Frequently Asked Questions
What is this HM lathe tool with replaceable inserts used for?
It is used with metal lathes for productive machining for the operations indicated in the product title.
The choice of the specific model depends on shank size (8, 10, 12, 16, 20 mm), compatibility with lathes with tool holders of the indicated size, and replaceable HM inserts.
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 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 workable 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 tools should be sharpened regularly to maintain a clean cut. The frequency depends on the intensity of use and the material being processed.
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 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.
