 POLISTAR®  
PFERD » Coated & Non-Woven Abrasives » POLISTAR®
POLISTAR pads are flexible tools for grinding on internal surfaces of bores or pipes. These coated abrasive, star-shaped pads offer high flexibility, and are perfect for grinding internal surfaces of small-diameter bores or pipes. Their small diameters makes these tools particularly suitable for use on 1/4“to 2“ diameter ID’s.
POLISTAR pads can be stacked in several layers. To benefit from a maximum abrasive surface area, ensure that the lobes of the individual star pads are aligned offset. - 3/4“ Dia. POLISTAR for 1/4“ to 9/16“ ID
- 1-1/4“ Dia. POLISTAR for 3/16“ to 3/4“ ID
- 1-1/2“ Dia. POLISTAR for 9/16“ to 1“ ID
- 2“ Dia. POLISTAR for 3/4“ to 1-1/2“ ID
Application Examples- Cleaning, fine grinding and ultrafine finishing of bores
- Post-weld removal of metal discolorations in stainless steel pipes
- Inlet and outlet radiusing of bores/holes
- Light deburring work on bores (removal of secondary burrs) in preparation of coating
- Deburring in cross-bores
Abrasive: Aluminum Oxide A
