Frequently asked questions
What is this drill bit set used for?
It is used with drilling and dimensional checks for the operations indicated in the product title.
The choice of the specific model depends on the number of pieces (41, 118, 170 pcs) and type (twist, measuring). Compatible with drills and inspection applications.
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 has a shorter service 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 workable profiles.
Starter sets (4-5 pieces) for beginners, professional sets (6-8 pieces) for complete work with gouges, flat chisels, scrapers, and parting tools.
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 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.
