Tuck point blades are used to clear mortar joints and to prep masonry surfaces. When picking a diamond blade for this type of work, you have two main choices, a tuck point blue blaster and a sandwich diamond blade.
The most common choice is the Blue Blaster Tuck Point Blade. This is a super premium blade with high diamond content. It has .250 rim thickness. It is extremely aggressive and has strong blade life. The speed is decent but slower than the sandwich blade options.The lack of speed in comparison is the only draw back to this blade.
The other popular option is the sandwich tuck point blade. This is basically two general purpose blades stacked on top of each other. This is a faster cutting option and in some cases, is even more aggressive than the blue blaster. Sandwich blades are medium quality level, although you can get a laser welded option, but the price jumps up pretty high. Diamond blade life is a little short on this option, but speed is the main benefit.
Overall, if you want to buzz through a job and get a smooth fast cut, go with the sandwich option and maybe consider upgrading to the premium version. If you want an aggressive strong cut, go with the blue blaster. If I had to choose, I would do the sandwich.
