Main Features of the Royce Mini Grinder
1. Compact Electric Motor
The Royce RDG135-211T is advertised with a 135W electric motor.
The motor drives small rotary accessories at high speed, making the machine suitable for detailed grinding, polishing and cutting.
It is useful for tasks where a large grinder would be difficult to control.
However, it is not designed to replace a heavy-duty angle grinder when cutting thick metal or carrying out continuous industrial grinding.
2. Variable Speed Control
The Royce mini grinder has adjustable speed settings.
The RDG135-211T is advertised with a no-load speed range of approximately 10,000 to 32,000 revolutions per minute.
This allows users to select a suitable speed for different materials and accessories.
Lower speeds may be suitable for selected polishing and delicate finishing jobs, while higher speeds may be useful for certain grinding and engraving operations.
Always follow the accessory manufacturer’s maximum speed rating.
3. Flexible Shaft for Detailed Work
Some Royce mini grinder kits include a flexible shaft attachment.
The flexible shaft allows the user to hold a smaller handpiece while the main motor remains away from the working area.
This is useful for engraving, carving, polishing and working on small objects.
It can also improve access to narrow spaces where the main tool body is too large.
The flexible shaft must be fitted correctly and used within its rated speed and bending limits.
4. Multiple Grinding and Cutting Accessories
The Royce mini grinder can be used with compatible accessories for different tasks.
Common accessory kits include grinding stones, cutting discs, sanding drums, polishing wheels and small drill bits.
This makes the machine useful for workshops that carry out several types of precision work.
The number and type of accessories depend on the package selected.
5. Shaft Lock for Easy Accessory Changes
The listed Royce RDG135-211T includes a shaft-lock feature.
This helps hold the spindle while changing compatible accessories.
Always disconnect the machine from electricity before changing a bit, disc or grinding stone.
6. Replaceable Carbon Brushes
The Royce RDG135-211T is advertised with accessible carbon brush holders.
Carbon brushes are wear parts in brushed electric motors.
When they become worn, they may need replacement using parts compatible with the machine.
This can make servicing easier compared with tools that do not provide access to the brushes.
7. Lightweight Handheld Design
A mini grinder is generally easier to handle for detailed work than a large power grinder.
The compact body allows the user to guide small attachments around edges, corners and detailed surfaces.
For accurate work, the material should be securely clamped and the operator should maintain control of the tool.

Royce Mini Grinder vs Angle Grinder

How to Choose the Best Royce Mini Grinder in Kenya
Check the Motor Power
The RDG135-211T is commonly advertised with a 135W motor.
Some other Royce-branded rotary tool listings claim 300W.
Confirm the motor rating on the actual machine’s nameplate because online product descriptions are not always consistent
Consider the Speed Range
Variable speed helps match the tool to different materials.
For example, polishing certain plastics may require lower speeds to reduce heat damage.
Grinding and engraving may require different settings depending on the accessory.
Check the Collet Size
The RDG135-211T commonly uses a 3.2mm collet.
Make sure replacement bits have a compatible shank diameter.
An incorrectly sized accessory may slip or become unstable during operation.
Confirm the Number of Accessories
Royce mini grinder kits are advertised with different accessory counts.
A 211-piece kit may offer more accessory choices than a smaller package, but the actual contents and quality matter more than the number alone.
Look for a Flexible Shaft
A flexible shaft is useful for jewellery work, engraving and detailed carving.
Confirm that the shaft and handpiece are included if you need them.
Check Spare Parts and Warranty
Ask about replacement carbon brushes, collets, cutting discs and grinding accessories.
Also confirm the seller’s warranty and return conditions.
