What is SDS Chisel Bits?

SDS chisel bits are a type of SDS drill bit that has a sharp, angled tip that can chisel and break through hard materials like masonry and concrete. They are used with SDS rotary hammer drills that have a hammering mode or a rotary with a hammering mode. SDS chisel bits can be used for various tasks, such as demolition, channeling, scaling, and mortar raking.

What are the Different Types of SDS Chisel Bits?

There are different types of SDS chisel bits based on the shape and size of the tip and the shank. Some common types of SDS chisel bits are:

  • Flat chisel: This has a wide, flat tip that can remove large amounts of material quickly and efficiently.
  • Point chisel: This has a pointed tip that can penetrate and crack hard materials easily and precisely.
  • Tile chisel: This has a cranked or bent tip that can remove tiles without damaging the underlying surface.
  • Scutch comb chisel: This has a slot that can hold replaceable combs that can rake out mortar joints between bricks or stones.
  • Channelling chisel: This has a narrow, rectangular tip that can create channels or grooves in walls or floors for pipes or cables.
How to use SDS Chisel Bits?

To use SDS chisel bits, you need to follow these steps:

  • Choose the right SDS chisel bit for the material and the task you want to perform. There are different types of SDS chisel bits, such as flat chisel, point chisel, tile chisel, scutch comb chisel, and channelling chisel.
  • Set your SDS drill to hammer mode only or rotary with hammer mode, depending on the type of chiselling you want to do. The hammer mode will only provide more impact force without rotation, while the rotary with hammer mode will provide both impact and rotation for faster drilling and chiselling.
  • Secure the workpiece with clamps or a vice, if possible, to prevent it from moving or slipping while chiselling.
  • Insert the SDS chisel bit into the chuck of your SDS drill and ensure that it is securely locked in place. You can do this by placing the shank of the bit into the holder, and rotating it slightly to align the slots until you can push the bit in. The spring-loaded chuck will secure it without the need for additional tightening.
  • Position the SDS chisel bit at an appropriate angle to the workpiece and apply moderate pressure. For example, if you want to remove tiles, you can place the bit at a 45-degree angle and move it along the edge of the tile. If you want to create channels or grooves, you can place the bit perpendicular to the surface and move it along the desired path.
  • Monitor the chiselling progress and adjust the pressure and speed as needed. You can also use a depth stop or a tape measure to ensure that you chisel to the desired depth. If you encounter any resistance or obstruction, such as rebar or aggregate, you can increase the force or switch to rotary with hammer mode to break through it.
  • Remove the SDS chisel bit from the chuck by pulling it out or using a release mechanism if your drill has one. Clean the bit and store it properly for future use.
