Indasa 6" HT Line (High Tech) Rhynogrip Ultravent Sanding Discs (8660 Series) are a high-performance abrasive that is revolutionizing the industry with advances found nowhere else by offering a wide range of applications from heavy-duty sanding to micro-fine finishing plus available in Ultravent for maximum dust extraction.

Indasa HT Line performs similar to the Indasa RedLine series but it imparts a color change as the disc wears allowing the operator to know when it is time to change out the sanding disc.

The Indasa HT Line features flexible backing adaptable to sanding contoured surfaces, special abrasive grain and stearate lubricant layer for the highest quality surface finish, high stock removal and minimal grit shedding, and a very long working lifetime.

HT Line is an excellent choice for sanding body fillers, primers, top coats, clear coats, fiberglass & gel coat materials, solid surfaces, and hardwoods.

Ultravent HTLine discs are available in a 6" size, grit range from 80 to 2,000, and sold 50 discs per box. The Ultravent pattern is 21-holes for grits 80 to 180, 57-holes for grits 220-2000.

Best performance when used in conjunction with Indasa Ultravent Multi-hole Backup Pad and Ultravent Foam Interface Pad but will also work fine with other 6" hook & loop backup pads with any vacuum pattern.
