Built from solid carbide, it offers significantly higher hardness and heat resistance compared to high-speed steel alternatives. The 135-degree split point reduces walking and allows the bit to self-center on contact without a pilot hole. At 1-15\/16 inches overall length, this stub-length geometry provides maximum rigidity and minimal deflection in CNC machining centers, drill presses, and turret lathes. The straight cylindrical shank fits standard drill chucks. This bit is sold individually.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for machining cast iron, nickel alloys, stainless steel, titanium alloys, and tool steel — materials that demand a cutting tool with high compressive strength and thermal stability. The slow spiral flute geometry is optimized for these hard and abrasive workpiece materials, promoting chip clearance without work-hardening the bore wall. Typical applications include production shops, toolrooms, and maintenance departments where consistent hole quality in tough alloys is required. A licensed machinist or tool-and-die professional would typically operate this tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for superior hardness and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point for self-centering and reduced thrust force\u003c\/li\u003e\n\u003cli\u003eSlow spiral flute design optimized for cast iron, stainless steel, titanium alloy, and nickel alloy\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length provides maximum rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish — no coating buildup that could affect tight diameter tolerances\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, straight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or new-install tooling option for any drill press, CNC machining center, or turret lathe accepting a straight cylindrical shank drill bit in the 0.1000 to 0.1500 inch decimal diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and remove this bit only with the machine fully powered down and the spindle at a complete stop. Solid carbide is brittle — avoid side loading, interrupted cuts without proper feeds and speeds, or dropping the bit on hard surfaces. Secure the shank fully within the chuck jaws to the recommended engagement depth per your machine manufacturer guidelines. Inspect the cutting edges under magnification before each use; carbide chipping is not always visible to the naked eye.\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\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-15\/16 inches (1.9375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5\/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\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.1000 to 0.1500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 16705006\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51733689467186,"sku":"16705006","price":22.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/416ab1370bd5c0a81bd5d1ac4e2b1ebc.jpg?v=1788758212","url":"https:\/\/voomisupply.com\/products\/hertel-16705006-screw-machine-drill-bit-no-29-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
