- Our jobber length, precision ground carbide drills are designed for high feed rates with good chip disposal. Unstable drilling can result in a broken bit. Premium bright finish multi-purpose solid carbide drill bits provide better rigidity than high speed steel bits. It will chew down into most anything but the hardness makes them brittle with virtually no plasticity.
Spiral flutes are constructed with a higher flute angle to remove chips more easily. Our tungsten carbide wc bits has the advantage of cutting metal either "wet" or "dry" and they provide solutions for many businesses such as aerospace drilling jobs for aircraft mechanics, hobby supply, precision machining, etc.
Specs flute length: 1-5/8 inch, overall length: 2-3/4 inch, drill size: 3/16 inch // tungsten Carbide Grade ISO: K20 // Binder: %8 Cobalt // Hardness: 91. 3 hra // Uncoated. Recommended for use on aircraft metals chrome titanium inconel stainless steel alloys steel Low-Medium-High Carbon Steel Aluminum Copper Glass Plastics Composite Materials Cast Iron -- Our Carbide drills stay sharp many times longer than traditional steel bits making them ideal for the toughest of applications! Optimal design for metal work 118° four facet point angle minimizes drill wander and assures accurately sized holes.
It is a very hard material being a 9 on the Mohs scale where diamond is a 10 and hard steel around 5. Tungsten carbide is a composite material, it is a composite of tungsten carbide powder mixed with cobalt as a binder metal, although it looks like a metal, the resulting material is more like a ceramic than a metal. Smooth finish on the bits increases chip flow.
