How to choose the right modular breakthrough drill bit
When choosing a modular breakthrough drill bit, it is important to select the correct milling head diameter and suitable adapter length according to the required penetration depth. Compared to complete breakthrough drill bits, this system allows you to combine multiple drilling diameters simply by changing the working head, without the need to purchase a complete drill bit for every variant.
The range includes two SDS-max adapter lengths, allowing the setup to be adapted for standard and deeper structural penetrations. This makes the selection process simpler than with more extensive modular systems.
When choosing a subcategory, 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 individual drilling diameters.
Where and how modular breakthrough drill bits are used in practice
modular breakthrough drill bits are mainly used for construction and installation work where larger penetrations of different diameters and varying drilling depths are required.
Typical applications include:
- penetrations for pipes and waste systems,
- electrical installation routes,
- ventilation systems,
- renovation of older buildings,
- and repeated drilling of multiple diameters under similar conditions.
The advantage of this system is the ability to keep the adapters and only change the core cutter according to current needs. This makes work easier especially where different penetration diameters are used regularly.
How to work with modular breakthrough drill bits
modular breakthrough drill bits are designed for powerful electro-pneumatic hammer drills with the SDS-max system. Before drilling, it is important to correctly assemble the milling head with the adapter and check that the connection is securely tightened.
For deeper penetrations, we recommend:
- regularly removing drilled material from the hole,
- maintaining stable drill bit guidance,
- avoiding excessive pressure on the hammer drill,
- and using a sufficiently powerful machine suitable for the drilling diameter.
The core cutter allow you to assemble a lighter penetration tool compared to more robust modular systems, but it is still necessary to take into account that drilling larger diameters remains a demanding task.
Which types can you continue with?
In this category, you can choose between two basic system components:
By combining a milling head and an adapter, you can create a complete breakthrough drill bit according to the required drilling diameter and depth. The advantage of this system is the possibility of gradual expansion without the need to purchase a separate complete drill bit for every variant.
