Key benefits of using SDS-plus to HEX adapter
Using a professional adapter brings many benefits that directly translate into increased productivity and reduced fatigue at work. Here are the main reasons why this adapter is a must-have for every craftsman:

Exceptional versatility and adaptability: Allows you to transform your rotary hammer or drill with standard SDS-plus chuck into a powerful screwdriver in seconds. Ideal for demanding screwdriving in wood, metal, plaster or concrete using the appropriate screwdriver bits.
Strong integrated magnetic grip: The built-in, very strong magnet ensures that the screwdriver bits remain firmly and stably in place. This prevents the bits from falling out while working, which is crucial when working overhead, at height or in hard-to-reach and tight spaces.
Superior durability and premium materials: The combination of high-quality stainless steel and durable chrome-vanadium steel (Cr-V) ensures extremely high resistance to mechanical wear, corrosion and strong torsional loads.
Time efficiency on the jobsite: Quick and easy bit changes without the use of any additional tools or wrenches save you valuable time and allow for a smooth workflow.

Technical features and specifications of the BITU8 model
When choosing a professional tool, the quality of the materials used and the precision of the workmanship are key. This adapter was designed with longevity, stability and demanding daily use in mind. Below are the exact technical specifications of the product:

Chuck (input): Standard SDS-plus chuck, suitable for most rotary hammers on the market.
Output (reception): Standard 1/4" (hexagonal - HEX) reception for secure installation of screwdriver bits and bits.
Total length: 85 mm – an optimal length that provides excellent reach into deeper holes while maintaining maximum stability and minimal vibration during work.
Material of manufacture: High-quality stainless steel combined with proven chrome-vanadium steel (Cr.V.) to achieve maximum strength and torque.
Magnet: Built-in extremely strong permanent magnet to securely hold all types of metal bits.

Why choose the BITU8 model?
You will find many different adapters on the market, but the SDS plus magnetic extension 85mm to HEX (SKU: BITU8) stands out with its extremely robust construction made of stainless steel and Cr.V. alloy. This thoughtful combination of materials effectively prevents rust and ensures that the adapter will not deform or crack under the influence of the forces generated when working with more powerful machines. The strong magnet in the chuck head ensures that you will complete every job without unnecessary interruptions due to constantly falling bits on the floor.
Important note for safe and long-lasting use: Although the adapter is extremely strong and made of high-quality Cr.V. steel, it is intended for rotary use only (screwdriving and drilling without impact). When using this adapter on your SDS-plus machine, always turn off the impact (hammer) function and switch to rotary mode only. This will prevent damage to the adapter, screw bits or the machine head itself.
Frequently Asked Questions and Answers (FAQ)
Can I use this adapter on all brands of rotary hammers?
Yes, the adapter is equipped with a standard SDS-plus chuck. This means that it is fully compatible with all rotary hammers and machines from all established brands on the market that use the established SDS-plus chuck system.
Is the adapter suitable for impact operation (drilling and impact drilling)?
No. This adapter is intended for screwdriving and drilling with rotation only (no impact). Before starting work, be sure to switch your SDS-plus tool to non-impact mode (rotation only). Impact force could permanently damage the adapter, magnet or bit.
How strong is the magnet in the adapter and does it hold longer bits?
The adapter contains a very strong integrated magnet, which is specially designed to hold standard screwdriver bits securely and firmly in place. It effectively prevents the bits from falling out even when subjected to centrifugal forces or when working in a vertical position directly upwards.
