Description of the MST-SBH External Lathe Sanding Device
The Prismont MST-SBH external lathe sanding device is designed to provide operators with safe, efficient, and precise finishing operations directly on machined parts—without the use of hands. Attached to the conventional lathes existing tool post, this tool securely holds abrasive belts for a variety of applications such as sanding, polishing, finishing, and deburring on metal, alloy, or wood parts during turning operations.
Compatible with both conventional and CNC lathes, the MST-SBH improves surface quality while reducing the risks associated with manual hand sanding. It eliminates the hazards of using improvised tool holders, ensuring increased operator safety and consistent finishing results.
Its ingenious design allows for:
- Easy adjustment to fit different workpiece diameters using three opening positions
- Quick replacement of abrasive belts to maximize productivity
- Direct installation on the existing tool post of conventional lathes
The MST-SBH is available in two versions to meet different production needs:
- Manual mode (MST-SBH Model) for simple and quick sanding
- Manual mode with belt clutch control (MST-SBH(A) Model) for superior rotation control, ideal for applications where precision is critical. (Important: this tool is not motorized and cannot be motorized).
Each device comes with three abrasive belts included, allowing for immediate use. In addition, this device is designed in compliance with international standards EN 12840:2001 and ISO 23125:2010, which govern the safety of machine tools, ensuring conformity with globally recognized industrial standards.

Frequently Asked Questions about the Lathe Sanding Device
What Is the Difference Between the MST-SBH and MST-SBH(A) Models?
The two series of models operate differently. The MST-SBH series is the device with the standard manual operating mode. It includes models MST-SBH1.0, MST-SBH2.0, MST-SBH4.0, and MST-SBH4.0EX. The MST-SBH(A) model uses a manual operating mode with belt clutch control for greater control of rotation. It has no motor. It includes models MST-SBH(A)1.0 and MST-SBH(A)2.0.
Which Model Should I Choose Based on the Diameter of My Parts?
The compact models MST-SBH1.0 / MST-SBH(A)1.0 are suitable for diameters up to 150 mm (6″), the intermediate MST-SBH2.0 / MST-SBH(A)2.0 up to 200 mm (8″), the MST-SBH4.0 up to 300 mm (12″), and the MST-SBH4.0EX up to 500 mm (20″). The technical specifications table above serves as a useful reference.
On What Type of Lathes and for Which Materials Can I Use This Tool?
The lathe sanding device is suitable for both conventional and CNC lathes. It can be used on metal, alloy, or wood parts during turning operations.
