## Description

Cluster Diamond Brazing Technology (CDB) CDB Procss is a new concept and invented technology of diamond segment production. The purpose of CDB product is to make high level grinding & coating removal and to make it possible, diamond particles must be strongly griped through the molecular sintering method. And also diamond concentratioln shoud be suitably designed with metal powser for high performance because high concentration is not always good for its ability. CDB newest technology has these 2 strengths, strong grip power and suitable concentration and it can make optimised grinding and removing performance. Arbor Hole : 7/8" - 5/8" (4") Arbor Hole : 7/8" (5" & 7") Grit size : Coarse #35 Diamond Grip : Molecular Bonding Material : Diamond Color : Black Matt Available in 3 different sizes, 4" / 5" / 7"

Review: It handled me sanding down 24 concrete pillars to level. - I don't leave many reviews but I saw other people having problems with other discs and thought I'd share my experience. I had 24 concrete pillars I need to smooth and sand down to level. This disc did a great job of all the work needed. I sanded down all 24 of them and by the end it was still able to cut material down. So 5 stars for me.
Review: awesome go-to cupwheel - I've ordered this wheel three times now and it's awesome. With skill it can leave a relatively scratch-free honed finish or hog out concrete (or remove coatings) fairly aggressively. The numerous edges make it effective and I suspect it has fairly moderate size grit because it doesn't leave rogue diamond scratches as with bargain basement priced wheels. Reasonable cost, too. I keep a couple on hand and is one of the very few diamond tooling that I repeat buy.
