• Highlight: The MK Diamond MK-404DT is a 4-1/2" supreme-grade tuck-point blade for masonry — the segmented rim removes mortar from joint lines without chipping the surrounding brick or block face.
• Best For: Masonry restoration contractors and brick repair specialists grinding out failed joints before repointing on residential and commercial brick.
• Expert Note: The 4-1/2" diameter fits standard angle grinders; tuck-point blades cut wider than abrasive discs to clear the joint in fewer passes — run dry with dust collection per OSHA silica rules.
