Frequently Asked Questions
Which grit should I choose for my work?
K36-K60 for roughing and removing paint/glue; K80-K120 for intermediate sanding; K150-K240 for pre-painting finishing.
K36 grit is too aggressive for sharpening tools (damages the edge). For HSS sharpening use K60-K80. For sanding soft wood start with K80, for hard wood K100. Progress incrementally: each grit approximately doubles the fineness.
Regular aluminum oxide or zirconium oxide?
Regular aluminum oxide for wood (red); zirconium oxide (blue) for metal or intensive use, it is self-sharpening.
Regular aluminum oxide is the universal choice for wood and finishes. Zirconium is more aggressive, recommended for iron and light alloys, and maintains its edge thanks to its self-sharpening action (fragments that expose new grains).
What machine/size is it compatible with?
Check the title for the belt dimensions (e.g., 75×533 mm, 100×610 mm) or disc (Ø 115, 125, 150 mm).
Abrasive belts must 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 data sheet.
Krollit provides 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 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 belts not in use, hanging them vertically prevents permanent creases that cause slipping during operation.
