Why is my Grizzly G8689Z breaking tools or cutters?
- P
  Pamela SmithAug 12, 2025
  If your Grizzly Power Tool is breaking tools or cutters, it might be due to several reasons. The spindle speed could be too fast for the depth of cut, cutting tool size, or workpiece material. Try reducing the spindle speed and feed rate, and take lighter cuts. Ensure you are using the proper lubricant for the operation, as improper or no lubricant can cause the cutting tool to overheat. Check if the cutting tool is dull or incorrect; if so, sharpen or replace it, selecting a better tool for the operation. Also, consider if the cutting tool is too small; using a larger cutting tool and slower feed rate may help. Finally, avoid taking too big of a cut by lessening the depth of cut and allowing chips to clear.

  If your Grizzly Power Tool workpiece or tool vibrates or chatters during operation, first check that the table lock handles are tight. If not, tighten them. Ensure the workpiece is properly clamped on the table or in a vise. If the spindle speed or feed rate is too fast, reduce them. Also, check if the gibs are too loose in the table and tighten them if necessary. Replace or sharpen the bit if it's chattering, index the bit to the workpiece, and reduce the feed rate. Finally, the chuck or cutter may be at fault, so replace an unbalanced chuck or replace/sharpen the cutter.

Lastly, the X-/Y-axis leadscrews might be binding, so clean and lubricate them.

  If the headstock on your Grizzly Power Tool is hard to move, first check if the headstock lock handle is tightened down and loosen it. Ensure the downfeed lever hub teeth are disengaged for rapid downfeed and engaged for micro downfeed. Frequently clean away chips during operations, as they can load up on the column ways. Clean and lubricate the column ways and rack. If the gib is too tight, loosen it. Finally, the headstock counterbalance spring might be at fault, in that case replace the spring assembly.
