HEX adapter M22 110mm for crown heads – Professional adapter for core drills
Are you looking for a reliable, stable and affordable solution for using your hole saws or core drills on standard drills? The HEX adapter M22 110mm for core bits (SKU: AHEX2) is a premium interface that enables a fast, safe and extremely precise connection between your power tool and the core bit. With this robust adapter, you will optimize your work, increase productivity and achieve professional results, regardless of whether you are an experienced craftsman or a demanding DIYer taking on home renovations.
This high-quality 110 mm hexagonal (HEX) adapter is designed to withstand high loads and torque when drilling into the most demanding construction materials such as brick, concrete and other masonry. The M22 thread ensures a perfect fit with crown heads, while the well-thought-out hexagonal clamping effectively prevents the adapter from slipping in the chuck of your drill. Invest in a tool that provides maximum stability, work safety and an extremely long service life.

Why choose HEX adapter M22 110mm? (Key advantages and benefits)
When working with core drills and heavy crown heads, stability is crucial for your safety and project accuracy. Any shaking, wobble or slippage can damage the workpiece, ruin the expensive crown head or even damage the drill chuck itself. Our professional M22 HEX adapter offers the following key benefits:

Universal Compatibility: The hexagonal handle (HEX) is designed for direct use with regular electric or cordless drills and screwdrivers. You no longer need specialized and heavy SDS machines to work with core bits.
Standard M22 thread: Allows for safe, solid and tight screwing of most standard crown heads and core drills currently available on the market.
Optimal length 110 mm: The extended reach (extensibility up to 110 mm) allows you to drill deeper holes through thicker walls and significantly easier access to hard-to-reach places or corners.
Anti-Slip: The hexagonal shape of the chuck (size 8x110) ensures maximum grip. The adapter will not spin idle inside your drill chuck during heavy drilling, preventing tool wear.
Exceptional value for money: For just €9.99 you get a durable, reliable and professional piece of equipment that will immediately expand the usefulness and versatility of your existing power tools.

How to use the M22 HEX adapter correctly and safely?
Using this adapter is extremely simple and quick, but to achieve the best results and a long tool life, it requires following basic safety and technical steps:

Screwing the crown head: Screw the crown head with the appropriate M22 internal thread onto the male thread of the adapter by hand. Before screwing, make sure that the thread is completely clean, free of dust, sand or metal particles.
To mount in a drill: Insert the hexagonal part of the adapter (8 mm chuck size) deep into the chuck of your drill or screwdriver. Tighten the chuck firmly (we recommend using a chuck wrench if your drill does not use a keyless chuck).
Drilling: Start drilling at lower speeds to ensure a stable and precise start without slipping. Once you have reached the desired depth of the starting groove, adjust the speed and pressure to the material (concrete, brick, plaster) you are drilling.

Using this adapter will save you time and effort, while protecting your equipment from excessive wear and tear. The robust design makes the adapter an indispensable tool in every workshop or construction site.

Frequently Asked Questions (FAQ)
What types of drills is this HEX adapter suitable for?
This adapter has an 8 mm hexagonal (HEX) shank, which means it is perfectly suitable for all common electric and cordless drills and more powerful screwdrivers with a standard three-jaw chuck. The adapter is not intended for direct use in SDS-plus or SDS-max chuck systems without the appropriate adapter heads.
What kind of thread does the adapter have and what crown heads can I fit on it?
The adapter is equipped with a standard M22 male thread. You can quickly and easily mount any core bit or core drill bit that has a corresponding M22 female thread. This is one of the most widespread and established standards for core drill bits for concrete, brick and other building materials.
Does the package also include a centering drill or core bit?
No, this product only includes a standalone 110mm M22 HEX adapter (SKU: AHEX2). Pilot drills, guides and core bits of various diameters are sold separately, allowing you to build your own kit based on your specific needs and drilling diameters.
