Frequently Asked Questions

Kobalt or Craftsman bench grinder?

At $59 vs $69 for nearly identical specs, the Kobalt saves $10. The Craftsman has slightly better tool rests. Both are basic 6-inch grinders. The difference between them is smaller than the difference between either one and a DeWalt.

Should I upgrade the grinding wheels?

Yes. The stock gray wheels on budget grinders are coarse and run hot. Replace at least one wheel with a white aluminum oxide wheel (60 grit) for sharpening. Keep the original gray wheel on the other side for rough grinding. The upgrade costs about $15 to $20 per wheel.
