Mixing Drill Collomix KR 120 / M14 CX41631 — handheld mortar and paint mixer

The Collomix KR 120 handheld mixing drill with M14 spindle connection is a purpose-built tool for mixing mortars, paints, adhesives and other viscous building materials. Its compact design and standard M14 thread allow fast installation of compatible mixing paddles, enabling controlled manual mixing on site or in the workshop. The tool is intended for preparing cement-based mixes, plaster, paint batches and tile adhesives where a powerful, handheld mixer is preferred over stationary equipment.

Advantages

The Collomix KR 120 provides stable, continuous rotation suitable for a range of viscosities while remaining compact enough for manual handling in confined spaces. The M14 spindle ensures compatibility with a wide selection of industry-standard mixing paddles, so you can select the appropriate geometry for mortar, paint or adhesive. The design focuses on practical usability with straightforward mounting and operation, making it suitable for frequent changeovers and mobile jobsite work.

Suitable for

• Mixing cementitious mortars and plasters
• Preparing paint and coating batches
• Mixing tile adhesives and thinsets
• Small to medium volume on-site and workshop mixing tasks

Key specifications

• Handheld mixer form factor for manual operation
• M14 spindle connection for mounting mixing paddles
• Designed for use with viscous building materials such as mortar, plaster, paint and adhesive
• Compact design suitable for confined spaces and mobile jobsite use

How to use

Select a mixing paddle compatible with the M14 spindle and appropriate for the material to be mixed. Secure the paddle to the spindle according to the paddle manufacturer's instructions and ensure the connection is tightened. Place the paddle into the container with the material, start the drill at a low speed to avoid splashing, and gradually increase speed until a homogeneous mixture is achieved. Maintain a steady up-and-down motion where necessary to incorporate all material and monitor the mixer load to avoid overworking the motor.

Usage recommendations

Use paddles with the recommended geometry for the specific material (e.g., spiral or X-type for mortars, radial for paints), avoid prolonged continuous operation at maximum load, and wear appropriate personal protective equipment such as gloves and eye protection during mixing. For best results, follow material manufacturer instructions for water ratios and mixing times.
