Frequently asked questions
Which grit should I choose for my job?
K36-K60 for roughing and paint/glue removal; K80-K120 for intermediate sanding; K150-K240 for pre-painting finish.
K36 grit is too aggressive for sharpening tools (it ruins the edge). For HSS sharpening use K60-K80. For sanding on soft wood start with K80, on 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 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 the self-sharpening action (fragments that expose new grains).
Which 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 should be chosen according to the circumference of the sander 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 "Package" or "Quantity" in the product technical 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 grits.
How is the abrasive consumable 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 slippage during operation.
