SG6 Straight Grinder and Polisher – 110V and 240V Models
The SG6 straight grinder and polisher is a heavy-duty variable speed machine for grinding, deburring, blending, polishing and surface finishing applications. With a 150mm / 6″ wheel capacity, constant speed electronics and adjustable speed control, it is a versatile choice for workshop, fabrication and industrial metal finishing use.
This product page covers both the 110 Volt SG6 and 240 Volt SG6 models. The core machine platform is the same, but the voltage and power input differ between the two versions. Please select the correct voltage before ordering.
The SG6 can be used with compatible abrasive wheels, polishing mops and finishing accessories, provided the selected accessory is suitable for the machine speed, spindle, diameter and intended application.
Key Benefits of the SG6
The SG6 is designed for users who need more power, control and wheel capacity than a small rotary tool or handpiece can provide. It is particularly useful where larger abrasive wheels, flap wheels, finishing wheels or polishing mops are required for controlled grinding, blending and polishing.
Variable speed control
The SG6 can be adjusted between 1600 and 4800 rpm, allowing the speed to be matched to the accessory, material and finishing stage.
Grinding and polishing capability
Suitable for grinding, deburring, blending and polishing when used with the correct abrasive wheels, polishing mops, arbors and finishing accessories.
Constant speed electronics
Electronic speed stabilisation helps maintain a more consistent finish at the selected speed setting.
150mm wheel capacity
The machine accepts compatible wheels and mops up to 150mm / 6″ diameter, making it suitable for larger surface finishing tasks.
Extra-long spindle
The long spindle design improves compatibility with wider abrasive wheels and suitable polishing accessories.
Controlled machine operation
Soft start, overload protection and a thermally insulated front grip support smoother operation, comfort and control during use.
Common Applications
The SG6 straight grinder and polisher is suitable for a wide range of metal finishing and workshop applications, particularly where a larger wheel or mop is required for access, coverage or controlled surface finishing.
- Grinding and surface preparation
- Deburring and edge blending
- Polishing metal components
- Finishing fabricated parts
- Blending welds and worked areas
- Using compatible abrasive wheels, flap wheels and polishing mops
