Built from M42 cobalt high-speed steel and finished with a gold oxide coating, this bit delivers extended tool life and heat resistance at high cutting speeds. The 135-degree split point reduces walking and cutting pressure at entry, making it well suited for hard-to-start surfaces. The straight-cylindrical shank measures 0.021 inches in diameter, with an overall length of 1 inch and a flute length of 0.25 inches. A licensed HVAC tech, pipefitter, or maintenance machinist would reach for this bit when tight tolerances are required in small-diameter work.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use in metal drilling applications where a small-diameter, high-performance bit is required. Its primary workpiece material rating is aluminum, though the M42 cobalt construction makes it suitable for a range of metals encountered in mechanical and industrial service work. The regular spiral flute and right-hand cut configuration are standard for most bench-top and handheld drilling operations. Web-thinned geometry reduces thrust force during penetration, which matters in production or repetitive drilling scenarios.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt high-speed steel construction for extended heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces bit walking and lowers required thrust force\u003c\/li\u003e\n\u003cli\u003eGold oxide coating provides lubricity and added surface hardness\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web geometry for cleaner entry and reduced cutting load\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flute for standard drill press and handheld use\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 Type J specification for dimensional and performance consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard-stock jobber drill bit for applications requiring wire size 75 at 0.021 inches diameter, conforming to NAS 907 Type J specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed and used by machinists, millwrights, and skilled trade technicians using standard drill chucks compatible with a 0.021-inch straight-cylindrical shank. Secure the shank fully in the chuck before operation to prevent slippage. Use cutting fluid appropriate for the workpiece material to extend bit life and maintain dimensional tolerance. Inspect the cutting edges before each use — M42 cobalt bits can chip if used on hardened steel beyond their rated capacity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 75\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0210 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42 Cobalt High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish \/ Coating\u003c\/strong\u003e: Gold Oxide\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\u003eFlute Length\u003c\/strong\u003e: 0.25 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: 0.0210 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: NAS 907 Type J\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2213\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: CLEVELAND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C70208\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51723210326322,"sku":"C70208","price":83.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68e71fac92ed610a068aecfe4d190284_566af8fa-0c98-42fd-b9f8-e5adead559fd.jpg?v=1788601975","url":"https:\/\/voomisupply.com\/products\/cleveland-c70208-cobalt-jobber-drill-bit-wire-75","provider":"Voomi Supply","version":"1.0","type":"link"}
