are required.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for holemaking in stainless steel and cast iron, materials that demand a sharp, hard-wearing cutting edge and good heat resistance. The TiAlN coating significantly improves performance in these work-hardening and abrasive materials compared to uncoated HSS tooling. Typical applications include precision hole drilling in fabrication shops, maintenance and repair operations, and production machining environments. The straight cylindrical shank accepts standard drill chucks without adapters, and the right-hand cutting direction is compatible with conventional CNC, benchtop, and handheld drilling equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 49 wire size  -  0.0730 inch decimal diameter for precision small-hole work\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces entry walking and lowers feed force\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating increases heat and wear resistance for use in stainless steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty HSS construction rated to NAS specification\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute with web-thinned, tapered web for improved chip clearance\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in stainless steel and cast iron workpieces.

Secure the shank fully in a properly tightened drill chuck before operation. Use appropriate cutting fluid or coolant when drilling stainless steel or cast iron to reduce heat buildup, as this bit does not support through-coolant delivery. Inspect the cutting edges for wear or chipping before each use, and replace the bit if the point geometry is compromised to avoid workpiece damage or bit breakage.\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. 49\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0730 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1406 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.875 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 Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: NAS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Jobber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: 66693359\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51742475813170,"sku":"66693359","price":81.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b65b801e67ff4c3a9ae77e0783d378ce.jpg?v=1788837701","url":"https:\/\/voomisupply.com\/products\/hertel-66693359-no-49-hss-tialn-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
