Built from high-speed steel with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction compared to uncoated HSS bits. The 135-degree split point starts on contact without a center punch, reducing walking on hard or smooth surfaces. At 1.75 inches overall length, this stub-length geometry provides added rigidity for drilling in tight clearance situations where a jobber-length bit would flex or chatter. The web-thinned, parallel web construction promotes clean chip evacuation through the spiral flute.\u003c\/p\u003e\u003cp\u003eThis bit is suited for production drilling, screw machine operations, and short-hole work in ferrous and non-ferrous metals. The straight-cylindrical shank seats securely in three-jaw chucks, drill press chucks, and CNC toolholders. Its stub length and 0.75-inch flute length make it a practical choice for sheet metal work, fixture drilling, and any setup where rigidity and hole accuracy matter more than depth capacity. Sold individually, this bit is sourced in multiples of 12 to meet production consumption needs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiN coating extends tool life and lowers cutting friction versus bare HSS\u003c\/li\u003e\n\u003cli\u003e135-degree split point self-centers on entry, eliminating the need for a center punch\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web promotes efficient chip evacuation through the spiral flute\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length adds rigidity and reduces deflection in short-hole drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting spiral flute compatible with standard drill presses and CNC spindles\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard three-jaw and keyless chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or production-stock drill bit for screw machine operations and general metalworking setups using standard straight-shank chucks.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this bit should be performed by a machinist or qualified trade professional familiar with drilling speeds and feeds for HSS tooling. Ensure the drill press, lathe turret, or CNC spindle is fully stopped and locked out before changing tooling. Secure the straight-cylindrical shank fully within the chuck jaws to the full shank engagement depth to prevent slippage. Use cutting fluid appropriate to the workpiece material to preserve coating life and maintain hole tolerance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 44\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0860 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\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\u003eShank Diameter\u003c\/strong\u003e: 0.0860 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\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: 0.03 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: 02387371\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51746193670450,"sku":"02387371","price":56.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da5bace9200f0edeb01d04da4b9ea617.jpg?v=1788866962","url":"https:\/\/voomisupply.com\/products\/hertel-02387371-screw-machine-drill-bit-size-44-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
