Drill bits, augers & hole saws

Frequently asked questions — Drill bits, augers & hole saws

• In which cases should a hole saw be preferred over a conventional drill bit?

  The use of hole saws is recommended when drilling operations require the production of large-diameter cuts. Unlike solid drill bits, which must remove the entire volume of material, hole saws act on the periphery of the hole, which results in reduced energy consumption during machining. This technical choice is particularly relevant for optimising drilling performance on large diameters while preserving the efficiency of the tooling used.
• Which standard ensures the compliance of short twist drills for metals?

  For work on metals, MecaIndus offers short twist drills compliant with the DIN 338 standard. This standardisation guarantees a rigorously defined cutting geometry, providing the rigidity needed to meet the technical requirements of industrial machining. Compliance with this standard is essential to ensure the precision and reliability of drilling when working on metals, in line with the specifications of partner manufacturers such as HELLER, DIAGER, MILWAUKEE, ERKO, LEMAN, FISCH, PHANTOM and INT. TOOLS.
• How do you choose the right abrasive for a grinding operation in complete safety?

  Selecting an abrasive tool for grinding relies on the analysis of the working environment and compatibility with the tooling, whether portable or stationary. To ensure the integrity of discs and grinding wheels during use, MecaIndus offers references that strictly comply with the EN 12413 standard. This standard governs the safety requirements relating to bonded abrasive products, thereby ensuring implementation in line with the technical standards required in a professional context for surface treatment and deburring operations.
• Which parameters should I take into account to select the right drilling tool?

  Selecting the appropriate drilling tool requires a precise analysis of several technical parameters. It is essential to consider the desired drilling diameter, the nature of the material to be worked, whether metals or construction materials, as well as the required machining depth. Furthermore, defining the permissible cutting speeds is decisive in ensuring machining efficiency. All these factors make it possible to determine whether the application requires the use of drill bits, augers or hole saws.
