Shorter than a jobber-length bit, the screw machine format reduces overhang and increases rigidity, making it well suited for tight-clearance drilling and high-production work. The bit runs a No. 5 wire gauge size, equal to 0.2055 inches in diameter, with a 135-degree split-point geometry that starts on contact without a center punch. Two slow-spiral flutes clear chips efficiently, and the straight cylindrical shank seats directly in standard drill chucks and collets. Overall length is 2.375 inches with a flute length of 1.25 inches. The bright uncoated finish means no coating buildup that could affect hole tolerance in tight-spec applications.\u003c\/p\u003e\u003cp\u003eThis bit is intended for drilling hard and difficult-to-machine materials including cast iron, nickel alloys, stainless steel, titanium alloys, and tool steel. The 135-degree point angle and solid carbide construction handle work hardening and abrasive materials better than high-speed steel alternatives. Typical use cases include production drilling on CNC machining centers, drill presses, and screw machine setups where consistent hole quality and tool life in hard stock are required. Machinists and tool-and-die professionals working in metalworking and aerospace fabrication shops are the primary installers and users of this bit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction provides superior hardness and wear resistance in abrasive and hard-to-machine metals\u003c\/li\u003e\n\u003cli\u003e135-degree split point starts on contact and reduces walking without a center punch\u003c\/li\u003e\n\u003cli\u003eScrew machine length body increases rigidity and reduces deflection in close-tolerance holes\u003c\/li\u003e\n\u003cli\u003eTwo slow-spiral flutes engineered for effective chip evacuation in gummy or stringy materials\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish maintains true diameter and avoids coating interference in precision-tolerance bores\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks and collet systems without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard drill chucks, collet holders, and screw machine spindles accepting a 0.2055-inch straight cylindrical shank.

Secure the shank firmly in the chuck or collet to the manufacturer-specified clamping depth before operation. Coolant-through is not supported by this bit; use external coolant or cutting fluid appropriate for the workpiece material when drilling hard alloys. Inspect the cutting edges for chipping before each use, as carbide is brittle and edge damage can cause sudden bit failure or oversize holes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2055 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\u003eShank Diameter\u003c\/strong\u003e: 0.2055 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.25 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: 0.03 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: 16704330\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51746934554930,"sku":"16704330","price":35.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f351777c1f148c49a2692f576827d413.jpg?v=1788874728","url":"https:\/\/voomisupply.com\/products\/hertel-16704330-screw-machine-drill-bit-no-5-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
