What is a Flat Head Drill Used for?

Flat drill is a woodworking tool. The bit with flat head is made of very hard alloy. The cutting part of the woodworking flat drill is ground into a flat body, and the main cutting edge grinds out the sharp angle, the rear angle and forms a cross edge; The secondary cutting edge grinds out the rear angle and secondary deflection angle and controls the drilling diameter. The flat drill has small front angle, no spiral groove and difficult chip removal, but it is simple to manufacture and low in cost. It is widely used for machining small holes with a diameter of less than 1mm. Due to the great improvement in structure and the above advantages, flat drills are also used when machining holes with a diameter of more than 35mm on automatic lines and CNC machine tools.
