A3301 Pneumatic 50mm Eccentric Mini Sander with 50 Mini Discs

1/ Micro Sanding Offer

The Grade B Mini Sander ensures high power and rotational speeds up to 15,000 revolutions per minute. The orbital mini sander can accommodate 50mm or 75mm backing plates. Grade B Mini Sanders are professional-grade pneumatic tools. Amongst various quality grades from D to A, this 50mm mini sander matches the quality standards of the Japanese market, which has requirements similar to the European market. Another model of the mini sander is available at a budget-friendly price (see below).

What differentiates a budget sander from a professional sander ?

The Grade B professional mini sander delivers a sanding power far superior to consumer-grade sanders. With an equal compressed air source, a second-tier sander stops rotating when too much pressure is applied, while the professional sander maintains high performance even under increased force.

Usage :

The pneumatic mini sander is convenient to use and easy to handle. It features a speed control dial and a trigger to initiate rotation. A minimum of a fifty-litre compressor is required.

Delivery :

Supplied with a 50mm VELCRO self-adhesive pad, a pneumatic connector, and 50 micro sanding discs of 50mm from coarsest to finest (Grades: 10x320, 10x800, 10x1500, 10x2000, 10x3000).

We offer optional mini sanding pads of 50mm or 75mm, with a soft grade (red) and a standard firm grade (yellow) here.

We also offer 50mm water sanding discs with various grain finenesses (P320, P800, P1500, P2000, P3000) here.

What's the difference between a mini-sander and a mini-polisher ?

For a mini-sander, the rotational speed is much higher (12,000-15,000 rpm*) compared to a mini-polisher, which caps at 2,500 revolutions per minute.

Orbital / Excentric :

This refers to an orbital sander type with an orbit of t5.

Unlike concentric rotation, the orbital system rotates the pad on an axis that itself revolves in a circle measured in mm. This ensures no marks are left on the surface; the sanding pattern is not concentric (revolving around a fixed axis). Even if one stops moving the active sander, it won't create a hole or a sanding mark because the disc forms a variable ellipse.
