Betonimylly Graphite 58GE129

The Graphite 58GE129 concrete mixer is a cordless, brushless double mixer designed for efficient mixing of cement, plaster, paint, ordinary plaster and self-levelling screed. Powered by Graphite's Energy+ 18V battery system (battery not included), it delivers two speed ranges for controlled mixing and is supplied with two mixing paddles. The design emphasizes low weight and portability, with an overall weight of 3.8 kg and a compact mixing depth of 870 mm, making it suitable for site work and renovation tasks where mobility and easy handling are required.

Advantages

The brushless motor offers higher efficiency and reduced maintenance compared with brushed designs, while the two selectable speed ranges (250–400 rpm and 350–650 rpm) provide flexibility across different materials and viscosities. Self-clamping handles and rubberised grips increase user stability and control during operation. Supplied with two agitators, the tool adapts to a range of mixing tasks. The lightweight construction improves transport and reduces operator fatigue during prolonged use.

Suitable for

• Mixing cement and mortar for small to medium construction jobs
• Preparing plaster and finishing compounds
• Mixing paint and coatings
• Preparing self-levelling screed for floor leveling
• DIY renovation and professional site work requiring portable mixing

How to use

Install a compatible 18V Graphite Energy+ battery (battery sold separately) according to the manufacturer's instructions, select the appropriate agitator for the mixing material and secure it in the chuck or mounting. Position the mixer into the mixing container and start at the lower speed range to avoid splashing. Gradually increase speed as the mixture becomes homogeneous, using the higher speed range for thicker compounds when required. Maintain a steady grip on the self-clamping handles and keep the mixer at a slight angle to ensure consistent circulation of material within the container. After use, stop the motor, remove the battery, and clean the paddles and tool body to prevent material build-up.

Recommendations

For best results use Graphite 18V lithium-ion batteries with recommended capacity (for example 6 Ah) and choose the speed range according to material viscosity: lower speeds for thin paints and plasters, higher speeds for heavy cement mixes. Wear appropriate personal protective equipment including gloves and eye protection, and clean the mixing paddles immediately after use to prolong tool life.
