2m – 4.5m Block Cutting Blades

Block cutting Diamond segments are available for the following natural stone materials;

  • Granite block cutting
  • Granite quarry cutting
  • Sandstone
  • Wonderstone (Pyrophyllite)

Toolgal stock a variety of block segments to suit all different machine types, revolution speeds, diameter and cutting preferential.

   These include;

  • 26mm free cutting
  • 26mm more free cutting
  • 26mm more life
  • 30mm free cutting
  • 30mm more life
  • 15mm quarry cutting (2.5m, 3.5m and 4.5m)

We do provide the service of re-tipping on site or collecting saw blades to be re-tipped in-house.

The process of new and re-tip blades include;

  • Removing of used diamond segment

Great care is being taken in the removing of consumed segments to ensure minimum heating requirements. For new blades this process is not required.

  • Grinding of peripheral of saw blade body

This allows for the removing of any excising brazing materials that may lead to contamination once  the new diamond tips will be married to the saw blade body. Further it will also allow for a clean, smooth, and wider surface area for the new segment to bond to. “Bulleting” of saw blade landing is a common concern, and the grinding process will reduce this phenomenon.

  • Cleaning saw blade surface

The saw blade is surfaced cleaned either chemically or mechanically to ensure the complete removal of lime, rust or other foreign material built-up.

  • Pre-inspection

Prior to re-tipping, all saw blades undergo an inspection process to ensure that the body are  still in good working condition.

Cracks that may occur on saw blades, will be identified and if required be stopped.

  • Re-tipping process

The new diamond segment as per customer requirements are brazed onto saw the  blade body with precision, all segments also undergo a strength and visual inspection to ensure good adhesion between segment and saw blade body.

  • Opening of segments

Saw blades then undergo a opening process where the saw blades are placed on a “opening machine where the peripheral of the blade, thus segments are opened using a grinding process.

  • Tension run-out

All saw blades undergo a final inspection where the tension, run-out and dish of the blades are again checked and adjusted according to European standards. Toolgal uses an one of a kind in South Africa rolling machine to reduce hammering on saw blades, thus extends saw blade life. 

  • Machine alignment

Our trained technicians will also inspect machine and trolley alignment to ensure straight and accurate cutting.
