Built from cobalt high-speed steel with a titanium aluminum nitride (TiAlN) coating, this bit handles hard materials and elevated cutting temperatures that would degrade standard HSS tooling. It features a 135-degree split point for fast penetration and reduced walking on entry. The straight-cylindrical shank seats securely in standard drill chucks and machine spindles. Overall length is 2-3\/16 inches, keeping it rigid and reducing deflection in close-clearance setups. Machinists, tool and die techs, and maintenance mechanics are the primary users.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for production drilling and repair work in metal shops, maintenance facilities, and manufacturing environments. The screw machine length profile  -  shorter than jobber length  -  improves rigidity and accuracy in drill press, turret lathe, and CNC machine applications. The size 17 wire gauge diameter of 0.1730 inches falls within the 0.1500 to 0.2000 inch range, making it useful for tapping prep, clearance holes, and precision through-holes in steel, stainless, cast iron, and other ferrous materials where cobalt tooling is appropriate.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt high-speed steel construction for heat and wear resistance in hard-material drilling\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life and reduces friction at elevated cutting speeds\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces thrust force and self-centers on entry without a center punch\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, parallel web configuration improves chip evacuation and reduces heat buildup\u003c\/li\u003e\n\u003cli\u003eScrew machine length body at 2-3\/16 inches OAL provides extra rigidity over jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute for standard clockwise rotation in conventional drilling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use screw machine drill bit for any drill press, turret lathe, or CNC spindle accepting a straight-cylindrical shank in the 0.1730-inch diameter class.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or maintenance mechanics familiar with metalworking tooling. Power down and de-energize the machine before changing or seating the bit in the chuck. Confirm shank seating and chuck tightness before initiating a cut. Do not exceed the recommended speed and feed for the workpiece material and bit diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 17\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1730 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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: 2-3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.1500 to 0.2000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\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: 74132143\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51740343009586,"sku":"74132143","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/17e48ceecbbf0425d69082b1cdd23eb5.jpg?v=1788824449","url":"https:\/\/voomisupply.com\/products\/hertel-74132143-size-17-cobalt-drill-bit-tialn-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
