How to drill holes for highway guardrail materials

Firstly, be prepared for your own safety when drilling, such as wearing loose clothing or headgear, wearing protective gloves, and remembering that safety always comes first. Do not place the highway guardrail on your knees. What should you do if you drill down onto your legs? Maintaining safety and clamping the highway guardrail is also crucial. If not clamped, it may cause movement, rotation, and lifting during drilling, and in severe cases, it may cause damage or even self injury.

Mark the X point, which makes it easier to find the exact location where the highway guardrail wants to drill holes. Permanent markers can also be used to mark it, or center markers can be used to mark the position. If you are concerned that the drill bit may scratch the surface with debris during rotation, you can cover the marked area with heavy-duty tape.

When it is necessary to drill holes on the highway guardrail with a diameter of only 8mm, it is necessary to rotate the drilling on both sides. Unless a drilling machine is used, when the size exceeds these limits, it is likely that more than 8mm holes will be drilled. For some strict requirements, it may only be considered as scrap.
