Built to Series 723 standards, it features a 90-degree drill point angle and a 1\/4 inch (0.2500 inch) cutting diameter on a straight-cylindrical shank of equal diameter. The 70mm overall length and 17mm spiral flute length make this a compact, rigid tool suited for CNC machining centers and manual drill presses alike. The bright uncoated finish keeps the carbide substrate exposed for use across a wide range of general-purpose materials. Right-hand cutting direction is standard.\u003c\/p\u003e\u003cp\u003eThis spotting drill is intended for general-purpose spotting and center-locating applications in machining environments. It is typically used by machinists and toolroom professionals working in production shops, job shops, or maintenance departments. The single-ended, two-flute spiral design helps evacuate chips efficiently during short spotting cycles. At 70mm OAL, it fits standard toolholders and collet chucks sized for 1\/4 inch shanks without extended-reach adapters in most setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e90-degree drill point angle for accurate hole spotting and drill walking prevention\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and extended tool life versus HSS alternatives\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for general-purpose materials\u003c\/li\u003e\n\u003cli\u003eTwo-flute spiral geometry promotes chip evacuation during spotting cycles\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for direct collet or chuck mounting\u003c\/li\u003e\n\u003cli\u003eSingle-ended design in compact 70mm OAL for standard toolholder clearance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose OEM-style spotting drill compatible with standard 1\/4 inch straight-shank collet chucks and drill chucks used in CNC machining centers and manual drill presses.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the spindle fully stopped and machine power isolated per shop safety protocols. Seat the straight-cylindrical shank fully into the collet or chuck and tighten to the toolholder manufacturer's specified clamping method before running. Solid carbide tooling is brittle — avoid side loads, interrupted cuts beyond the tool's rated application, or dropping the tool on hard surfaces. Confirm runout with a dial indicator before production use to maximize tool life and hole position accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inch \/ 6.35mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 70mm (2.7559 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 17mm (0.6693 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 723\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Spotting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle\/Double Ended\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GUHRING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9007230063500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51748862722354,"sku":"9007230063500","price":131.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ca08397affb100d8d02b48726fc678ad.jpg?v=1788899751","url":"https:\/\/voomisupply.com\/products\/guhring-9007230063500-spotting-drill-90-degree-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
