Diamond Full Face Laps

Diamond Full Face Laps – Full-Surface Diamond Laps for Flat Lap Machines & Faceting

Diamond Full Face Laps feature a complete electroplated diamond surface across the entire lap face — providing uniform cutting action from the center to the outer edge of the lap. Unlike dot-pattern or segmented laps, the full-face diamond surface ensures consistent material removal at every point of contact, making these laps ideal for flat lap grinding, faceting, and precision surface finishing where uniform stock removal across the full lap face is required.

Frequently Asked Questions

  • Q: What is the difference between a full face lap and a dot-pattern lap?
    A: A full face lap has diamond coating across the entire surface — every point of contact cuts. A dot-pattern lap has open channels between the diamond dots that allow water and swarf to escape during grinding. Full face laps provide maximum cutting surface area; dot-pattern laps provide better coolant flow and swarf evacuation. Choose full face for maximum cutting efficiency; choose dot-pattern for better cooling on extended grinding sessions.
  • Q: Should diamond full face laps be used wet or dry?
    A: Wet use is strongly recommended. Keep water flowing over the lap during all grinding stages to cool the diamond surface, prevent glazing, and extend lap life. Most flat lap machines have a built-in water drip system — keep it running at all times during grinding.
