Best Tuck Point Diamond Blades for Mortar Joint Removal
The best tuck point diamond blade depends on the mortar joint width and your tool’s arbor. For a 1/4-inch cut, consider the EDiamondTools 1/4-inch blade or the DEWALT DW4740; for a wider 3/8-inch cut, compare the EDiamondTools and WENHUALI options. The WENHUALI 1/4-inch model is suited to buyers who also want listed wet-or-dry use for masonry and grout work. Check your grinder’s specifications and the blade’s listed arbor before buying.
| Blade | Listed Segment Width | Best For |
|---|---|---|
| EDiamondTools single blade | 1/4 inch | Medium-to-hard mortar joints |
| EDiamondTools wider blade | 3/8 inch | Medium-to-hard joints needing a wider cut |
| WENHUALI precision blade | 1/4 inch | Masonry, grout, and wet-or-dry use |
| DEWALT DW4740 | 1/4 inch | A straightforward 4.5-inch blade option |
| WENHUALI wider blade | 3/8 inch | Wider mortar and masonry cuts |
EDiamondTools 1/4-Inch Single Blade
This 4.5-inch EDiamondTools blade is designed for medium-to-hard mortar joints. Its 1/4-inch segment width makes it a narrower-cut option than the listed 3/8-inch blades. The product description identifies it as a single-blade style with a solid tip.
Best for: Buyers removing mortar who need a 1/4-inch cut and whose tool matches the listed nonthreaded 7/8-to-5/8-inch arbor specification. It was selected for its specific mortar-joint focus and clearly stated segment width. Limitation: The listed arbor sizing is unusual; confirm the fit with your tool before purchase.
EDiamondTools 3/8-Inch Single Blade
This 4.5-inch blade shares the listed medium-to-hard mortar-joint application and single-blade construction of the 1/4-inch model, but has a 3/8-inch segment width. That makes it the wider-cut choice between the two EDiamondTools options.
Best for: Buyers whose mortar-removal task calls for a wider cut and whose grinder matches the listed nonthreaded 7/8-to-5/8-inch arbor specification. The clearly stated width makes it easier to compare against the narrower option. Limitation: A wider segment may not suit a joint that requires a narrower cut, so assess the joint before choosing.
WENHUALI 1/4-Inch Precision Blade
This 4.5-inch blade has a 1/4-inch segment thickness and a listed 7/8-inch arbor. The product description names concrete, brick, and masonry work, plus mortar and tile-grout removal. It also states that the blade works wet or dry and has high-density diamond segments.
Best for: Buyers seeking a 1/4-inch blade for several listed masonry and grout tasks, including wet-or-dry use. It was selected for its stated applications and specific arbor size. Limitation: The description does not specify a particular mortar hardness range; check whether its stated use suits your job.
DEWALT DW4740 1/4-Inch Blade
The DEWALT DW4740 is listed as a 4.5-by-0.250-inch tuck point blade. Its product details also describe it as easy to use, but provide limited information about applications, arbor fit, or cutting conditions.
Best for: Buyers who want a named 4.5-inch blade with a stated 1/4-inch dimension. It was selected as a direct comparison with the other narrow-width options. Limitation: The available product details do not clarify arbor dimensions or wet-versus-dry use, so verify those points before purchase.
WENHUALI 3/8-Inch Blade
This WENHUALI blade is 4.5 inches, has a 3/8-inch segment thickness, and lists a 7/8-inch arbor. Its stated uses include concrete, brick, masonry, mortar removal, tile grout, and cutting wall grooves. The description says it works wet or dry and uses high-density diamond segments.
Best for: Buyers needing a wider cut for the listed masonry or grout work and a blade with a specified 7/8-inch arbor. Limitation: Its 3/8-inch segment is wider than the 1/4-inch options, so it may not fit a narrower joint-removal plan.
Buying Guide: How To Choose A Tuck Point Blade
Which segment width should you choose?
Compare the blade width with the mortar joint and the amount of material you need to remove. The products here list either 1/4-inch or 3/8-inch segment widths. A 1/4-inch option is narrower; a 3/8-inch option makes a wider cut. Do not assume either width is right for every joint. Measure the work area and choose a blade that suits the intended cut.
Will the blade fit your grinder?
Check the grinder’s supported blade diameter, arbor, and operating instructions before ordering. These products are listed as 4.5-inch blades, but their arbor details vary: the WENHUALI models specify a 7/8-inch arbor, while the EDiamondTools listings describe a nonthreaded 7/8-to-5/8-inch size. The DEWALT details supplied here do not state an arbor size. Do not rely on diameter alone to confirm fit.
What work will you do?
For mortar joints, prioritize a product that explicitly lists mortar removal. For broader tasks, the WENHUALI descriptions also name concrete, brick, masonry, or tile grout. The 1/4-inch WENHUALI model and both EDiamondTools options state distinct features that help compare them: wet-or-dry use for the former and medium-to-hard joint use for the latter.
What safety checks matter?
Use the blade only with a compatible tool and follow the tool and blade manufacturers’ instructions. Inspect the blade before use, secure the workpiece, and use appropriate protective equipment and dust control for masonry cutting. Confirm whether the task and equipment allow wet or dry operation; only the WENHUALI descriptions here explicitly state both modes.
Frequently Asked Questions
What is a tuck point diamond blade used for?
It is used to cut mortar from masonry joints for removal and repair. Some listed blades also specify uses such as brick, concrete, masonry, or tile-grout removal.
Is a 1/4-inch or 3/8-inch blade better?
Neither is universally better. Choose based on the cut width required for the joint and the product’s stated applications.
Can these blades fit any 4.5-inch angle grinder?
No. A 4.5-inch diameter alone does not confirm compatibility. Check arbor size and the grinder manufacturer’s specifications.
Which listed blades specify wet-or-dry use?
Both WENHUALI product descriptions state wet-or-dry use. The other product details provided do not specify this capability.
What does the arbor measurement tell me?
The arbor measurement describes the mounting opening or fit needed to attach a blade to a tool. Compare it with your grinder’s requirements before buying.
