Who uses the 05-20606 and for what
The 05-20606 support is chosen by blacksmiths, knifemakers, carpenters, and small workshop operators who work with short details on a Bernardo NTS grinder and require precise centering without improvised setups. Router bits, woodworking knives, and straight blades are the most frequent use cases among Krollit customers. A traditional vise does not replicate the NTS anchoring geometry: the original Bernardo support maintains manufacturing tolerances and compatibility with other accessories in the series, allowing for quick changes between different workshop configurations.

Who the 05-20606 is for
| Profile |
Compatibility |
Reason |
| Advanced hobbyist / wood craftsman with Bernardo NTS |
Suitable |
Practical upgrade for those who occasionally work short details (router bits, carving knives) every 2–4 weeks; does not justify the isolated purchase of the machine |
| Small workshop (1–5 operators, cutlery or woodworking) |
Suitable |
Daily operation on knives, router bits, and drill bits; compatible with existing NTS; positive ROI in 2–3 months with frequent use |
| 24/7 continuous or industrial production |
Not suitable |
The NTS series is not dimensioned for continuous cycles; for series production of short details, it is advisable to consider dedicated industrial grinders of a different range |
Not suitable for: working on long or complex objects (the support is designed for short details under 100 mm), operators who do not own a Bernardo NTS grinder, environments with excessive vibrations that compromise centering.

Frequently Asked Questions
Is the 05-20606 support compatible with the NTS 250 Pro and the NTS 250 Pro Vario?
Yes. Item 05-20606 is specifically designed for NTS 200, NTS 250 Pro, and NTS 250 Pro Vario. It mounts on the machine head and takes 3–5 minutes without special tools.
The anchoring geometry is common to the entire Bernardo NTS series. No additional adapter is required. To check compatibility with a specific serial number, contact Krollit technical assistance at +39 0825-1494022.
Can I use the 05-20606 on grinders of other brands?
No. The support is calculated for the head geometry and locking systems of the Bernardo NTS series. Adapting it to grinders of other brands would require structural modifications and would result in the loss of CE approval.
Use on machines other than NTS 200, NTS 250 Pro, and NTS 250 Pro Vario is not supported by Bernardo and is not covered by the warranty. For those looking for a support for other grinders, it is advisable to check with Krollit if a dedicated accessory exists for the model in use.
What lengths of knives and blades can I work with this support?
The manufacturer does not declare specific length and diameter ranges on the official technical sheet. The support is designed for short details under 100 mm: woodworking knives, straight blades, and router bits fall into the typical use case.
To check the exact capacity based on the specific type of blade or knife, contact Krollit technical assistance at +39 0825-1494022 before purchasing.
How is the 05-20606 support maintained over time?
Dust with a dry brush after each work session. Light lubrication of the sliding guides every 40 hours with light oil (e.g., 3-in-1). Avoid direct water on the support.
Wear components (internal springs, sliding guides) are available as original Bernardo spare parts with a lead time of 3–5 days from Austria. Krollit manages import into Italy with SDI documentation for B2B customers. The original spare part maintains manufacturing tolerances and compatibility with the NTS machine.
Can I order the 05-20606 separately without also purchasing the grinder?
Yes, the support is sold as a single accessory and can be ordered separately. It is aimed at customers who already own a Bernardo NTS and want to extend the range of possible operations.
For those who do not yet have an NTS grinder, purchasing only the support has no practical use: the attachment is specific to the NTS series and is not adaptable to other machines.
What warranty covers the Bernardo 05-20606 short knife support?
Official Bernardo warranty of 24 months from the date of purchase against manufacturing defects. The warranty excludes normal wear and tear from use, damage from poor maintenance, unauthorized modifications, and deterioration from excessive humidity.
Krollit, as the official Bernardo distributor in Italy since 2007, manages warranty procedures directly in Italian without the customer having to interface with the Austrian headquarters.
