THE new Delta-C drill from Sandvik Coromant allows considerably higher feeds, up to 50 per cent higher than previously possible, along with a substantial increase in cutting speeds.
The bronze coloured all-round grade GC1220 provides a balance between toughness and wear resistance and the strong multi-layer coating contributes to the edge security and a longer tool life.
The Delta-C drill in GC1220 covers a very wide application area and can be used in most materials. This makes it easy to choose and keeps inventory costs down.
The straight cutting edge geometry makes re-grinding easier and allows for several regrinds.
The CoroDrill Delta-C in combination with CoroGrip high precision chucks provides outstanding stability and minimum run-out in precision hole making.
