Frequently asked questions
Which grit should I choose for my work?
K36-K60 for roughing and paint/glue removal; K80-K120 for intermediate sanding; K150-K240 for pre-painting finishing.
K36 grit is too aggressive for sharpening tools (it damages the edge). For HSS sharpening use K60-K80. For sanding soft wood start with K80, for hard wood K100. Increase progressively: each grit approximately doubles the fineness.
Normal corundum or zirconia corundum?
Normal corundum for wood (red); zirconia corundum (blue) for metal or intensive use, it is self-sharpening.
Normal corundum is the universal choice for wood and finishes. Zirconia is more aggressive, recommended for iron and light alloys, and maintains its edge due to its self-sharpening action (fragments exposing new grains).
Which machine/size is it compatible with?
Check the title for belt dimensions (e.g., 75×533 mm, 100×610 mm) or disc dimensions (Ø 115, 125, 150 mm).
Abrasive belts should be chosen based on the circumference of the sander's roller. Common sizes: 40×303 mm (handheld), 75×533 mm (benchtop), 100×610 mm (semi-industrial). Also check the direction of travel (arrows on the back).
How many pieces does the package contain?
See "Packaging" or "Quantity" in the product's technical specifications.
Krollit supplies standard manufacturer packaging (typically 5, 10, or 25 pcs). For intensive professional use, it is advisable to keep a stock of at least 2-3 packages of different grits.
How to store abrasive consumables?
In a dry place, away from heat sources and humidity, keeping the original packaging closed.
Humidity degrades the binder of the abrasive paper and drastically reduces its lifespan. For unused belts, suspend them vertically to prevent permanent creases that cause slippage during operation.
