KSEIBI Drill Bits Editorial Review
These grinding bits are versatile and can be used for a variety of purposes. They work well with a variable speed drill, but one reviewer mentioned they may be too powerful for some tasks. Another reviewer suggested they are not the highest quality but are a good value for the price. Some reviewers noted that they did not last very long, while others found them to be excellent and just what they needed. One reviewer had an issue with the cone grinder breaking a spark plug, making the grinding wheel unusable. Overall, the reviews are mixed but mostly positive, with some noting the need for a scrubber instead of a grinder.
