Hole quality - high-density fiber core with a low natural resin level that does not contaminate the hole

Drill Wear - abrasive elements found in most other melamine products have been extracted to reduce drill wear created by the modified surface layer

Burr Prevention - accurate thickness tolerance is a perfect exit platform for the drill

Hole verification - a clean, white surface helps distinguish hole position.
