Flat chisel drill bit Makita B-64244 2 cm

The Makita B-64244 2 cm flat chisel drill bit is a professional-grade accessory designed for drilling and chiseling tasks where a wide, flat profile is required. Crafted to fit compatible rotary hammers and SDS-plus chucks, this flat chisel delivers a broad cutting edge for efficient material removal and reshaping. Its 2 cm diameter provides a balance between surface coverage and control, making it suitable for a variety of construction and renovation operations.

Advantages

This flat chisel drill bit offers high wear resistance and a consistent edge geometry that helps maintain cutting performance over time. The design reduces the need for frequent edge dressing and supports accurate, repeatable chiseling. Its compatibility with common pneumatic and electric hammer tools ensures straightforward installation and reliable engagement during heavy-duty use. The 2 cm width enables faster removal of plaster, tile adhesive, mortar and similar materials compared with narrower bits, while still allowing controlled precision where needed.

How to use

Fit the flat chisel securely into the hammer drill or rotary hammer according to the tool manufacturer's instructions. Select the appropriate hammering mode and hold the tool firmly with both hands. Position the chisel edge against the work surface at a shallow angle for removal of thin layers or at a steeper angle for deeper chiseling. Apply controlled pressure and allow the tool's hammer action to drive the chisel; avoid forcing the bit beyond its intended use. Periodically inspect the cutting edge and mounting connection for wear or loosening, and replace the bit when the edge becomes rounded or damaged to maintain efficient operation.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust mask or respirator when working with masonry materials. When removing tiles or mortar, work in short intervals to prevent overheating of the bit and the tool. Store the chisel in a dry place and protect the cutting edge from impacts to preserve geometry and service life.
