Built from heavy-duty 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 and reduces thrust requirements. At 2.25 inches overall length, this stub-length geometry provides added rigidity in drill press, CNC, and turret lathe applications where chatter and deflection need to be minimized. Machinists, millwrights, and maintenance mechanics are the primary users.\u003c\/p\u003e\u003cp\u003eThis bit is suited for production environments requiring consistent hole quality in ferrous and non-ferrous metals. The screw machine length format is a standard choice for CNC machining centers, turret lathes, and bench drill presses where a shorter, stiffer bit reduces runout. The 0.2031-inch diameter is sized for applications requiring a 13\/64-inch bore. Right-hand cutting direction is the standard orientation for conventional drill press and rotary tool use. The web-thinned parallel web improves chip evacuation and reduces the force needed to drive the bit through material.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point starts on contact, eliminating the need for a center punch\u003c\/li\u003e\n\u003cli\u003eTiN coating increases surface hardness and extends tool life in metal drilling applications\u003c\/li\u003e\n\u003cli\u003eHeavy-duty HSS construction handles interrupted cuts and hard materials\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web reduces thrust and improves chip flow\u003c\/li\u003e\n\u003cli\u003eStub screw machine length provides added rigidity versus jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with straight-cylindrical shank fits standard drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard screw machine length drill bit compatible with any 3-jaw drill chuck or collet system accepting a straight-cylindrical shank in the applicable size range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should follow standard machine shop safety practices. Secure the workpiece fully before drilling and confirm chuck tightness before spindle engagement. Use appropriate cutting fluid or coolant when drilling ferrous metals to manage heat, noting this bit does not support through-coolant delivery. Inspect the cutting edges for wear or chipping before each use and replace the bit if the TiN coating shows significant wear-through at the cutting lips.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 13\/64 inches (0.2031 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.1875 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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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\u003eWeb Configuration\u003c\/strong\u003e: Parallel 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: 0.2 pounds\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: 2386761\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51731134906674,"sku":"2386761","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6f4f7d0c69e3e2201f196500520abe69.jpg?v=1788727367","url":"https:\/\/voomisupply.com\/products\/hertel-2386761-screw-machine-drill-bit-13-64-inch-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
