Abrasives & Brushes

Frequently asked questions — Abrasives & Brushes

• How do I choose between an abrasive and a brush for preparing my surfaces?

  The choice between an abrasive and a brush depends essentially on the material to be treated, the geometry of the workpiece and the desired finish. Technicians must assess the grit type and the hardness of the substrate to guide their selection. These tools cover a variety of applications such as deburring, polishing and surface preparation. The brands ABR. HERMES, DRONCO, SIA ABRA., PFERD, DIAM IND., PRODIXAL, SAM and LEMAN offer solutions tailored to these technical requirements.
• What safety precautions apply to the use of bonded discs and grinding wheels?

  Safety in use is a fundamental criterion when implementing these tools. Bonded discs and grinding wheels must be selected and handled in accordance with the requirements of the EN 12413 standard. This standard defines the specific safety parameters for bonded abrasive products. It is necessary to verify that the tool matches the mechanical characteristics of the workpiece in order to guarantee the compliance of the operations performed.
• Should I prioritise abrasives or drill bits for my drilling and cutting work?

  The choice between the abrasives and brushes category and the sub-family of drill bits, twist drills and core drills depends on the technical application targeted. Abrasives are intended for deburring, polishing and surface preparation. For work specifically requiring drill bits for metal, reference should be made to the DIN 338 standard for short twist drills. Matching the tool to the mechanical characteristics of the workpiece makes it possible to optimise the machining process.
• Does the type of machine influence the selection of my abrasive?

  Yes, technicians must take the type of machine used into account when choosing an abrasive. The equipment can range from portable grinders to stationary machines. This technical parameter, combined with the analysis of the material and the geometry of the workpiece, is essential to ensure the effectiveness of the tool. The tools supplied by the brands ABR. HERMES, DRONCO, SIA ABRA., PFERD, DIAM IND., PRODIXAL, SAM and LEMAN meet the various needs associated with these working environments.
