Foam removal attachment

An attachment for use with a tool having a rotating shaft, said attachment comprising:

• a core, said core having an inner passage selectively attachable to said shaft and an outer profile;
• and
• a shell comprising a cavity, an outer wall, a first projection with a first projection passage and a second projection with a second projection passage,
• wherein:
• said core is received within said cavity;
• said first projection passage and said second projection passage pass exterior of said outer wall;
• and
• said first projections has:
• an external primary clearance angle of approximately between 0 and 30 degrees;
• a rake angle of approximately between-20 and 90 degrees;
• a secondary primary clearance angle of approximately between 0 and 90 degrees;
• and
• a pass-through clearance angle of approximately between 0 and 120 degrees.

An attachment for removing foam, said attachment comprising:

• a cavity;
• an outer wall;
• a first end;
• a second end, said second end having a second end wall with a second end opening through said second end wall, said second end also having a primary slot, said primary slot being open to said second end opening and passing through said outer wall;
• and
• a plurality of projections having a passage therethrough extending from said outer wall, wherein the plurality of projections has a first projection, said first projection has:
• an external primary clearance angle of approximately between 5 and 15 degrees;
• a rake angle of approximately between 25 and 35 degrees;
• a secondary primary clearance angle of approximately between 40 and 50 degrees;
• and
• a pass-through clearance angle of approximately between 80 and 90 degrees.

An attachment for removing foam, said attachment comprising:

• a first end;
• a second end;
• and
• an outer wall with a plurality of projections, each of said plurality of projections having a passage therethrough,
• wherein said second end has an opening and a primary slot, said primary slot being open to an end wall opening and through said outer wall.
