company news about Step-by-Step Asphalt Drilling Guide: Wet vs. Dry Techniques

1. Preparation: Tools & Safety Gear

Drilling asphalt successfully requires a structured process. Before starting, assemble your "Pro Kit":

• Core Drill Machine: Handheld for shallow holes; stand-mounted for deep or high-volume jobs.

• Dust Control: Water feed system for wet drilling; HEPA vacuum (DeWalt DWV012) for dry drilling.

• PPE: Impact goggles, heavy-duty gloves, respirator, and hearing protection.

2. Site Prep & Surface Marking

1. Marking: Use bright spray paint or chalk.

2. GPR Check: Always use Ground-Penetrating Radar (GPR) or check utility maps to avoid hidden pipes.

3. Surface Cleaning: Sweep away loose gravel. If the surface is uneven, use a grinder to improve drill stability.

3. Choosing Your Method: Wet vs. Dry Drilling

How to Perform Wet Drilling

• Attach a water hose (aim for 1–2 liters per minute).

• Start slow (300–500 RPM) to create a guide groove.

• Increase to 800–1,200 RPM, letting the drill’s weight do the work.

How to Perform Dry Drilling

• Always attach a HEPA vacuum extractor to capture hazardous fine dust.

• Drill in bursts: 20–30 seconds of drilling, followed by a 10-second pause to cool the bit.

• If you hit a concrete base, switch to a diamond-tipped bit immediately.

4. Post-Drilling Maintenance

Clean your tools immediately after use. Rinse diamond bits to remove residue and store carbide bits in a dry case to prevent rust.
