ABRASIVE ROLLS
Excessive side pressure on a Mandrel in use may cause it to suddenly bend
or break ejecting it at high speed causing injury or property damage.
Abrasive Rolls are best for use on intake manifolds and other deeply and tightly contoured objects.
Abrasive Rolls in both cylinders and tapers in (#13129 – 80 Grit , #13131 – 220 Grit, #13132 –
320 Grit) are available from Eastwood. These rolls are used with a High Speed Pneumatic or
Electric Die Grinder. The Mandrels for these rolls are available in lengths from 2 3/4" to 6" long.
For safety, always use the shortest mandrel that will reach.
The abrasive rolls are best used with light side pressure, letting the spinning abrasive roll do
the cutting rather than excessive side pressure which can suddenly bend a mandrel.
To mount: insert the glued end of the abrasive roll fully onto mandrel extension and twist clockwise
until tight.
NOTE: Enlarge mounting hole slightly with an awl to ease mounting rolls on mandrel.
Mount mandrel with abrasive roll in pneumatic or an electric die grinder (22,000 rpm maximum
speed). The abrasive roll will tend to tighten itself further in use. If using abrasive rolls on softer
metals like aluminum, or for a smoother cut, apply Grinder's Grease (#13119) or Tripoli Compound
(#32032) to the spinning abrasive roll. Apply spinning Abrasive Roll to work surface using light
pressure. The underlying abrasive will become exposed as the roll is used.
As with all polishing and buffing processes, change the contact angle by 90° (or as close to 90°
as the part will allow) so that you can see when the previous grit marks have been re- moved.
Before buffing, aluminum and other soft metal surfaces need to have a surface as smooth or smooth-
er than what a 220 grit abrasive would yield. Stainless Steel and other hard metals should be brought
to a 400-600 grit or finer finish before using the buffing wheels and compounds. Using buff wheels
and compounds on surfaces rougher than recommended will result in an uneven surface.
