The Wielander + Schill WS 457 pneumatic belt sander is a high-quality, high-performance tool specifically designed for the final machining of body surfaces and for performing precision work in narrow areas. This robust yet lightweight tool is the ideal choice for the quick and efficient removal and separation of weld points, weld seams (MIG-MAG, laser welding), and other materials.
The main strength of the device lies in its extremely fine adjustability, which allows the user to continuously adjust the sanding speed by raising or lowering the arm to suit the specific task and material.
The WS 457 belt sander delivers outstanding performance in the following areas:
Weld Point Removal: Especially effective for the safe and precise removal of weld points on high-strength steels (e.g., Usibor, BTR-BOR).
Weld Seam Machining: Excellent for finishing and leveling MIG-MAG weld seams as well as laser welding seams.
Accessing Tight Spaces: Thanks to its compact design, it is ideal for sanding inaccessible, narrow body parts and hard-to-reach corners.
Important Note: For the removal of weld points, seams, and laser welding seams, the use of premium quality K36, K60, and K80 grit sanding belts is exclusively recommended for maximum efficiency and tool protection.
The WS 457 pneumatic belt sander ensures reliable operation and a long service life thanks to its detailed technical parameters.

One of the most important ergonomic and functional features of the belt sander is the infinitely variable speed control. By gently moving the arm (raising/lowering), the user can ideally adjust the speed to the sanding task (e.g., fine polishing or coarse material removal). This function increases workpiece quality and reduces the risk of overheating.
The tool is constructed from a combination of metal and plastic elements, which guarantees high durability even in workshop environments. Weighing only 0.85 kg, it is extremely light, enabling long, fatigue-free work, especially in hard-to-reach areas.
Proper pneumatic supply and maintenance are essential to ensure the optimal lifespan and performance of the tool.
For the proper protection of the pneumatic system, Wielander + Schill recommends the following accessories:
Pressure Reducing Valve (7 bar, Item No.: 194000): Excessive operating pressure significantly reduces the lifespan of pneumatic tools. This valve prevents damage and is recommended for all bodywork tools.
Compressed Air Mini Oiler (1/4″, Item No.: 637103): Reduces wear and improves tool operation. Thanks to the transparent window, the user can monitor the oil level, avoiding over-oiling.
Pneumatic Special Oil (1000 ml, Item No.: 698001): This high-performance oil is specifically designed for air lubrication systems and maintenance units, complying with the ISO 3448 VG 32 viscosity class (32 mm²/s at 40 °C). It offers excellent aging resistance, corrosion and wear protection, and superior water separation properties.
Ensuring proper maintenance and air quality according to standards (ISO 8573-1) is crucial for the reliable operation of the tool.
For quick and safe connection, the following elements can be used (not included in the package):
Quick Connector for Compressed Air (Type 26, 9 mm, Item No.: 697002)
Air Coupling (Type 26, DN 8, G 1/4″, Item No.: 697003)
The Wielander + Schill WS 457 pneumatic belt sander offers body repair specialists a reliable and precise solution that significantly speeds up the final surface preparation phases while guaranteeing an excellent quality result.
