What to Know About Chisel Bits?

A chisel bit is a specific type of accessory that is used with hammer drills for cutting and demolishing hard materials like metal, stone, or ceramics. The main 5 types of chisel bits are flat, spade, tile, pointed, and channel chisel bits. These bits’ sizes range from 0.125 inches to 2 inches of width. Chisel bits are made of HSS, Carbon, solid carbide, and carbide-tipped steels.

A regular hammer drill is not able to be used as a chisel because its bit is moving with the chuck. In order to use a chisel in a hammer drill, you will need piston-based hammering system tools such as an electric demolition hammer, rotary drill, SDS plus, or SDS max.

What is a Chisel Bit?

A chisel bit is a specific type of accessory that is used with hammer drills for cutting and demolishing hard materials like metal, stone, or ceramics. Chisel bits are mainly 5 types such as pointed chisel bit, flat chisel bit, spade chisel bit, tile chisel it, and channel chisel bit. Chisel bits are made of high-strength materials such as high-speed steel (HSS), carbon tool steel, solid carbide, or carbide-tipped steel because they need to withstand high amounts of force and heat.

Chisel bits are used with SDS plus and SDS max hammer drills by activating the hammering action. Chisel bits are available is a wide range of sizes, ranging from 0.125 inches to 2 inches, but they can also be even larger for industrial-sized tasks. The size required depends on the level of detail needed in the work and the hardness of the material.

What are the Types of Chisel Bits?

A chisel is an attachment used to perform the role of a hammer drill successfully. Accordingly, there are several types of chisels that fit the function. Those are

  1. The pointed chisel
  2. The flat chisel
  3. The spade chisel
  4. The tile chisel
  5. The channel chisel

The shank of chisel shape is hex and made with steel, chromium steel, and premium chromium-vanadium steel.

TypeImportance of the Chisel
The pointed chiselThe tip chisel is the type of chisel that has the highest isolation force, as it has a pointed tip used to direct the full striking force of the drill to a small point.
The flat chiselHere the length of the flat tip corresponds exactly to the diameter of the shaft. Flat chisel fractures can be used to obtain precise control of the fracture lines of the material to be drilled and broken. One example is the ability to twist lines when applying cable ducts to a wall.
The spade chiselThe spade chisel has a wider tip. This tip extends beyond the thickness of the shaft and is used to transfer the striking power over a larger area of the material.
The tile chiselThe spade chisel has a flatter tip. The offset tip here is less physical exertion and helps the hammer drill handle more easily. The reason is that this chisel blade does not need to be held at an acute angle to the floor or masonry, so it is easy to use even for a long time.
The channel chiselLike flat chisel is a great tool for creating ducts for wall wiring or plumbing. The channel chisel ends are arranged in a semi-circular shape. Therefore the risk of rupture of the sides of the cable duct is greatly reduced on the one hand and the loose material on the other hand is easily removed.
The types of chisel and their importance

The chisel is made with few characteristics.

Those are;

  1. Manufactured with the heat-treat process.
  2. Necessary hardness
  3. Durability
  4. Long-term corrosion resistance

What are the Sizes of Chisel Bits Types?

When you look at the chisel on the market, you can see that the chisel type and the raw material of the product have manufacturer-specific sizes.

Point chisel9 inch (230mm)
Flat chisel0.82 X 9 inch (20.8 X 230mm); 
Cranked chisel1.58 X 9.84 inch (40 X 250mm)3 X 10 inch (75x250mm)
Scaling chisel3 X 12 inch
Spade chisel5-1/2 inch wide and rounded end 17-1/2 inch- This length is suitable to work fast.

Types of Chisels
The pointed chiselThe tip chisel is the type of chisel that has the highest isolation force, as it has a pointed tip used to direct the full striking force of the drill to a small point.
The flat chiselIt is the ability to twist lines when applying cable ducts to a wall.
The spade chiselThis is perfect for removing plaster from the masonry in large pieces over the entire surface.
The tile chiselThis shape allows the tile to be easily removed. If you need to remove a tile completely without damage and replace it, in such cases the chisel can be removed using a hammer drill. Therefore value addition has taken place to a hammer drill.
The channel chiselWe can use this type very efficiently to make lines or channels.
Chisels bits and uses

Which Hammer Drill Can be Used With Chisel?

The chisel can be used in

  1. Electric demolition hammer,
  2. Rotary drill
  3. SDS drills

Not every drill is capable of chiseling. Most of them have primary capacity. But the rotating hammer drill hammer creates a high impact force to perform secondary functions such as breaking concrete.

An electric demolition hammer cannot be used to drill a material because there is no bit rotation. Allows concrete to crack, cut, and chisel. Can be used to work on vertical surfaces also.

SDS plus and SDS max drill can be used. The SDS drill can use a wider size range of chisels. In which hammer drill we can use a chisel? SDS drill is a type of hammer drill. It is can use to do harder work.

How to Use Chisel Bit in Hammer Drill?

Follow these steps to use the chisel bit in the hammer drill.

  1. Select the right chisel type or size according to the work.
  2. If you want to lay cables or pipes in a wall or open holes in concrete, you should start with a small section to make a path for it.
  3. Removing debris from the cut surface can reduce friction and create a working process. Removal of debris from the work surface helps to extend the life of the drill and reduce friction.
  4. Switching the drill to the right mode is the most important step. The hammer drill has a hammering action because of the user must pay attention to switching the drill in the right mode.

How to Operate Hammer Drill with Chisel Bit?

You can operate the hammer drill with a chisel bit by following the below 2 steps.

  1. At first, a suitable chisel and drill machine must be picked for the work.
  2. Attach the chisel bit to the hammer drill. It must be placed it at a 45-degree angle to the edge of the tile or a suitable and easy place to chisel. You can activate the drill while in hammer mode. Turn the switch and lift the drill from the bottom to the top as it may damage you if it is so active.

What are the Pros and Cons of Chisel Bits?

These are the pros and cons of chisel drill bits.

Pros of using chisel bits in a hammer drill:

  1. Can break through hard materials, like masonry or concrete.
  2. Relatively inexpensive compared to other drill bit types.
  3. Ideal for demolition or removal projects.
  4. Typically durable and long-lasting.
  5. Able to make very detailed carvings or grooves in various materials.

Cons of using chisel bits in a hammer drill:

  1. May not be suitable for delicate or precision tasks.
  2. Using them improperly can lead to accidents.
  3. Not ideal for drilling into metal or wood materials.
  4. May require frequent sharpening for optimal efficacy.
  5. Can cause wear and tear on the hammer drill over time.

Can I Use Chisel Bit on Impact Drill?

Extremely yes. The impact drill can also use a chisel. There are also different chisels with different edges. These chisels are made from high-strength carbon steel. A round handle with two pits and two grooves is suitable for attaching to an impact drill.

  1. Sharp chisel
  2. Flat chisel
  3. Widened chisel

An impact drill is often more efficient than a hammer drill. Because its RPM is low and torque is high. That is why the shape of the drill bits is different; they take the shape of a hex. Most chisels on the market are for hammer drills.

These chisels can be used under powerful torsion resistance. Longer service life will even be under punishing use.

Hi, I am Tom Mackency. It has been 10 years that I have been working as a professional woodworker since 2013. I am really enjoying my carrier by creating many kinds of projects in my workshop. But mostly I like for home improvement projects. Home improvement and DIY projects are the most interesting things for me. More than that, the coolest things are power tools. Those are very precious and efficient than a decade ago. So I try to introduce so many things about power tools, woodworking, DIY projects, home improvement and many more interesting topics here.
