Drilling into a standard granite surface plate requires proper tools and techniques to ensure precision and avoid damaging the work surface. Here are the recommended methods:
Method 1 – Using an Electric Hammer
Start the drilling process slowly with an electric hammer, similar to drilling into concrete. For larger openings, use a special core hole saw. If cutting is required, a marble cutting machine equipped with a diamond saw blade is recommended. For surface grinding or finishing, an angle grinder can be used.
Method 2 – Using a Diamond Drill
When drilling holes in granite, a diamond-tipped drill bit is the preferred choice for its hardness and precision.
-
For holes with a diameter below 50 mm, a handheld diamond drill is sufficient.
-
For larger holes, use a bench-mounted diamond drilling machine to achieve cleaner cuts and better accuracy.
Advantages of Granite Surface Plates
Granite surface plates offer several benefits over cast iron alternatives:
-
Rust-proof & non-magnetic – No corrosion and no magnetic interference.
-
Superior precision – Higher measurement accuracy and better wear resistance.
-
Dimensional stability – No deformation, suitable for various environments.
-
Smooth operation – Measurement movements are stable without sticking or drag.
-
Damage tolerance – Minor scratches or dents on the surface do not affect measurement accuracy.
These properties make granite surface plates an exceptional choice for industrial metrology, precision machining, and laboratory testing.
