Tuck Point Diamond Blades: The Engineering & B2B Sourcing Guide

A single tuck point blade uses a wide single segment (typically .250" or .375" thick) welded to a heavy-gauge steel core. It is economical and suitable for standard joint cleaning. A double blade utilizes two stacked blades with or without a spacer to clean out wider joints in a single pass. A sandwich tuck point blade is an advanced design featuring two razor-sharp outer diamond cutting segments sandwiching an abrasive, softer center layer. While the diamond borders cleanly track the brick edges without chipping, the abrasive inner core aggressively breaks and ejects the mortar matrix. Sandwich blades typically cut twice as fast as single wide blades in hard mortar.

Mortar raking produces a highly abrasive granular slurry of silica sand. This slurry circulates between the joint walls and the steel blade core, wearing away the steel right beneath the diamond segment (undercutting), which leads to fatal segment loss. Diamond Vantage combats this by engineering deep-drop segments, inset carbide wear plates, and alternating deep protection gullets on the core. This diverts abrasive dust away from the weld zone and extends the safe operational life of the blade core.

All Diamond Vantage tuck point blades are 100% laser welded, allowing them to withstand the extreme thermal stresses of both dry and wet cutting. However, because wet tuck pointing on vertical brick facades causes hazardous slurry staining and water penetration into building envelopes, over 95% of tuck pointing is performed dry. Dry operation requires pairing the blade with an OSHA Table 1 compliant point-of-origin dust extraction shroud and a certified HEPA vacuum rated at 25 CFM per inch of blade diameter.

Our standard production lines feature blade diameters of 4", 4.5", 5", and 7". For handheld 4.5" and 5" small angle grinders, we provide either standard 7/8" non-threaded arbors with 5/8" reducing bushings or factory installed 5/8"-11 quick-spin threaded steel hubs. For large 7" walk-behind or high-amperage handheld saws, we supply standard 7/8", 1", or DM-20mm custom arbors dynamically balanced for zero runout.

Because we are a true manufacturer, we offer turnkey OEM programs for wholesale distributors, rental chains, and professional masonry suppliers. We handle high-resolution permanent laser engraving of your company brand, custom blade paint colors, customized segment formulas matched to your regional market mortar profiles, custom barcode packaging, and scheduled batch delivery from our West and East Coast distribution warehouses.
