10 Types of damage to drill and solutions Scratches on the margin Lack of coolant. Lack of lubrication in deep drilling of MQL machining. Bend of drill due to improper holding or insufficient rigidity drill length. Low rigidity or concentricity. Use more coolant. Solution Fix the workpiece tightly and check the concentricity. Check the precision of installment of drill. Low cutting speed. Wear on the margin Machining of all-metal or heat resisting alloy. Dissolution of back-tapper due to excessive drill wear. Unstable machining on the end of hole due to interrupted part. Lack of lubrication of coolant due to contacting the workpiece and outside of holder. Check grade and cutting parameters for material. Solution Check the types of machining. Check the kind and concentration of coolant. Chipping on the corner In interrupted machining. Chattering in drilling. (unstable clamping, low rigidity of machine and bending) Chattering due to concentricity of drill. Check the machining part. Low cutting speed. Check the machinability of the machine. Check the precision of drill installment. (below 0.02mm) Solution Fix the workpiece accurately. Wear on the bevel Machining in low cutting speed. Machining in free-cutting steel. Chip erosion of flute. Lack of coolant. Solution Increase cutting speed. Reduce the honing. Low thinning angle. Use more coolant. Chipping on the bevel Pre-treatment on the center of hole makes fracture on the cutting edge partially. Unstable chip evacuation due to step drilling. Chattering in drilling and less precision of installment. Check the pre-machining. Solution Check the clamping of workpiece. Check the precision of drill installment. (below 0.02mm)

11 Types of damage to workpiece and check-point Poor surface roughness (bending, scratch) Low rigidity of machine, improper clamping of workpiece. Poor concentricity, lack of coolant. Solution Clamp the workpiece properly and check the concentricity. Use more coolant and increase the pressure. Burr in the end of hole High feed, excess honing on the cutting edge. Too much wear and chipping. Solution Reduce feed, use a new drill. Increase point angle or reduce honing. Flaking the end of hole In machining of low toughness materials as cast iron. Rapid feed and much honing on the cutting edge. Too much wear and chipping. Solution Reduce the feed. Reduce honing on the cutting edge. 11 Use a new drill. Thermal deformation and oxidation of the end of hole Rapid feed. Lack of coolant. Solution Reduce the feed and honing on the cutting edge. Use more coolant and use a new drill. Excessive cutting load. Too much wear and chipping. Check-point of drilling Clamping of workpiece Revolution of the main axis of machine Coolant (pressure, flow, concentration) Chip evacuation Holder Run-out of drill (Max.0.03mm) Supply of coolant Supply enough coolant to the beginning of the hole. Minimum oil pressure of coolant : above 5 bar Minimum flow : above 5l/min
