Flat Drill Design, Uses and Maintenance
Flat Drill is a simple cutting tool for producing shallow, flat-bottomed holes and enlarging existing bores. Learn its design, applications, setup, inspection, sharpening, and maintenance.
The cutting edges, point geometry, diameter, shank, clearance, and material must match the workpiece and machine. High-speed steel and carbide are common choices. Correct spindle speed, feed, alignment, coolant, and rigid workholding reduce chatter, heat, edge wear, and dimensional error while improving hole finish and tool life.
Inspect runout, cutting-edge wear, cracks, buildup, and symmetry before use. Sharpen both edges evenly to preserve balance and accurate cutting. A qualified cutting tool manufacturer can recommend a suitable specification. General drill bit information also explains tool geometry, materials, and applications.
