Workshop Heaven 3M™ Film Top Up Pack (Magnum)


2 sheets each of:  40 micron, 30 micron, 15 micron and 9 micron, pressure sensitive adhesive backed, aluminium oxide microfinishing film. A heavier duty version of standard lapping film with a thicker backing and a stronger resin coating

2 sheets each of: 3 micron and 1 micron lapping film. The 3 micron grade has a 'P' resin coating making it slightly more durable than the other superfine grades. The 1 micron film is roughly equivalent to an 11,000 grit Japanese waterstone

1 sheet of:  100 micron microfinishing film for heavier material removal, regrinding primary bevels for example. This can either be stuck to the back of the glass or any other convenient flat surface: absolute flatness is less critical for grinding than honing

  • Sheet Size 8½" x 11" (216mm x 279mm).
  • Each sheet can be cut into four 2½" (69mm) wide strips.
  • Mineral: Aluminium Oxide
  • Regular price if purchased individually: £45.74
