Professional Summary

• Manufacturer: Mungo (Switzerland)

• Model/Article: 1690013 (MIT-BN-H1 Series)

• Type: High-Density Nylon Hole Cleaning Brush

• Quantity: 1 piece

Technical Specifications

• Compatible Drill Hole Diameters ($d_0$): Multi-application sizing optimized for boreholes from 10 mm to 16 mm (and up to 20 mm for specific masonry setups).

• Total Brush Length ($L$): 300 mm (extended rod profile designed for deep-hole clearing).

• Material: High-density, heavy-duty industrial stiff nylon bristles twisted around a flexible yet strong braided steel wire core, finished with a manual control handle.

Key Benefits & Operating Features

• Fine Dust Sweeping Matrix: While steel wire brushes (MIT-BS series) are engineered to scrape and fracture hard concrete crust off the borehole walls, this high-density nylon brush acts as a fine broom. It captures and extracts sub-micron static dust particles that blowout pumps might leave behind.

• Resin System Synergy: Explicitly specified for use with Mungo's flagship injection mortars, including MIT-SE Plus (high-performance vinyl-ester) and MIT-SP (styrene-free polyester) systems, ensuring total compliance with European Technical Assessments (ETA) cleaning protocols.

• Flexible Core Resilience: The internal twisted steel spine allows for slight structural bending, making it easier to navigate angled drill holes or tight spaces without structural failure of the tool.

Application:

Universally specified on commercial and residential installation sites for the thorough cleaning of $\varnothing 10\text{ mm}$ to $\varnothing 16\text{ mm}$ holes in concrete, hollow brick, tuff, and aerated blocks. Used prior to injecting Mungo MIT chemical mortars to secure medium-duty threaded studs, sleeves, or electrical/HVAC hardware.
