This Sideways Cutting Drill Saw Bit is coated in Titanium Nitride (TiN) for a supremely high melting point of 5,306 degrees Fahrenheit. Titanium Nitride coated bits last up to six times longer than standard high speed drill bits by reducing friction, and their cutting edges stay sharper longer. It is also great for making holes in wood and metal. The 135-degree split point reduces feed pressure for easier penetration without adding extra stress or difficulty to your work. This is a one-piece quick change shank drill saw, ideal for drilling a slot or opening up holes in wood, MDF, and plywood. It functions as a rotary reamer and file. Specifications: Diameter (D1) = 6 mm, Overall length = 90 mm, Shank Diameter = 1/4" hex. Weight: 0.05952481074 pounds. Manufacturer: AB Tools.
