3M Cubitron II Hookit Clean Sanding Sheet Roll 737U, P40 to P400

3M Cubitron II Hookit Clean Sanding Sheet Roll 737U, P40 to P400

SKU:34442

3M's precision-shaped ceramic grain on a Hookit roll for hand blocks and file boards. The multi-hole Clean Sanding pattern pulls dust away, and kiss-cut scoring lets you tear off the sheet length your block needs.

Why it works

Sharper grain, less dust

  • Precision-shaped grain. Triangular ceramic grains, electrostatically oriented to cut.
  • Clean Sanding holes. A multi-hole pattern for dust extraction on a vacuum block.
  • Tear to length. Kiss-cut scoring gives you multiple sheet lengths from one roll.
  • Hookit. Hook-and-loop attachment for quick changes.
Put it on a dust-extraction block. 3M builds 737U to work as a system with its dust extraction blocks and equipment. The 67 mm 3M Hookit Dust Extraction Flexible Blocks match the 70 mm roll.
How to use

Block sanding

  1. Pick the roll width that matches your block.
  2. Tear the roll at the kiss-cut to the length your block needs.
  3. Mount the sheet on a Hookit block and connect dust extraction.
  4. Work through the grades: shape filler with P120–P180, finish with P220, feather-edge with P240.
  5. Block primer with P320–P400.
