Code 6718 Speeddrill+ Universal range. A hard tool coating forms a protective surface over the cutting edges and helps the drill withstand the friction, heat and abrasive wear generated during machining. This supports dependable cutting performance and helps preserve the accurately ground cutting geometry over a longer service period when the drill is used with the correct machining parameters.\u003c\/p\u003e\r\n\u003cp\u003eThe combination of ALTINDUR coating and solid carbide construction is particularly valuable in a universal drill intended to work across several steel grades, stainless steel, cast iron and selected non-ferrous materials.\u003c\/p\u003e\r\n\u003c\/div\u003e\r\n\r\n\u003cdiv class=\"info-products\"\u003e\r\n\u003ch3\u003eWhat does DIN 6537 K mean?\u003c\/h3\u003e\r\n\u003cp\u003e\u003cstrong\u003eDIN 6537 K\u003c\/strong\u003e identifies the short or stub-length form of this precision drill.
