Frequently asked questions
What is this internal/external grooving lathe tool used for?
It is used with metal lathes for precision grooving for the operations indicated in the product title.
The choice of the specific model depends on the type (internal or external) and shank dimensions, compatible with lathes with standard tool holders.
What steel are they made of?
Bernardo lathe blades are made of HSS (High Speed Steel) or Carbon Steel depending on the model indicated in the title.
HSS withstands temperatures up to 600 °C and is suitable for most woods and materials. Carbon Steel is more economical but has a shorter lifespan, suitable for hobby use.
How many pieces does the set contain?
The number of pieces is indicated in the title (e.g., "5 pieces", "6 pieces", "8 pieces"). Larger sets cover a wider range of machinable profiles.
Starter sets (4-5 pieces) for beginners, professional sets (6-8 pieces) for complete operations with gouges, flat chisels, scrapers, and parting blades.
Do they need to be sharpened periodically?
Yes, lathe blades must be sharpened regularly to maintain a clean cut. The frequency depends on the intensity of use and the material being machined.
For HSS blades, sharpening is recommended every 8-15 hours of actual work. Krollit provides dedicated Bernardo sharpeners (BSG, DG series) to maintain the correct cutting edge angle.
How should they be stored correctly?
Store in a dedicated drawer or mat with individual protection, lightly oiled to prevent oxidation. Avoid contact between cutting edges.
Surface oxidation reduces cutting quality and accelerates wear. Clean after each use and apply a protective film (machine oil or WD-40). Store in a dry place, away from heat sources.
