Built from high speed steel (HSS) with a black and gold oxide coating, this bit runs a 135-degree split point that reduces walking and cutting force at the start of each hole. The overall length is 1.625 inches with a flute length of 0.6875 inches. Right-hand spiral fluting and a straight cylindrical shank make it compatible with standard drill chucks. The heavy-duty grade construction supports demanding production and maintenance drilling tasks.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for technicians and machinists drilling into steel and cast iron in light manufacturing, mechanical service, HVAC, electrical, and general trade applications. The small wire gauge diameter makes it a common choice for pilot holes, tap drilling, and precision clearance holes where tight tolerances matter. The split point geometry is particularly useful when drilling without a center punch, reducing the need for a separate spotting operation. It is sold individually and fits standard keyless or keyed drill chucks used in handheld and bench-mounted drilling equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge No. 59 diameter  -  0.0410 inches decimal equivalent for precision small-hole work\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces drill walking and lowers required feed force\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles steel and cast iron applications\u003c\/li\u003e\n  \u003cli\u003eBlack and gold oxide coating provides lubricity and surface protection\u003c\/li\u003e\n  \u003cli\u003eRight-hand regular spiral flute efficiently clears chips from the bore\u003c\/li\u003e\n  \u003cli\u003eTapered web and straight shank design for use in standard drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use jobber drill bit for applications requiring a wire gauge No. 59 straight-shank drill in standard drill chucks and handheld or bench drilling equipment.

Secure the workpiece before drilling to prevent movement and bit breakage at this small diameter. Ensure the chuck is tightened fully before operation and that the drill bit is centered in the chuck jaws. Consult tooling speed-and-feed charts for HSS bits in steel and cast iron before setting spindle RPM.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 59\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0410 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\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Black\/Gold 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\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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: 0.6875 inches (11\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.625 inches (1-5\/8 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: 0.0410 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.9374 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\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: 0.8 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: CLE-LINE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C18112\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLE-LINE","offers":[{"title":"Default Title","offer_id":52056189305138,"sku":"C18112","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d58b798d5f1a66a19890d8d0827a0c51_eb89e6f8-1258-43cf-864e-19ac8841a7f3.jpg?v=1790038089","url":"https:\/\/voomisupply.com\/products\/cle-line-c18112-jobber-drill-bit-wire-size-59-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
