Adapter sds MAX for crown heads 450mm

SDS MAX adapter for core bits 450mm - Professional extension for demanding deep drilling

Are you looking for a reliable, robust and professional solution for drilling extremely deep holes in the hardest construction materials? The 450 mm SDS MAX adapter for core bits is an indispensable tool for builders, plumbers, electricians, air conditioner installers and demanding DIYers. This premium extension allows you to easily, safely and effectively increase the reach of your core saws, opening the door to projects that were previously completely unattainable with standard equipment.

With an exceptional length of 450 mm and a universal standard M22 thread, this adapter is perfectly optimized for heavy-duty work in the most demanding materials such as concrete, brick and stone. Forget about drill bits that are too short, makeshift solutions and inefficient work on the construction site. With this professional SDS MAX adapter, you will make every breakthrough significantly faster, more precisely, safer and with minimal effort.

Key benefits of using the SDS MAX 450mm adapter

• Exceptional reach (450 mm): This high-performance adapter is used to extend core cutters to a working length of 450 mm. It is an essential tool wherever deep holes and penetrations through thick walls, concrete slabs, beams or solid foundations need to be made.
• Perfect precision with a pilot drill: The adapter is equipped with a high-quality pilot drill bit, which ensures stable and precise centering right from the start of drilling. This effectively prevents dangerous core slippage, vibrations and unwanted damage to the work surface.
• Universal thread M22: The standard M22 connection thread allows for extremely quick, easy and safe installation of most standard crown heads (core cutters) available on the market.
• Professional SDS MAX chuck: Designed specifically for use with larger and extremely powerful rotary hammers with SDS MAX chuck. This ensures maximum and optimal power transfer from the machine to the core bit head without any losses or slippage in the machine head.

Why choose this adapter for your next construction projects?

When carrying out installation work, laying drainage and water pipes, installing ventilation systems or routing electrical cables, contractors are constantly faced with walls and partitions that far exceed the standard length of conventional core drills. The SDS MAX adapter for core drill heads 450mm offers a cost-effective and extremely practical solution to this problem. Instead of buying expensive, specialized and extremely long core drills, you simply and quickly extend your existing core drill head with an M22 thread.

Thanks to the included pilot drill bit, starting drilling is extremely easy and safe. The pilot drill bit first reliably makes a pilot hole, which then holds the entire heavy core bit and long adapter assembly in a perfectly straight line. When the core bit cuts into the material, the pilot drill bit ensures that the entire drilling operation is smooth, stable and without unnecessary, dangerous vibrations that could damage your power tool or the material.

Frequently Asked Questions (FAQ)

Which building materials is this adapter best suited for?

The 450 mm long SDS MAX adapter is intended for use with core bits for drilling into hard building materials such as concrete, reinforced concrete, classic brick, silicate brick, clinker, natural stone and other building blocks. The adapter itself ensures reliable transmission of torque and impact power, while the final drilling performance and speed depend on the quality and sharpness of the core bit used.

Is the centering pilot drill already included in the package?

Yes, the adapter is delivered in a set that already includes a pilot centering drill. The pilot drill allows you to center the drill at the desired drilling point with extreme precision and effectively prevents unwanted movement or slipping of the drill bit upon first contact with the material.

What kind of thread does this adapter use to mount hole saws?

This adapter uses the standard M22 thread, which is considered the most widespread and used standard for hole saws, core cutters and core drills on the market. Please check whether your core head supports the M22 connection thread before purchasing.
