Built from high speed steel with an oxide coating, it runs a 135-degree split point that self-centers on contact and reduces the need for a center punch. The bit measures 2.875 inches overall length with a 1.75-inch flute length, and carries a 0.1360-inch decimal diameter. The heavy-duty grade construction suits repetitive production drilling as well as maintenance and repair work. Machinists, tool-and-die workers, HVAC technicians, and electricians reach for this size when drilling pilot holes or clearing standard wire-size clearance holes.\u003c\/p\u003e\u003cp\u003eThis jobber drill is sized to the No. 29 wire gauge standard, which corresponds to a 0.1360-inch diameter. It fits drill chucks on portable hand drills, drill presses, and CNC machining centers that accept a 0.1360-inch straight cylindrical shank. The oxide coating provides mild lubricity and surface hardness for extended cutting life in ferrous materials. Its regular-spiral, two-flute design clears chips efficiently in through-hole and blind-hole applications across light steel, aluminum, brass, and similar metals.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 29 wire size, 0.1360-inch diameter — matches standard wire-gauge drill charts\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning self-centers and reduces thrust requirement\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with oxide coating for extended tool life in ferrous metals\u003c\/li\u003e\n\u003cli\u003e2.875-inch overall length with 1.75-inch spiral flute for chip evacuation in deeper holes\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard 3-jaw drill chucks without an adapter\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction, two regular-spiral flutes, tapered web configuration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard jobber-length drill bit for use in any drill press, hand drill, or machining center accepting a 0.1360-inch straight cylindrical shank.

Always wear appropriate eye protection and secure the workpiece before starting the spindle. When drilling steel, apply cutting fluid to extend bit life and improve hole finish. Inspect the cutting edges for wear or chipping before each use and replace the bit when the split point shows visible dullness to avoid work-hardening the base material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 29\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1360 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered web-thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1360 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Jobber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble Margin\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: NAS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 84581032\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51736987828530,"sku":"84581032","price":37.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/232cb8428aaccfc5ef71fa5e7843df7c.jpg?v=1788782755","url":"https:\/\/voomisupply.com\/products\/hertel-84581032-jobber-drill-bit-no-29-hss-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
