Dinamitek: The Complete Guide to Professional Abrasives

To work better, faster and with superior results

Abrasives are essential tools in every mechanical process: from cutting to deburring, from finishing to surface preparation. Choosing the right abrasive means speeding up the work , reducing consumption , improving the quality of the result and, above all, working safely .

Dinamitek selects only professional brands like 3M – Cubitron II , Scotch-Brite™ , Klingspor, Valex, along with the best tool holders like Bosch and Panasonic . Because the quality of the abrasive is an integral part of the quality of the work.

1. What are abrasives and why are they so important?

An abrasive is a natural or artificial material characterized by:

• high hardness
• low fragility
• crystalline structure

These properties allow for operations such as cutting, sharpening, sanding, deburring, and finishing . The final result depends on three factors:

• abrasive material (aluminum oxide, zirconium, PSG ceramic, etc.)
• support (paper, canvas, disc, fiber…)
• working parameters (speed, pressure, angle, tool)
  
  
  

2. The main fields of application of abrasives

Professional abrasives are used on:

• steel and stainless steel
• soft metals
• stone and mineral materials
• glass and plastic
• wood and derivatives
• paints and coatings

Stainless steel: where abrasives make the difference

Stainless steel becomes “precious” thanks to the final grinding , which increases:

• corrosion resistance
• the aesthetic shine
• the uniformity of the surface

The quality of grinding depends on the tool, working parameters and characteristics of the abrasive.

3. Abrasive families: which ones to choose and when

3.1 Cutting discs

Used to separate material. Available in two forms:

• T41 – flat : fast and deep cutting
• T42 – depressed center : controlled cut and greater visibility

Applications: pipes, profiles, sheet metal, steel, stainless steel, hard metals.

3.2 Grinding discs

Designed to remove material , not cut.

• T27 – depressed center : heavy deburring, weld beads, chamfers
• T28 – flat : flat surfaces

3.3 Flap discs

They combine abrasive blades on a fibre backing.

• T27 : deburring + finishing
• T29 : conical slats, more aggressive

3.4 Fiber discs

Abrasives on vulcanized fiber, for use with a backing pad . Ideal for:

• weld removal
• heavy smudges
• machining on stainless steel and hard steels
• surface preparation

3.5 Tapes, sheets and rolls

Used for belt sanders, orbital sanders and for finishing on wood, plastic and paint.

4. Why choose professional abrasives

A quality abrasive guarantees:

• faster cutting
• reduced vibrations
• lower consumption
• greater security
• superior finish

5. Dinamitek partners: certified quality

Dinamitek selects only professional brands such as 3M, Scotch-Brite™, Klingspor, Valex, Bosch, Panasonic, and LTF. These brands guarantee high-performance abrasives, superior durability, and certified safety.

6. How to choose the right abrasive

The choice depends on:

• material to be worked
• type of processing (cutting, deburring, finishing)
• tool used
• grain
• mineral
• disc shape
