Built from high-speed steel with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction in repetitive drilling operations. The bit features a 135-degree split point that self-centers on contact, reducing the need for a center punch and minimizing walking on hard or smooth surfaces. At 1-13\/16 inches overall length, the shorter screw machine profile provides added rigidity compared to jobber-length bits, making it well suited for CNC machining centers, drill presses, and production line applications.\u003c\/p\u003e\u003cp\u003eThis bit is used in light manufacturing, metalworking shops, and production drilling setups where tight tolerances and consistent hole quality matter. The Size 39 wire gauge designation corresponds to 0.0995 inch diameter, placing it in the small-bore category. It is commonly used for tapping preparation, pilot holes, and close-tolerance work in ferrous and non-ferrous metals. A licensed machinist or tool-and-die professional would typically deploy this bit in a collet-style or standard drill chuck on a stationary or CNC machine tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiN coating reduces friction and increases surface hardness for longer tool life in repetitive drilling\u003c\/li\u003e\n\u003cli\u003e135-degree split point self-centers on contact, reducing setup time and drill walking\u003c\/li\u003e\n\u003cli\u003eScrew machine length body adds rigidity over jobber-length bits, improving accuracy in tight setups\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web reduces cutting force and heat buildup at the tip\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute efficiently clears chips from the cutting zone\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders without modification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard production drill bit for use in any drill chuck or collet system accepting a 0.0995 inch straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed and serviced by machinists, toolroom technicians, or trained production operators. Secure the shank firmly in the chuck or collet to the manufacturer-specified clamping depth before operation. Ensure the spindle is fully stopped and the machine is powered down before changing bits. Do not exceed the recommended feed rate or spindle speed for the workpiece material, as overfeeding a small-diameter bit can cause breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 39\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0995 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\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\u003eShank Diameter\u003c\/strong\u003e: 0.0995 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-13\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 13\/16 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\u003eWeight\u003c\/strong\u003e: 0.06 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: 02387322\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732461158706,"sku":"02387322","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/879a14655413327e059735133262d75c.jpg?v=1788743023","url":"https:\/\/voomisupply.com\/products\/hertel-02387322-screw-machine-drill-bit-size-39-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
