These 80/80 grit square nail files are made in Canada using Japanese sandpaper. Japanese sandpaper is known in the professional nail industry for its consistency and durability. The abrasive surface stays aggressive longer than files made with lower-grade grit materials, which means you get more reliable performance across a full day of acrylic services.
The square tip gives you precise access to the corners of the nail and the side walls without the rounded tip rounding off areas you want to keep defined.

Understanding 80 Grit
Nail file grit refers to the number of abrasive particles per square centimetre on the file surface. The lower the number, the coarser the abrasion. Here is where 80 grit fits within the professional nail file range.
- 80 grit: Extra coarse. Used for heavy product removal, rapid length reduction, and breaking down thick artificial nail enhancements.
- 100 grit: Coarse. Used for shaping side walls and the free edge on acrylic and artificial nails.
- 180 grit: Fine. Used for contouring, natural nail prep, and finishing artificial nails to a smooth surface.
An 80/80 file carries the same extra coarse grit on both sides, giving you consistent aggressive removal across the full file surface with no need to flip or rotate looking for a fresher side.
Frequently Asked Questions
Why does the sandpaper material matter on a nail file?
Files made with Japanese sandpaper hold their abrasive surface longer than those made with lower-grade alternatives. For a nail technician doing multiple acrylic sets per day, a file that stays sharp through more uses means fewer replacements mid-service and more consistent results across every client.
What is the difference between a square tip and a regular nail file shape?
A square tip file gives you direct access to the corners and side walls of the nail enhancement without the rounded end softening those angles. For nail technicians who work with square or squoval acrylic shapes, a square tip file is the more precise tool for defining those corners cleanly. It also sits flush against the side wall without the curved end catching on the skin alongside the nail.
When should I use an 80 grit file versus a 100 grit file?
Reach for the 80 grit when you need maximum product removal speed, such as taking down thick acrylic, removing significant length, or breaking down heavy gel product before backfilling. Move to 100 grit once you are into shaping and refining the free edge and side walls. The 80 grit is too aggressive for detail shaping work but nothing moves product faster when bulk removal is the goal.
Can I use an 80 grit file on natural nails?
No. An 80 grit file is far too coarse for the natural nail plate and will cause thinning, damage, and sensitivity. It is designed exclusively for use on acrylic, gel, and other artificial nail products. For natural nail work, a 180 to 240 grit file is the appropriate range.
Where can I buy bulk nail files made in Canada for my salon?
You can order these 80/80 grit square nail files in a pack of 50 online through CM Nails Supply, a professional nail and beauty supply store serving nail technicians and salon owners across Canada with fast shipping options.
