All Pads Are Not Created Equal

The backing pad is a very important interface between the tool and your work. A quality pad performs three main functions.

First, it provides a flexible, yet flat surface to mount the abrasive to the tool. Second, a quality pad has a controlled weight and mass that balances with your tool and allows the tool to operate with minimum vibration. Third, a quality pad will be long lasting.

The difference between quality pads and other pads can be seen in their components and construction.

7

Our quality pads have:

1 A specially designed, environmentally friendly,

6

molded polyurethane foam, that dampens vibration to prevent your tool from bouncing, yet is flexible and tough enough to withstand the rigorous operation of dualaction random orbit sanders. A permanent bond between the polyurethane and other components of the pad eliminates separation problems.

5

2 A rugged thermoset fiberglass epoxy backing, that withstands the abuse of heat, flexing and impact, to keep the pad running flat and true for a long time. Aluminum backings bend from impact and lose their flatness, while heat and flexing cause molded plastic backings to warp, distorting the face of the pad.

A pad that is not flat causes vibration which fatigues the user and prevents creating a professional finish.

3 Full 1/2” diameter vacuum holes that match standard paper and allow maximum performance of your tools’ vacuum system.

4

4 A durable welded and plated stud assembly on random

orbital pads. Welding assures a permanent alignment between the pad and the tool. Plating assures easy pad removal by preventing corrosion.

5 A stud assembly that is rigidly attached to the backing

with four rivets on random orbital pads. Stud assemblies that are molded in place can loosen and strip, causing poor performance and difficulties when removing the pad from the tool. A large, flat, raised steel washer with a four rivet attachment forms an ideal distributor of stress. This assures perfect alignment with all tools, and allows the pad to remain in service for a long time.

6 An embossed vinyl facing

3

2

1

or hook facing that is intimately molded with the polyurethane to create a permanent durable and flat surface. Embossed vinyl facings offer maximum adhesion with PSA style paper while operating the tool, yet allow quick and easy replacement. Quality hook facings also offer secure adhesion yet quick and easy removal.

7 Strict tolerance on weight, balance, roundness, and flat-

ness. A pad that is not the correct weight, out of round, out of balance, or uneven causes vibrations which fatigue the user and prevents creating a professional finish. Strict tolerances assure you that each pad performs consistently for a long time.

WARNING: Face & eye protection must be worn while operating power tools, per ANSI

B186.1. Cutting tool maximum speed rating must be equal or exceed speed of air tool @

90 psi (620 kPa). Follow cutting tool manufacturer’s mounting & operating instructions.
