3M PN-DH Aluminium Oxide, 100 mm, Fine Grade, P150 Grit 25 Per Pack

3M Scotch-Brite Precision Surface Conditioning Discs Series Grinding Disc, 115mm Disc Diameter, Fine Grade - 7100275836

This grinding disc is a precision surface conditioning solution designed for controlled material finishing and cleaning in industrial settings. It combines shaped abrasive grain with a non‑woven web to remove surface contaminants and refine finishes on metals while maintaining workpiece geometry. Supplied in packs for repetitive production tasks, it is intended for low‑pressure operations across a range of substrates encountered in automation, electronics and mechanical work.

Features & Benefits

• Precision‑shaped grain for increased cutting speed and life
  Non‑woven construction for consistent surface conditioning and finish
  Fine P150 grade provides finer material removal and smoother finish
  Bright colour coding for Rapid identification of grade and type
  Compatible with 22.23mm bore attachments for quick fitment
  Rated to run at high‑speed applications up to 13,300 r/min

Applications

• Suitable for final finishing of stainless steel components
  Ideal for deburring in electrical enclosure manufacture
  Used for surface preparation before coating in mechanical assemblies
  Can be used for lightweight cleaning of aluminium parts
  Used with hook‑and‑loop or Roloc™ holders for robotic cells

How are these discs typically mounted for automated operations?

They are compatible with 22.23mm bore mounting systems and fit hook‑and‑loop or Roloc™‑style holders for Rapid changeover in automated spindles and robotic end‑effectors.

What pack quantity should workshop planners expect for continuous production?

Components are supplied in bulk packs of 25 to support frequent replacement cycles and minimise tool‑change downtime.

Which substrates respond best to the fine P150 grade on this disc?

The P150 grit is particularly suited to stainless steel and soft metals where a controlled, fine finish is required without altering part geometry.

Can these discs be used at high peripheral speeds?

They are specified for use up to a maximum safe speed of 13,300 r/min, enabling compatibility with high‑speed angle grinders and dedicated finishing spindles.
