- Cleaning concrete surfaces
- Masons and restoration crews working with angle grinders or tuck pointers

Cutting a clean mortar channel
Tuck pointing means grinding out old mortar so fresh mortar can be packed in. The MK-299DT has a .250 width and a 10 mm segment height, which gives you a channel sized for joint work and enough rim to last through repeated passes. If you need a wider channel, MK also offers a .375 width on the 4-1/2 inch size.
Arbor fit
Every MK-299DT size uses a 7/8-inch to 5/8-inch arbor, which fits most angle grinders. Check your tool before ordering.
