Cobra Carbide’s Blackmamba series of coolant-fed drills features a flute design and cutting edge geometry that enables drilling to a depth of eight times the tool diameter. The drills are said to feature enhanced self-centering characteristics, optimized chip flow, high cutting rates and high productivity. They also eliminate the pecking cycle, reducing drilling time compared to conventional drilling, the compan says.
Editor PickCan Additive Manufacturing Increase Milling Feed Rates?
With PCD tooling, yes it can. The diamond cutting edges demand a large number flutes to realize their full effectiveness. Traditional methods for making cutter bodies limit the number of flutes, but 3D printing is delivering tools with higher flute density and other enhancements as well.
