ROJECO Stainless Steel Grinder Head for N30 Pet Nail Clipper
These ROJECO stainless steel grinder heads are replacements for the ROJECO N30 Pet Nail Grinder. Each head has a diamond bit surface that files nails smoothly, so when your original head wears down you can swap it instead of buying a new grinder. The pack contains two heads, so a spare is always ready.
Diamond bit grinder
The heads use an advanced diamond bit surface, which the manufacturer describes as strong and wear-resistant. Diamond grit files a nail down gradually instead of cutting it, so you can shape and smooth in small steps and avoid taking off too much at once.

Made for the N30 brushless motor
The N30 is driven by a brushless motor with a brass shaft, which the manufacturer describes as high power, low noise and long-lasting. The grinder head sits on that shaft and turns with it, so a fresh head brings back full grinding performance without replacing the motor.

Two LED lights and two speeds
The N30 has two LED lights that light up the nail while you work, and two speed settings: low speed (7000 RPM) for small or nervous pets, and high speed (8000 RPM) for larger dogs or tougher nails. Both speeds work with these replacement heads.

Frequently asked questions
Which grinder does this head fit?
The ROJECO N30 Pet Nail Grinder only. It is not designed for other models.
How do I know when to replace the head?
When grinding feels slower or uneven, or the bit looks worn. Brushing nail dust off after each session helps it last.
Is a grinder better than clippers for nervous pets?
Many owners find a quiet grinder gentler because nails are filed gradually. Our guide to electric nail grinders versus clippers compares the two.
