xZircon Velcro sanding discs, 178 mm diameter, 10-hole — the professional choice for the Pallmann Spider parquet sander
Our high-quality zirconia-alumina hook-and-loop sanding discs, measuring 178 mm in diameter with a 10-hole dust extraction system, are the ideal specialized size for the Pallmann Spider parquet sander and comparable professional sanding systems with dust extraction. Available in 7 grits from K24 to K100 in a convenient 50-pack —the right grit for every professional sanding task. The 10-hole pattern ensures optimal dust extraction—crucial for clean work and long service life. Direct from the manufacturer-importer at attractive prices—without any middleman markup.
💡 Do you have a different machine? Our zirconium hook-and-loop sanding discs (150/180 mm) fit nearly all standard parquet sanders. For the Lägler Trio, we recommend our zirconium hook-and-loop sanding discs (200 mm).
🎯 Designed specifically for the Pallmann Spider — perfectly tailored
The Pallmann Spider is one of the most powerful parquet sanders on the market—and our 178-mm hook-and-loop discs with 10-hole vacuum ports are specifically optimized for this system. The 10-hole configuration ensures:
- Optimal dust extraction: Sanding dust is extracted directly through the perforations — up to 95% less dust in the air
- Longer service life: Since no dust accumulates on the abrasive, grinding performance remains consistent throughout its entire service life
- Consistent sanding finish: No dust particles, no scratch marks — the perfect preparation for sealing
- Clean work environment: Less cleanup after sanding, healthier air to breathe
🔵 What makes zirconia corundum special? Its self-sharpening effect
Zirconia is the premium abrasive grain for demanding professional applications. Unlike traditional corundum, zirconia has a key advantage:
- Self-sharpening effect: During grinding, the grain tips break off in a controlled manner, continuously creating new sharp grinding edges
- Up to twice the service life compared to standard corundum
- Aggressive cut: High material removal even at low contact pressure
- Cool-cutting: Less heat generation — important for hardwood and stainless steel
- Distinctive blue color: a hallmark of genuine zirconia-corundum quality
🎯 Premium Quality — Technical Highlights
Our 178-mm hook-and-loop sanding discs are manufactured to professional industry standards:
- Highly concentrated zirconia-corundum abrasive grain: Maximum abrasive grain density for high performance
- Tear-resistant fabric backing: Durable base layer designed for heavy-duty use
- Full synthetic resin bonding: Long service life even under heavy loads
- High-quality hook-and-loop fastener: Quick replacement without tools, secure hold
- 10-hole suction pattern: Precisely aligned to fit the Pallmann Spider sanding pad
📊 The right grit for every step
Our range of hook-and-loop discs includes 7 grit sizes, from K24 to K100 —select the right one using the variant selection:
- K24 (Very Coarse): Maximum material removal — old layers of varnish, heavily damaged old hardwood floors, varnish removal
- K36 (Coarse): Standard coarse sanding for parquet renovation and heavily worn wood floors
- K40 (Coarse–Medium-Coarse): Universal pre-sand for hardwood floors — removes varnish residue and evens out coarse sanding marks
- K50 (medium-coarse): A grit size that bridges the gap between coarse and medium grits — coming soon
- K60 (medium-coarse): Intermediate sanding after coarse pre-sanding — even preparation
- K80 (Medium): Standard medium-grit sandpaper for parquet flooring
- K100 (Fine): Fine sanding before sealing, painting, or oiling
💡 Pro tip for the Pallmann Spider: For heavily used hardwood floors, we recommend the following sequence: K24 → K40 → K60 → K100 — for a perfect sanding result without vibration marks. The 10-hole dust extraction system keeps the sanding disc clean and ensures consistently high sanding performance throughout the entire process.
