Why are my Hafco Metalmaster HM-46B Drill's tools or cutters breaking?
- A
  Antonio LambertAug 14, 2025
  If you are breaking tools or cutters on your Hafco Metalmaster Drill, several factors could be at play. The spindle speed or feed rate might be too fast, so try setting the spindle speed correctly or using a slower feed rate. The cutting tool could be too small; consider using a larger cutting tool and a slower feed rate. Overheating can also cause breakage, so use coolant or oil if appropriate for the application. Reduce the depth of cut and allow chips to clear. Finally, if the spindle is extended too far down, fully retract it and raise the table to increase rigidity.

  If the tool is loose in the spindle of your Hafco Metalmaster Drill, it could be due to a few reasons. First, the tool may not be fully drawn up into the spindle taper; tighten the drawbar. Second, there might be debris on the tool or in the spindle taper; clean both thoroughly. Third, you might be taking too big of a cut; lessen the depth of cut and allow chips to clear.

  If the headstock on your Hafco Metalmaster Drill is hard to raise, the issue might be with the headstock lock(s) or gib; try loosening or replacing the lock lever and adjusting the gib. Another possibility is that the headstock leadscrew is binding; clean and relubricate it along with the gears. Also, check if the gib is too tight and adjust it accordingly.

  If the spindle on your Hafco Metalmaster Drill overheats, it could be due to poor spindle bearing lubrication, in which case you should replace the spindle bearings. It's also possible that the spindle bearings are too tight; properly adjust the spindle bearing preload. Additionally, operating the mill at high speeds for an extended period can cause overheating; allow the mill to cool down.

  If your cutting results are not square with your Hafco Metalmaster Drill, it could be because the table and spindle are not at 90° to each other; square the spindle. Alternatively, the table travel might be inconsistent; adjust the gibs.
