How to choose the right complete breakthrough drill bit
Complete SDS-max breakthrough drill bits are mainly suitable for situations where you need a ready-made solution without assembling individual system components. The main selection criteria are the required drilling diameter, drill bit length, and the power of the hammer drill being used.
Compared to modular systems, these drill bits have a fixed working length and construction. Their advantage is simple and fast use without the need to combine milling heads, adapters, or other accessories.
When choosing a specific drill bit, focus mainly on:
- required hole diameter,
- required drilling depth,
- type of material being drilled,
- power of the SDS-max hammer drill used,
- and frequency of use for larger drilling diameters.
Where and how complete breakthrough drill bits are used in practice
Complete breakthrough drill bits are mainly used for creating deep penetrations in masonry, concrete, and other building structures. Typical applications include installation and construction work where larger diameters and deeper holes are required.
Typical applications include:
- penetrations for pipes and waste systems,
- electrical installation penetrations,
- ventilation system installations,
- renovation of older buildings,
- and drilling deeper holes in solid structures.
Thanks to their solid construction and ready-made design, they are especially suitable for fast deployment on-site without the need to assemble the system before each use.
How to work with complete breakthrough drill bits
Complete breakthrough drill bits are designed for powerful electro-pneumatic hammer drills with the SDS-max system. Drilling larger diameters creates high stress on both the machine and the drill bit itself, so it is important to use a sufficiently powerful hammer drill and avoid excessive pressure during operation.
For deeper penetrations, we recommend:
- regularly removing drilled material from the hole,
- monitoring drill bit alignment within the hole axis,
- avoiding excessive pressure on the drill bit,
- and maintaining a stable working position when drilling larger diameters.
With longer drill bits and larger diameters, it is necessary to take into account the higher tool weight and increased demands on machine performance.
Which types can you continue with?
In this category, you can choose complete SDS-max breakthrough drill bits in various diameters and working lengths.
The individual drill bits differ mainly in:
- drilling diameter,
- working length,
- drill head construction,
- and intended application type.
If you need greater flexibility in lengths or the possibility to combine multiple drilling diameters within one system, the Configurable breakthrough drill bits category or the professional system VARIANT may be a better choice.
