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 cheaper but has a shorter lifespan, suitable for hobby use.
How many pieces are in the set?
The number of pieces is indicated in the title (e.g., "5 pieces," "6 pieces," "8 pieces"). Larger sets cover a wider range of workable profiles.
Starter sets (4-5 pieces) for beginners, professional sets (6-8 pieces) for complete machining with gouges, flat chisels, scrapers, and parting blades.
Do they need to be sharpened periodically?
Yes, lathe blades need to be sharpened regularly to maintain a clean cut. The frequency depends on the intensity of use and the material being worked on.
For HSS blades, sharpening every 8-15 hours of actual work is recommended. Krollit supplies dedicated Bernardo sharpeners (BSG, DG series) to maintain the correct angle of the cutting edges.
How are they 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.
