Short Knife Support Bernardo NTS 200 / NTS 250 Pro / NTS 250 Pro Vario
The short knife support is specifically designed by Bernardo engineers to hold short blades and knives stably during grinding on a sharpener. Unlike a general vise, this support uses the machine's anchoring points and geometries, ensuring precise centering.
The support is compatible with three models in the NTS series:
- NTS 200 (entry-level, single-phase wet/dry grinder, 230 V)
- NTS 250 Pro (mid-range, three-phase 400 V)
- NTS 250 Pro Vario (variant with adjustable speed, three-phase 400 V)
Who chooses this accessory
Krollit customers who work with lathes, milling machines, grinders, and cutlery often need to finish short details (carpentry knives, straight blades, milling cutter blades) on a grinder, where a traditional vise does not guarantee the required geometry and centering. The Bernardo support allows this work to be done safely without improvised configurations. In the Krollit catalog, it represents the official solution where other generic accessories do not achieve the necessary precision.
Who is the Bernardo 05-20606 support suitable for?
| Profile |
Suitable? |
Reason |
| Advanced hobbyist / wood craftsman |
Adequate |
If they already own a Bernardo NTS and occasionally work on short details (milling cutter blades, carving knives), it is a practical upgrade. Use every 2-4 weeks does not justify isolated machine purchase. |
| Small workshop (1-5 operators, cutlery/carpentry) |
Ideal |
Daily operation on short details (knives, milling cutter blades, drills). Compatible with existing NTS machines. Positive ROI in 2-3 months with frequent use. |
| Continuous 24/7 production / industrial |
Not indicated |
The NTS series is not sized for continuous cycles. For series production of short details, consider dedicated industrial grinders (other brands, greater power). |
Not suitable for: Machining long or complex objects (the support is designed exclusively for short details <100 mm). Operators who do not own a Bernardo NTS (machine purchase is a prerequisite). Environments with excessive vibration (unstable foundations) that compromise centering.

Frequently asked questions
Is the 05-20606 support compatible with my NTS 250 Pro?
Yes. The Bernardo item 05-20606 is specifically designed for NTS 200, NTS 250 Pro, and NTS 250 Pro Vario. Assembly is simple and takes 3-5 minutes without special tools.
What diameters and lengths of knives can I work with this support?
The manufacturer does not state specific diameter and length ranges on the product page. It is recommended to contact Krollit technical assistance to clarify the exact capacity based on your type of knife or blade.
Can I also use the support on other non-Bernardo grinders?
No. The support has been calculated for the geometry of the nose and clamping systems of Bernardo NTS. Adaptation to other brands would require structural modifications and would lose CE approval.
How is the support cleaned and maintained?
Dust with a dry brush after each work session. Light lubrication of the sliding guides every 40 hours of work with light oil (e.g., 3-in-1). Avoid direct water if it is not certified as water-repellent.
Does Bernardo sell spare parts if the support wears out?
Yes. Internal springs, sliding guides, and other wear components are available as original Bernardo parts.
What warranty does Bernardo offer on this support?
24-month warranty from the date of purchase against manufacturing defects. Excludes normal wear and tear from use, damage from poor maintenance, unauthorized modifications, and environmental deterioration (excessive humidity).
Can I order the support separately from the machine, or is it a mandatory bundle?
Yes, the support can be ordered separately. It is sold as a single accessory. Useful for customers who already own an NTS and want to expand their range of operations.
