Drill Bit Breakage
Drill bit breakage refers to the fracturing of a drill bit during the drilling process. This can be caused by excessive force, improper handling or material fatigue. Drill bit breakage is not only frustrating but can also lead to injury and damage to the workpiece.
-
Overloading: Excessive pressure on the bit causes it to become overstressed.
-
Material defects: Inferior quality drill bits or material fatigue increase the risk of fracture.
-
Incorrect speed: A drilling speed that is too high or too low may destabilise the bit.
-
Improper handling: Misuse of the drill can lead to overloading or jamming.
Preventive Measures:
To prevent drill bit breakage, selecting the appropriate drilling speed is crucial. High-quality drill bits should be used, and materials must be processed correctly. Additionally, regularly checking the bits for wear helps avoid potential breakage.
Consequences and Actions After Drill Bit Breakage:
If a drill bit breaks, it must be replaced immediately to avoid further damage. It is also important to identify the cause of the break and, if necessary, adjust the drilling process accordingly.
