The head is manufactured from solid carbide with a ZrN (zirconium nitride) coating, which extends tool life when cutting hard and abrasive materials. At 3 inches overall length with a 1\/8 inch shank diameter, this burr fits standard die grinders and rotary tools. The double-cut tooth pattern produces faster stock removal than single-cut, while still leaving a reasonably smooth surface finish. Maximum rated speed is 50,000 RPM.\u003c\/p\u003e\u003cp\u003eThis burr is suited for use on steel, stainless steel, cast iron, superalloys, and titanium. The inverted cone geometry makes it well-suited for undercutting, deburring angled edges, and working in recessed areas where a straight cylindrical burr cannot reach. It is typically used by machinists, tool and die workers, welders, and maintenance technicians performing weld cleanup, port work, or precision material removal in tight geometries.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eInverted cone head shape for undercutting and angled deburring work\u003c\/li\u003e\n\u003cli\u003eDouble-cut tooth style for fast stock removal on hard metals\u003c\/li\u003e\n\u003cli\u003eSolid carbide head with ZrN coating for extended tool life on hard materials\u003c\/li\u003e\n\u003cli\u003eRated to 50,000 RPM for use with standard high-speed die grinders\u003c\/li\u003e\n\u003cli\u003eIncluded angle of 10 degrees provides precise, controlled cutting geometry\u003c\/li\u003e\n\u003cli\u003e1\/8 inch shank fits the most common collet size on rotary and die grinder tools\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit burr for die grinders, rotary tools, and flex-shaft machines with a 1\/8 inch collet.

Ensure the tool is fully powered off and the collet is completely loosened before inserting or removing the burr. Inspect the shank for cracks or wear before each use, and do not exceed the 50,000 RPM maximum speed rating. Eye protection and appropriate PPE are required when operating rotary cutting tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Shape\u003c\/strong\u003e: Inverted Cone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTooth Style\u003c\/strong\u003e: Double Cut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Coating\u003c\/strong\u003e: ZrN (Zirconium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 10 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 50,000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys, Titanium, Hard Materials\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.019 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112809\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SN-42L3DC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":68388956143922,"sku":"SN-42L3DC","price":26.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5ead3551ef8c77a8f19327aa68557dcb.jpg?v=1793904926","url":"https:\/\/voomisupply.com\/products\/value-collection-sn-42l3dc-inverted-cone-carbide-bur","provider":"Voomi Supply","version":"1.0","type":"link"}
