Our no-hole 360 grit Diamond Lap with dimensions of roughly 8 inches, and a weight of just about 0.6 lb. Crafted from a sturdy steel base with electroplated diamonds. The 360 grit is a great choice. Not too coarse to heavily scratch your cabochons, yet rough enough to flatten the back

Specially designed for cabbing machines, it's also versatile enough to be used with flat lap machines without an arbor hole such as the KNC8 and HP CB8, given the correct backing disc. Each Diamond Lap comes with a Pressure-Sensitive Adhesive (PSA) backing for easy installation - simply peel and stick onto your desired disc. Remember, it's designed for use with water cooling as a lubricant. The electroplated method ensures a consistent distribution of diamonds for a smooth grind every time, whether you're a hobbyist or a professional, making it a standout choice for precision and detail in your work.
