3M PN-DH Precision Shaped Grain, 150 mm, Extra Coarse Grade, 25 Grit 25 Per Pack

This grinding disc is a precision surface conditioning product designed to prepare and finish metal substrates in industrial environments. It combines shaped abrasive technology with a non‑woven web to remove material efficiently while preserving base geometry, making it suitable for low‑pressure finishing tasks in automation, electronics, electrical and mechanical workflows.

• Precision‑shaped grain for Faster material removal and extended life
• Extra coarse P150 grade delivers aggressive stock removal for Rapid finishing
• Safe operating limit 10,000 r/min supports high‑speed bench and portable tools
• 8mm bore suits small‑spindle and mandrel‑mounted applications
• Bright colour coding for simple identification on busy production lines

• Suitable for surface cleaning and finishing of stainless steel components
• Ideal for deburring and edge‑blending on aluminium assemblies
• Used for preparation of carbon steel prior to subsequent processes
• Can be used for removing weld spatter in fabrication cells
• Suitable for integration into automated finishing stations with small spindles

The non‑woven construction combined with precision‑shaped abrasive removes contaminants and evens surfaces while avoiding gouging, so stainless steel, aluminium and soft metals retain original dimensions.

It is supplied in packs of 25, offering consistent ready‑to‑fit discs for continuous operations and reduced changeover frequency.

The disc is designed to work with hook‑and‑loop and Roloc‑style mounting systems commonly used in finishing and fabrication tooling.

The blended web provides enough conformability to follow contours while the shaped grain maintains cutting performance and wear resistance during sustained use.
