Bernardo support table for NTS 200 / 250 Pro / 250 Pro Vario
The support table allows precise sharpening of small workpieces: drill bits, files, chisels, milling cutters, and metal components. The support holds the workpiece in a fixed position relative to the grinding wheel, reducing vibrations and ensuring uniform results.
Unlike freehand sharpening, the support table offers stability and control. This is essential when workpieces are small and difficult to hold, when profile uniformity is required, or when safety is a priority (hands away from the grinding wheel).
The support surface is angle-adjustable, adapting to various blade profiles and components. Its compatibility with three NTS models makes it a versatile accessory for workshops and laboratories that work with various tools.

Frequently Asked Questions
What types of workpieces can I sharpen with the table?
Drill bits, chisels, milling cutters, files, small metal parts (approximately < 100 mm). The support is versatile but not suitable for very small workpieces (< 10 mm) where control becomes critical.
What sharpening angle does the table maintain?
The angle is adjustable as needed. It is not a fixed value like the axe jig. Manual adjustment allows it to adapt to different tool profiles: drill bits (120°), chisels (30-35°), milling cutters (variable).
Is the support table safe for frequent sharpening?
Yes, the support significantly reduces risks compared to freehand sharpening. Hands remain away from the grinding wheel and the workpiece is stable. Always follow Bernardo instructions and wear protective gear.
Can I use it to sharpen drill bits?
Yes, it is one of the main applications. The table keeps the drill bit aligned with the grinding wheel, ensuring a concentric and well-sharpened tip.
How do I maintain the table?
Regular cleaning of metal residues and dust. Occasionally, check the angle adjustment. Minimal lubrication (in case of movable joints). It does not require periodic maintenance like grinding wheels.
How much space does the table occupy on the lathe support?
The table is compact and occupies limited space. Exact dimensions are not declared by the manufacturer; contact Bernardo for specific dimensions. In general, it is compatible with other NTS accessories without space conflicts.
