Frequently Asked Questions
Which grit size should I choose for my work?
K36-K60 for roughing and removing paint/glue; K80-K120 for intermediate sanding; K150-K240 for pre-painting finish.
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 zirconium corundum?
Normal corundum for wood (red); zirconium corundum (blue) for metal or heavy-duty use, it is self-sharpening.
Normal corundum is the universal choice for wood and finishing. Zirconium is more aggressive, recommended for iron and light alloys, and maintains its edge thanks to its self-sharpening action (fragments expose 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 are in the package?
See "Packaging" or "Quantity" in the product data sheet.
Krollit supplies standard manufacturer packages (typically 5, 10, or 25 pieces). For intensive professional use, it is advisable to keep a stock of at least 2-3 packages of different grit sizes.
How should abrasive consumables be stored?
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, hanging them vertically prevents permanent creases that cause slippage during operation.
