Klingspor 125280 SK 500 Flexible Sanding Block, Corundum P100, 100 x 70 x 25 mm, Pack of 100

For professionals who demand consistent, high-quality surface finishing, the Klingspor SK 500 sanding block offers a level of control and durability that standard abrasive sheets cannot match. Built around a flexible foam core and coated with sharp corundum abrasive, this block conforms to contours while maintaining a flat, even contact area for efficient material removal. Each block measures 100 x 70 x 25 mm and is supplied in a bulk pack of 100, making it a cost-effective solution for workshops, bodyshops, and industrial surface preparation.

Highlights

• Flexible foam backing adapts to curved and profiled surfaces without losing shape
• Corundum abrasive with P100 grit delivers fast cutting action on wood, metal, paint, and fillers
• Rectangular block design provides a secure grip and even pressure distribution
• Resin bonding ensures high grain adhesion and long service life
• Dry sanding only – ideal for manual deburring, paint removal, and surface preparation
• Bulk pack of 100 blocks reduces replenishment frequency and lowers cost per unit

In daily use

Whether you are smoothing filler on a car body panel, breaking edges on freshly machined metal parts, or preparing wooden furniture for coating, the SK 500 block delivers consistent results. The P100 grit is coarse enough to remove material quickly, yet fine enough to leave a surface ready for subsequent finer grits. Because the block is flexible, it follows gentle contours without digging in, reducing the risk of gouging. The foam core also dampens vibration, making extended sanding sessions less fatiguing.
