What are the specifications and models of electric hammer drill bits?
The model of impact drill is generally expressed by the diameter of the drill bit. There are many models such as 6mm, 8mmm, 10mm, 12mm, 14mm, 16mm, etc. Different models are suitable for different scenarios. They can be based on the work object and hole diameter, processing materials, and operations. Choose the appropriate model of impact drill according to the environment. When looking at the specification table of impact drill bits, just focus on the blade length, shank diameter, and pattern of the impact drill. Let’s take a look at the models of impact drills. 1. How many types of impact drill bits are there?
When purchasing an impact drill, you need to choose an appropriate model of impact drill based on the job requirements. The models of impact drills are generally distinguished by the diameter of the drill bit.
Common types of impact drills on the market include the following models: 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 20mm, 24mm, 26mm, 28mm, etc. Different types of impact drills have certain differences in parameters and are suitable for use scenarios. There are differences too.
- How to choose the appropriate impact drill model
When choosing an impact drill model, you mainly choose a model based on construction needs. You can choose from the following three aspects: - Select according to the work object and hole diameter.
When decorating indoors and arranging electrical appliances, nylon expansion bolts are generally used. The hole diameter is 6 to 12 mm, and impact drills of 10 and 12 mm specifications should be used; while in building construction, water and electricity installation, and exterior wall decoration, M8 to M14 mm metal is generally used. For expansion bolts, the hole diameter is between 12 and 20 mm, and an impact drill with 16 and 20 mm specifications should be used. - Select according to processing materials
- The 12mm size electric impact drill has a high impact frequency and is suitable for processing brittle materials, such as ceramic tiles, red bricks and other products. 16. The 20mm size impact drill has large output power and torque and is suitable for drilling holes in red bricks and lightweight concrete.
- Choose according to the working environment
10.12mm impact electric drills can be operated with one hand and are suitable for climbing and drilling upwards. 16. The 20mm size impact electric drill is equipped with a side handle and a drilling depth scale, which can be operated with both hands and is suitable for drilling holes on the ground and sides. - How to read the specification and model table of impact drill bits
- Blade length
In the impact drill bit specification table, the relevant blade lengths are marked for different models. The depths that can be reached by different blade lengths are different, so the required length needs to be selected according to actual needs. Failure to reach the length that the impact drill bit can reach will affect the progress and even cause damage to the drill bit. - Shank diameter
The length of the handle diameter is also a detail that must be paid attention to when selecting model specifications. The handle diameters for different specifications and models are sometimes the same and some are different, so you need to choose carefully. For example, if the blade diameter is 0.4 and 0.5, the handle diameter of these two is the same. And if the blade diameter is 0.6 or 0.7, then the handle diameter is 3.5. - Impact drill models and patterns
Different models of impact drills are designed with different patterns. This will also be reflected in some relatively complete model specification tables. Common patterns include twist metal drill bit design, flat-head blunt drill pattern design and four-cut head design. The impact strength and effect achieved by different patterns are completely different, so you must choose the one that suits your needs. drill bits and models. For example, if it is used to drill ceramic tiles, you can choose a drill bit with a four-cut head; if it is used to drill hard wood, you can choose a twist metal-head drill bit. Generally speaking, twist-shaped metal drill bits are the most common.
