Flat chisel drill bit Makita B-64272 400 mm 1 pc

The Makita B-64272 flat chisel drill bit is a 400 mm single-piece accessory designed for drilling operations that require a flat chisel profile. Manufactured by Makita, this bit is intended for use with compatible hammer and rotary drilling tools where a flat, wide cut or chiselled hole is required. The 400 mm length provides extended reach for deeper penetrations while the single-piece construction supports stable handling during use.

Advantages

The flat chisel geometry delivers a consistent, controlled removal of material and helps produce clean, straight edges in masonry, concrete, and similar substrates. Its durable construction resists wear during repeated impacts and prolonged use. The 400 mm length reduces the need for multiple extensions when working at depth, and the one-piece design improves alignment and reduces play between components.

Suitable for

• Chiselling and making wide, flat openings in masonry and concrete
• Creating slots or channels for plumbing and electrical conduit
• Repair work requiring removal of material along a straight line
• Tasks where a robust, impact-resistant bit is required

How to use

Select a compatible hammer or rotary hammer that accepts the flat chisel shank and secure the bit according to the tool manufacturer's instructions. Position the chisel tip on the work surface, start the tool at low speed to establish contact, then apply steady pressure while operating the hammer function for efficient material removal. Maintain control of the tool to follow the intended cut line and avoid lateral forces that could damage the bit or workpiece. After use, inspect the chisel edge and clean debris to maintain performance.

Usage recommendations

Use appropriate personal protective equipment, including safety glasses, hearing protection, and gloves. Match the bit to a tool with suitable power and chisel function. Avoid excessive side loading and replace the bit if significant wear or damage to the cutting edge is observed.
