Metal Bond Diamond-How to Choose the Correct Bond

Maybe you may have no idea in what I am talking about?

What is a bond?

This may be one of the questions when buying metal bond diamonds you may have to think about.

A bond is basically the mix of metals,or resins that surrounds and exposes the diamond as you are cutting.The bond is chosen based on the hardness of your concrete,and can be divided into three kinds: soft bond,medium bond and hard bond.

Soft bond is ideal for hard materials as the soft metal wears away always exposing a layer of diamonds.If the metal bond is too hard,the diamond becomes trapped in the surface i.e.a hard bond on hard burnished concrete-this is called glazing.If the metal bond is too soft it wears away too quickly i.e. a soft diamond on soft abrasive concrete such as new/green concrete.

Medium bond is the most popular bond.It can be used on both hard and soft materials but will wear more quickly on soft materials and not cut as well on hard materials.It is effective on the widest variety of floors.A general rule of thumb is that if you (or your customer) are not sure the hardness of the floor and not able to test it,start with a medium bond diamond.

Hard bond is resistant to soft abrasive material such as asphalt,soft/green concrete,and rain damage concrete.Hard bond diamonds can be effective because of the soft properties of the adhesive/mastic on the floor.

Choosing the wrong bond may cost you lots of time and money. The best thing you can do is do a concrete hardness testing kit first then you will know exactly what you want.
