3M PN-DH

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.

• 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

• 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

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.

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

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

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.
