More and more is being demanded from cutting tools and also solid carbide drills during machining, which in turn leads to more frequent wear and application problems. If problems arise when machining with solid carbide drills, the following tips and tricks should help you:
A common reason for built-up edges is that the cutting speed is too low, excessive honing of the main cutting edge or an uncoated cutting edge. If you are having problems with built-up edges, the following might help:
Unstable conditions, significant run-out errors or an interrupted cut can cause corners to break off. When problems with corners breaking off arise, try the following:
Excessive cutting speeds, insufficient feeds or a clearance angle that is too low can cause major flank wear. For reduced flank wear, we recommend
Edge breakage on the main cutting edge often occurs due to unstable conditions, interrupted cut or the maximum wear width is exceeded. Selecting an incorrect tool type can also be the cause. Try the following in this case:
Unstable conditions, significant run-out errors or inadequate tapering can cause round chamfer wear. Incorrect emulsion or one that is too thin can also be the cause. If you are having problems with round chamfer wear, try the following:
Unstable conditions, significant run-out errors or interrupted cuts are often the cause of scoring on the tool flank. This problem occurs in particular with abrasive materials. The following can help:
Cutting speed too low, excessive feed or excessive honing of the main cutting edge can cause major wear at the chisel edge. The following can help here:
If you are struggling with edge breakage at the intersection, at the drill point or on the main cutting edge, the reason may be that the clearance angle is too small, excessive honing of the main cutting edge or the incorrect tool has been selected. Try the following in this case:
Excessive cutting speeds, insufficient emulsion, incorrect or no corner honing can cause plastic deformation of the cutting edges. The following can prevent the deformation of the cutting edges:
Poor surface quality is often caused by significant run-out errors, too little cooling or unstable conditions. The following can optimise the quality of the surface:
Heavy burring on the hole exit can be caused by excessive feed or excessive honing of the main cutting edge. Try the following in this case:
