It carries a No. 49 wire gauge size, which corresponds to a decimal diameter of 0.0730 inches. The 135-degree split-point geometry reduces walking on entry and requires less thrust than a conventional 118-degree point. With an overall length of 1-11\/16 inches and a matching flute length, this is a stubby, rigid tool built for close-tolerance hole-making in production and maintenance environments. The bright, uncoated finish is standard for solid carbide tools used across a range of difficult materials.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for machining cast iron, nickel alloys, stainless steel, titanium alloys, and tool steel. Its short screw machine length provides maximum rigidity, making it a strong choice for CNC machining centers, drill presses, and manual machines where chatter and deflection must be minimized. The slow spiral flute design helps control chip evacuation in materials that produce short, brittle chips. It is typically selected by machinists, tool-and-die professionals, and maintenance technicians working in precision or high-production settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eNo. 49 wire size, 0.0730 inch decimal diameter\u003c\/li\u003e\n\u003cli\u003e135-degree point angle reduces thrust and improves self-centering on entry\u003c\/li\u003e\n\u003cli\u003eSlow spiral flute geometry suited to short-chipping materials such as cast iron and titanium alloy\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish compatible with a wide range of cutting fluids and dry applications\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide drill bit for standard straight-shank drill chucks and collets accepting a 0.0730 inch shank diameter in machining and maintenance applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or maintenance technicians familiar with carbide tooling. Secure the straight-cylindrical shank fully in a collet or drill chuck before operation, and verify runout is within acceptable limits, as carbide is brittle and sensitive to lateral loading. Always power down and lock out the machine before changing tooling. Avoid using carbide drills in hand-held drill applications where side loading is difficult to control.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Slow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Nickel Alloy, Stainless Steel, Titanium Alloy, Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 16704850\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747532800306,"sku":"16704850","price":19.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f334d1b6536963df2fb5f61ff8114452.jpg?v=1788882034","url":"https:\/\/voomisupply.com\/products\/hertel-16704850-screw-machine-drill-bit-no-49-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
