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 (it ruins the edge). For HSS sharpening use K60-K80. For sanding soft wood start with K80, for hard wood K100. Progress gradually: each grit approximately doubles the fineness.
Normal corundum or zirconium corundum?
Normal corundum for wood (red); zirconium corundum (blue) for metal or intensive use, it is self-sharpening.
Normal corundum 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).
Which machine/size is it compatible with?
Check the title for the belt dimensions (e.g. 75x533 mm, 100x610 mm) or disc (Ø 115, 125, 150 mm).
Abrasive belts should be chosen based on the circumference of the sander's roller. Common sizes: 40x303 mm (handheld), 75x533 mm (benchtop), 100x610 mm (semi-industrial). Also check the direction of travel (arrows on the back).
How many pieces are in the pack?
See "Pack" or "Quantity" in the product's technical specifications.
Krollit provides standard manufacturer packs (typically 5, 10 or 25 pieces). For intensive professional use, it is advisable to keep a stock of at least 2-3 packs 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 sandpaper and drastically reduces its lifespan. For belts not in use, hanging them vertically prevents permanent creases that cause slippage during operation.
