Flat chisel drill bit Makita A-30483

The Makita A-30483 flat chisel drill bit is a 200 mm accessory designed for use with rotary hammers. It combines a flat, sharpened chisel face with a robust shank to provide efficient material removal, controlled chiseling and precise edge work. Constructed to meet common professional demands, this chisel bit is suitable for breaking, trimming and shaping masonry, concrete and similar building materials where a flat-faced tool is required.

Advantages

The flat chisel design delivers a consistent cutting profile and concentrates impact energy along a wide edge for faster removal of material compared with tapered points. Its 200 mm length gives a balance of reach and control for overhead or recessed work while maintaining rigidity under hammering action. The hardened working tip and sturdy shank reduce deformation and wear, improving lifetime and maintaining cutting performance over repeated use.

Suitable for

• Removing tile adhesive and mortar joints
• Cutting and trimming concrete and masonry surfaces
• Creating channels or recesses for pipes and conduits
• Chipping away protruding concrete or render

Key specifications

• Tool type: flat chisel drill bit for rotary hammers
• Overall length: 200 mm
• Working end: flat chisel face for wide material removal
• Material: hardened steel tip and reinforced shank (manufacturer standard)
• Connection: compatible with standard SDS-max/SDS-plus style rotary hammer chucks where applicable (check tool compatibility)

How to use

Install the chisel bit into the rotary hammer according to the tool manufacturer's instructions, ensuring the bit is fully seated and locked. Select the hammer or hammer-only mode appropriate for chiseling; if the tool offers adjustable power or impact settings, start at a lower setting to position the chisel then increase as needed. Hold the tool steadily with both hands, apply controlled pressure and let the hammer action perform the cutting. For extended work, periodically withdraw the bit to clear chips and inspect the tip condition. Always disconnect power before changing accessories.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust control measures when chiseling masonry or concrete. Match the chisel face width and length to the task to avoid excessive stress on the bit or tool. Replace the bit when the chisel edge becomes rounded or the shank shows visible wear to maintain efficient and safe operation.
