Frequently asked questions
What is this impact number and letter set used for?
It is used for manual marking of metal parts with a hammer blow for the operations indicated in the product title.
The choice of the specific model depends on the number of pieces (38 pcs: letters A-Z + numbers 0-8). autonomous use with a hammer on steel or alloys.
What steel are they made of?
Bernardo lathe tools 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 with a shorter useful life, 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 machining with gouges, flat chisels, scrapers and parting blades.
Do they need to be sharpened periodically?
Yes, lathe tools must be sharpened regularly to maintain a clean cut. The frequency depends on the intensity of use and the material being worked.
For HSS blades, sharpening is recommended every 8-15 hours of actual work. Krollit supplies dedicated Bernardo sharpeners (BSG, DG series) to maintain the correct cutting edge angle.
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). Dry storage, away from heat sources.
