How To Use A Hole Drilling Bit

A Hole Drilling Bit is a cutting tool that is used to drill through or blind holes in solid materials and to redouble existing holes. Commonly used Hole Drilling bits include twist drill, flat drill, center drill, deep Hole drill and nesting drill, etc. Different hole Drilling bits have different functions. Here are the general steps and considerations for using a Hole Drilling Bit:

1. Select a proper Hole Drilling Bit: Select a proper drill bit based on the material to be drilled and the size of the hole. For example, for holes smaller than φ13.0mm, a straight shank drill is usually used; For larger diameter holes, a taper shank drill may be used.

2. Install the drill bit: Ensure that the connection between the drill bit and the main shaft of the electric drill is tight and not loose.

3. Align the Hole Drilling Bit with the position to be drilled, and ensure that the electric drill is perpendicular to the working surface.

4. Start drilling: Turn on the electric drill and slowly press the bit into the material. During the drilling process, the appropriate pressure and speed should be maintained to avoid being too fast or too slow.

5. Cooling and lubrication: During the drilling process, coolant or lubricating oil can be used to reduce friction and heat and extend the service life of the drill.

6. Check the size of the hole: After drilling, use a caliper or other measuring tool to check the size of the hole to ensure that it meets the requirements.

7. Clean up the working area: After drilling, remove metal chips and debris from the working area to keep the working environment clean.

When using the Hole Drilling Bit, you should also pay attention to the following:

• Before starting drilling, determine the thickness and hardness of the material to select the appropriate bit type and speed.

• For brittle materials or softer materials, lower rotational speeds and smaller feed speeds should be used.

• If resistance increases suddenly or the Hole Drilling Bit overheats during drilling, stop drilling immediately and check whether the bit is damaged or blocked.

• Regularly inspect and maintain drill and Hole Drilling bits to ensure they are in good working order.
