Factors such as resistance, power, and durability are among the most important in choosing an effective rechargeable tool. The Ronix 8901K mini angle grinder kit is produced to make you a professional user of cordless tools!

Ronix 8901K, 20V Brushless Mini Angle Grinder Kit:
The Ronix 8901K is equipped with a brushless motor. Compared to universal motors, brushless motors operate with a higher power-to-weight ratio, less heat and friction, more stable speed, and greater efficiency. The Ronix 8901K mini cordless angle grinder is built with a compact body to be your reliable companion during busy work hours. In this section, learn about the features of this efficient Ronix tool.

Motor and Mechanism:
A high-efficiency brushless 20V motor empowers this mini angle grinder. As their name suggests, Brushless motors use an electronic plate instead of a pair of carbon brushes in their internal structure. The absence of a carbon brush reduces the wear and tear of the engine and ensures four times longer lifetime. The motor of this mini-angle grinder has a no-load speed of up to 8500 RPM, rotates the 115mm cutting wheel with full power, covers a wide range of applications, and provides outstanding performance. The motor has an electronic current limiter system to protect the tool from current overload.

The gearbox of the Ronix 8901K enables heavy-duty application and a longer lifetime. This strong gearbox can generate an 8500 RPM no-load rotation speed.

Cutting Wheel:
The cutting wheel of the Ronix 8901K mini angle grinder kit has a maximum wheel diameter of 115mm. Ronix provided a wheel guard for the user’s protection and safety during the operations. The cutting wheel is also attached to an M14 spindle on the angle grinder. The bore diameter of the wheels is also 22.23mm. The cutting wheel has a tool-free adjustment system.

Ronix has always tried to strike a balance between comfort in handling and functionality. With its ergonomically designed and slim body, this tool is best suited to handle cutting and grinding operations in tight spaces and increase working performance. Ronix 8901K mini angle grinder guarantees outstanding performance and considerable power; nevertheless, it only weighs 1.65 kg. An auxiliary 2-position, anti-shock, and ergonomic side handle is built to provide all-day operator comfort, low fatigue, and additional control in different ranges of operator movement.

The ON/OFF switch and locking pin are the controlling keys of this mini angle grinder, both of which are anti-dust keys with the ability to prevent dust from entering the tool.
The locking pin is designed on the body of the gearbox and allows the user to easily replace the cutting wheel by keeping the shaft fixed, preventing it from moving and keeping it in the most stable position. The shaft’s locking process is done quickly by this key, and as a result, it affects the changing speed of the screen.

Direct Airflow System:
High temperatures can cause permanent damage to your battery and cordless tools during continuous, heavy-duty tasks. Ronix has developed an innovative cooling system for its mini angle grinder that directs sufficient airflow over the motor and cools it as much as possible. This direct airflow system also results in reliable performance and diverts dust away from vital components.

Soft-Start System:
The Ronix mini angle grinder has a soft-start technology that brings the machine up to full speed step by step. Even if you accidentally press the start button, the anti-restart function prevents the tool from starting.

The power source of 8901K is a 20V lithium-ion battery with a capacity of 4Ah. With its long life, this battery will always power your tool. The most significant advantage of the Ronix 89 Lasting Series is that the battery is compatible with all its members. So, you can run all your tools with just one battery. This battery has a charge indicator and can inform you of the battery status before it runs out in the middle of an operation. The fast-charging system in the charger provides optimum performance.

Accessories and Packaging:
The Ronix 8901K Brushless mini angle grinder kit is supplied in a Ronix BMC case and includes two 4Ah/20V batteries and a 2.2A charger.
