It features a 120-degree drill point angle ground from high speed steel (HSS) stock and finished with a titanium nitride (TiN) coating for improved wear resistance and surface hardness. The cutting diameter is 4mm (0.1575 inches), the overall length is 55mm (2.165 inches), and the flute length is 12mm (0.472 inches). The straight cylindrical shank is also 4mm in diameter, making it compatible with standard drill chucks and collets. This drill belongs to GUHRING Series 567 and is suited for general-purpose spotting work in production and job shop environments.\u003c\/p\u003e\u003cp\u003eThis spotting drill is used to accurately locate and start holes, preventing drill walk on flat, curved, or angled workpiece surfaces. The 120-degree point angle is a widely used geometry for general-purpose spotting, compatible with standard twist drills of various included angles. The two-flute spiral design clears chips efficiently during short spotting passes. It is intended for use in CNC machining centers, manual mills, and drill presses where consistent hole placement is required. Typical materials machined include mild steel, alloy steel, aluminum, and similar metals in both production runs and prototype work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e120-degree drill point angle for general-purpose spotting geometry\u003c\/li\u003e\n\u003cli\u003eHigh speed steel (HSS) construction provides toughness across a wide range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eTiN coating increases surface hardness and extends tool life compared to uncoated HSS\u003c\/li\u003e\n\u003cli\u003eTwo-flute spiral design promotes efficient chip evacuation during spotting passes\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard chucks and collets without adapters\u003c\/li\u003e\n\u003cli\u003eSingle-ended design — GUHRING Series 567\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style spotting drill suitable for use in CNC machining centers, manual milling machines, and drill presses equipped with standard drill chucks or collet systems accepting a 4mm straight cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists and CNC operators in machine shop environments. Power down or fully stop the spindle before inserting or removing the tool from the chuck or collet. Ensure the shank is fully seated and the chuck or collet is torqued to the toolholder manufacturer specification before running the spindle. Verify runout after tool installation to maintain spotting accuracy, and use speeds and feeds appropriate for HSS tooling in the workpiece material being machined.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 120 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 4mm (0.1575 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 55mm (2.165 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 12mm (0.472 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4mm (0.1575 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eSingle\/Double Ended\u003c\/strong\u003e: Single\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\u003eSeries\u003c\/strong\u003e: 567\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: 9005670040000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51734756032818,"sku":"9005670040000","price":76.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8e69bbea309db54d3258e3634269b1e1.jpg?v=1788766627","url":"https:\/\/voomisupply.com\/products\/guhring-9005670040000-spotting-drill-4mm-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
