What are the different types of cutting or grinding section? |
||||
Fluted cutting section |
||||
 |
On a fluted mortar rake, the flutes act as blades when the tool is rotating, cutting away at the mortar. The bottom of the flutes open up and this is where the mortar moves away from the cutting part of the tool. | |||
Gritted section |
||||
 |
On a gritted mortar rake, the gritted section rotates quickly through the mortar, grinding it away. | |||
 |
Special featuresOn a mortar rake designed for an SDS plus drill, the tip of the rake is uneven, so as to grind straight into the mortar more easily. The holes in the grinding section of the tool carry mortar dust and debris away from the working area, through the mortar rake and down the outlet pipe. |
|||
 |
Some mortar rakes have a pointed tip. These allow the tool to work straight into the mortar without a pre-drilled hole. | |||
Removable cutting/grinding sections |
||||
 |
Some mortar rakes can be bought as seperate components. With these types, the cutting/grinding section of the mortar rake can be taken out of the collet nut and turned around so you can use both ends.
Being able to purchase the cutting/grinding section of these mortar rakes separately means you don’t have to invest in the whole tool again. |
|||
Longer or shorter cutting/grinding sections |
||||
 |
This particular mortar rake does not have a terribly long grinding section and so would be unsuitable for single brick removal. | |||
 |
In contrast, this mortar rake has a longer grinding section that is ideal for reaching the back of a brick joint, making it easy to take the brick out whole, once all the mortar surrounding it has been removed. | |||
