Technical Specs

RUPES PROCUT Discs are engineered for high‑efficiency sanding across automotive, marine, woodworking, and industrial applications. Built on a durable PET film backing with resin‑over‑resin bonding, these discs deliver a stable cutting action, excellent tear resistance, and long service life. The abrasive system uses a blend of ceramic and aluminum oxide grains in the coarse–medium range, transitioning to aluminum oxide for finer finishing grits. Designed to maintain consistent performance on flat, curved, and contoured surfaces.

• Disc Size: 6" (150mm) hook & loop grip, 15‑hole pattern
• Grain Composition:
  • P40–P320: Blend of ceramic + aluminum oxide
  • P360 and finer: Aluminum oxide
• Bonding: Resin over resin (R/R)
• Backing: PET film (polyester) — high flatness, high tensile strength
• Coating: Resin over resin with semi‑open strewed grain layout; select grits include anti‑clogging stearate treatment
• Color: Green
• Grit Range: P40, P80, P120, P180, P220, P320, P400, P600, P800, P1000, P1200, P1500, P2000
• Packaging: 50 discs per box

Grit Selection Guide

Choosing the correct grit is essential for achieving the best sanding results. RUPES PROCUT Film Discs follow a predictable progression that makes it easy to move from heavy material removal to fine finishing. Use the guide below to select the right grit for your application:

P40–P120 (Heavy Cutting & Shaping) Ideal for aggressive stock removal, leveling body filler, shaping putty, and knocking down high spots. These coarse grits cut fast and establish the initial surface profile.

P150–P320 (Surface Preparation & Primer Sanding) Best for refining surfaces after initial shaping, smoothing primer, and preparing panels for basecoat. These grits produce a consistent scratch pattern that is easy to cover and ideal for uniform surface prep.

P400–P2000 (Finishing & Pre‑Polish Refinement) Designed for fine finishing, sanding clear coat, refining gelcoat, and preparing surfaces for polishing. Higher grits (P800–P2000) pair perfectly with RUPES WET&DRYFINISH foam discs for a seamless transition into the polishing stage.

Applications

• Coatings: Paint, primer, putty, gelcoat

Compatibility

These 6" discs are designed for 15‑hole vacuum backing pads but also work extremely well on most 6" hook‑and‑loop pads with 6‑hole, 9‑hole, or multi‑hole patterns due to their universal alignment and efficient dust‑extraction design.

These discs will work great with the following sanding machines:

• RUPES 6" Skorpio III, Skorpio-E sanders 
• 3M 6" Electric and Pneumatic sanders 
• Bosch 6" sanders
• Festool 6" ETS / ROTEX 150mm sanders 
• Mirka 6" DEROS, DEROS RS, PROS, MR sanders

SMSDistributor Expert Notes

The RUPES PROCUT Film Abrasive Discs stand out as a highly refined, professional‑grade solution that integrates seamlessly into modern sanding workflows. What immediately distinguishes PROCUT is the balance between cutting speed and control: the ceramic grains in the coarse and medium grits (P40–P320) remove material quickly while maintaining a predictable, uniform scratch pattern that technicians can trust, especially in collision repair environments where consistency matters.

The PET film backing is another meaningful upgrade — it resists edge‑tearing, stays flat under load, and maintains stability on DA sanders far better than traditional paper-backed discs, which helps reduce wasted discs and improves overall workflow efficiency. Although RUPES states these are for dry sanding use, we've found they do very well in wet sanding applications, but test first for your own particular application.

Dust management is an area where PROCUT performs exceptionally well. The stearate layer and precision coating work in tandem with today’s dust‑extraction systems, keeping discs cleaner for longer and extending usable life. This makes PROCUT a strong fit for shops that rely on high‑efficiency vacuum sanders and want to maintain a cleaner work environment.

In practice, PROCUT fills a useful middle ground in the abrasive market: it cuts faster than many aluminum‑oxide discs while delivering a more refined finish than aggressive ceramic-only systems.

For technicians moving from shaping and leveling into finishing stages, the transition is smooth — pairing PROCUT’s higher grits (P800–P2000) with RUPES WET&DRYFINISH foam discs creates a predictable, streamlined workflow that prepares surfaces perfectly for polishing.

FAQ

Q: What is the difference between traditional paper and PROCUT film backing?
A: Film-backed discs are stronger, flatter, and more durable than traditional paper discs. Paper can tear, lose shape, and load quickly, while PROCUT’s PET film backing stays stable under pressure, resists edge‑tearing, and allows for more precise grain placement. This results in cleaner dust extraction, a more consistent scratch pattern, and longer disc life in professional sanding environments.

Q: Are these discs ceramic or aluminum oxide?
A: It depends on the grit! P40–P320 are a blend of ceramic and aluminum oxide grains, allowing for a more aggressive cutting action. P360 grit and finer transition to an aluminum oxide grain, allowing for a more consistent and better resulting finish.

Q: Can these be used wet?
A: PROCUT abrasives are optimized for dry sanding. In our testing, these discs work very well with water, but RUPES designed for dry use sanding. For wet sanding, use RUPES WET&DRYFINISH or WETFINISH foam discs.

Q: Do they work with non-RUPES sanders?
A: Yes, they fit any 150mm (6") hook-and-loop sander with a 6-hole, 9-hole, 15-hole or multi-hole pattern.

Q: Are these discs good for gelcoat?
A: Yes, PROCUT performs very well on gelcoat for defect removal and surface leveling.

Q: Are these discs good for wood?
A: Yes, PROCUT performs very well on wood surfaces and offers very good dust removal when used in conjunction with a good vacuum sander setup.
