Angle grinder 125 mm 18 V LI-ION 5.0 Ah BLDC Makpac DGA504RTJ

Mobility and Efficiency with 125 mm Discs

Working with an angle grinder in locations without access to the electrical grid is no longer a problem when the tool offers sufficient power and ergonomics. The DGA504RTJ model is a professional device from the LXT series, designed to replace traditional corded angle grinders in many applications. Thanks to its 18 V voltage and brushless motor (BLDC), the tool delivers high performance while maintaining compact dimensions. The overall length of the device is 362 mm, which, combined with a narrow motor housing, ensures a secure grip even when working in hard-to-reach areas.

The kit includes a complete system ready for immediate use. The MAKPAC system case protects the tool and contains everything needed to start work: the angle grinder itself, two 5.0 Ah batteries (model BL1850B), and the DC18RC charger. This configuration eliminates downtime – while one battery is in use, the other can be charging or ready for replacement. Please note that the device is compatible with Li-ion batteries with capacities ranging from 1.5 Ah to 6.0 Ah; however, it does not support older non-electronic models (G series) or the very small 1.3 Ah battery.

XPT Technology and User Safety

A key element of the design is XPT (Xtreme Protection Technology), which enhances the tool's resistance to dust and moisture. This allows the angle grinder to be used in demanding construction or workshop conditions without concern for rapid wear of internal components due to contamination. The BLDC motor not only ensures a longer service life (no brushes requiring replacement) but also automatically adjusts the rotational speed to the type of work being performed, resulting in stable cutting or grinding.

Operator safety has been addressed through an anti-restart function. This system prevents accidental tool startup after the battery is reinstalled – the grinder remains off until the user consciously presses the switch. The no-load rotational speed is 8500 rpm, which is optimal for discs with a diameter of 125 mm and an M14 thread. The maximum thickness of discs used is 6.4 mm (1/4 inch), and the standard mounting hole diameter is 22.23 mm.

Applications and Scope of Delivery

The tool is ideal for cutting metal, stone, or concrete, as well as for grinding welds and edges. The weight of the device, depending on the configuration (with or without battery), ranges from 2.26 kg to 3.73 kg (according to EPTA standards), allowing for prolonged work without excessive hand fatigue. The kit also includes all necessary mounting accessories: a disc guard, a side handle for better control, a locknut wrench, and a flange.

All key technical specifications have already been covered in the feature and application descriptions above – from the 18 V voltage and 8500 rpm rotational speed to compatibility with 125 mm diameter discs and M14 threads. It is worth noting the noise level of 79 dB – a typical value for this type of cordless tool, allowing comfortable work while maintaining standard hearing protection measures. Thanks to the inclusion of two high-capacity batteries in the kit, the user gains the continuous operation essential for larger renovation or construction projects.
