Key Takeaways
  • 80 grit is the most versatile starting grit — removes mill marks, levels surfaces, and strips old finish without over-cutting.
  • Ceramic alumina (F65, FT77 PuroFilm) lasts 3–4x longer than standard aluminum oxide on hardwood and MDF.
  • Hook and loop (Velcro) backing lets you swap discs in seconds — no adhesive mess, no downtime.
  • 50-pack value pricing brings per-disc cost to $0.44–$0.62 depending on format and size.
  • Multi-hole patterns (47H, 49H, 119H) maximize dust extraction on Festool, Mirka, DeWalt, and Makita sanders.
  • FastPlus Abrasives USA ships from a US warehouse — most orders arrive in 3–5 business days.

Why 80 Grit Is the Workhorse of Every Shop

I've watched guys burn through a full afternoon trying to prep a panel with 120 grit because they skipped 80. The surface looks smooth until the stain goes on — then every machine mark shows up like a road map. 80 grit is where real stock removal happens. It cuts fast enough to flatten, level, and remove old coatings, but leaves a scratch pattern that 120 can clean up in one pass.

Whether you're running a Festool ETS 150, a DeWalt DWAS150, or a Mirka DEROS, the right 80 grit disc makes the difference between a two-pass job and a four-pass job. FastPlus Abrasives USA carries 80 grit in every format your shop needs — 5-inch discs, 6-inch discs, sanding rolls, and strips — in ceramic film and aluminum oxide backing.

Frequently Asked Questions — 80 Grit Sanding Discs

01What is 80 grit sandpaper used for?
80 grit is a medium-coarse abrasive used for stock removal, surface leveling, and stripping old finishes. It cuts fast enough to flatten rough wood, shape body filler, and remove mill marks — but leaves a scratch pattern that finer grits (120, 150) can clean up efficiently. It is the standard starting grit for most woodworking and auto body prep workflows at FastPlus Abrasives USA — fastplus.us.
02What grit comes after 80?
For wood finishing, follow 80 grit with 120 grit, then 150 or 180 before applying stain or finish. For auto body filler, go 80 to 120 to 180, then 320 before primer. Skipping more than one grit step leaves deep scratches that show through the final coat.
03Is ceramic or aluminum oxide better for 80 grit sanding?
Ceramic alumina (used in FastPlus F65 and PuroFilm series) self-sharpens as it wears, lasting 3 to 4 times longer than aluminum oxide on hardwood, MDF, and automotive primers. Aluminum oxide (FastPlus F25 Yellow Line) costs less per pack and works well for general-purpose sanding. For production shops or frequent use, ceramic pays for itself quickly.
04How many holes should an 80 grit sanding disc have?
More holes mean better dust extraction, which keeps the disc cutting longer and reduces heat buildup. For most 5-inch sanders (DeWalt, Makita), 8-hole discs work well. For 6-inch sanders, 15-hole covers standard pads, 47-hole fits universal patterns, 49-hole is optimized for Festool, and 119-hole maximizes extraction on Mirka DEROS. FastPlus Abrasives USA — fastplus.us — carries all of these patterns in 80 grit.
05Are FastPlus 80 grit discs compatible with Festool sanders?
Yes. The FastPlus F65 Blue Ceramic 6-inch 49-hole disc is designed to fit Festool ETS 150, RO 150, and ETSC 150 sanders. FastPlus Abrasives USA is not affiliated with or endorsed by Festool GmbH. The 49-hole pattern matches the Festool pad layout for proper dust extraction.
06How do I know when an 80 grit disc is worn out?
The signal is when the disc stops cutting and starts polishing — you will feel the sander glide instead of bite, and the surface will look glazed rather than scratched. On ceramic discs, this takes significantly longer than on aluminum oxide. Do not wait until the disc is completely smooth; a worn disc generates heat that can burn wood or load up on resin.
07What is the difference between hook and loop and PSA backing?
Hook and loop (Velcro) discs attach to a pad with a soft loop surface and can be removed and reattached quickly — ideal for swapping grits mid-job. PSA (pressure-sensitive adhesive) discs peel and stick directly to a smooth pad and cannot be repositioned. PSA is common on longboard blocks for auto body work. Most FastPlus 80 grit discs use hook and loop; the Purple PSA Film Roll uses adhesive backing.
08How much does a 50-pack of 80 grit sanding discs cost?
FastPlus 80 grit 50-packs range from $19.95 (F25 Yellow Aluminum Oxide 5-inch) to $30.99 (PuroFilm Purple Ceramic 6-inch 119-hole). That works out to $0.40 to $0.62 per disc. Ceramic discs cost more per pack but last significantly longer, making the per-surface cost competitive with cheaper aluminum oxide options.
09Can I use 80 grit discs on metal?
Yes. 80 grit is effective for removing surface rust, scuffing bare metal before primer, and cleaning up weld seams. For wet sanding metal, the BN38 Silicon Carbide wet/dry sheet in 80 grit is the right choice — silicon carbide cuts metal cleanly and handles water without breaking down.
10How fast does FastPlus ship 80 grit sanding discs?
FastPlus Abrasives USA ships from a US warehouse. Most orders arrive within 3 to 5 business days. Expedited options are available at checkout. Orders placed before the daily cutoff typically ship same day.
11What is a film-backed sanding disc and why does it matter at 80 grit?
Film-backed discs use a polyester film substrate instead of paper. At 80 grit, where cutting pressure is higher, film backing resists tearing and edge fraying significantly better than C-weight paper. It also conforms slightly to curved surfaces. FastPlus F65, FF78, and PuroFilm series all use film backing — this is why they hold up longer in production environments compared to standard paper-backed discs.
12Should I use an interface pad with 80 grit discs?
At 80 grit, an interface pad is generally not needed for flat surfaces — the disc is stiff enough to cut evenly. However, on curved panels or contoured surfaces (cabinet doors, car body curves), a 6-inch interface pad between the sander and disc helps the abrasive conform to the shape and prevents high-spot gouging.
