Kolekcja: Diamond Laps & Discs

Professional diamond laps and discs for lapidary flat lap grinding and precision polishing. Features standard continuous-face diamond flat lap discs (6" to 24"), uniform nickel-electroplated full face laps (6" to 8"), and pattern-relieved diamond dot magnetic discs (6" to 24"). Available in magnetic quick-change, PSA peel-and-stick, master lap mounted, and plain backing options across grit grades from 45# coarse roughing to 3,000# optical pre-polishing. Fully compatible with all horizontal flat lap machines, rotary cabbing platens, and gemstone faceting equipment. Always use with continuous clean water coolant for maximum longevity and scratch-free surface finishes.

Frequently Asked Questions

• Q: What is the difference between flat lap discs, full face laps, and dot discs?
  A: Standard flat lap discs feature a continuous diamond plating layer designed for all-around flat lapping and stone shaping. Full face nickel-bonded laps provide an exceptionally uniform diamond distribution with tighter flatness tolerances, making them the standard choice for gemstone faceting. Dot discs use patterned diamond islands separated by relief channels, allowing swarf and water to evacuate freely for rapid cutting on hard stones and thick glass without hydroplaning or surface grab.
• Q: How do I match the lap disc diameter to my machine?
  A: Match the disc diameter directly to your machine's master platen. Standard benchtop hobby machines use 6" or 8" discs (often with 1/2" center arbors). Mid-size studio grinders use 10" or 12" discs. Production lapidary shops and glass studios use 14", 16", 18", or 24" discs.
• Q: Which backing type is recommended for my workflow?
  A: Magnetic backing is recommended for multi-grit sequences on a single machine platen, allowing you to swap from coarse roughing to fine smoothing in seconds without sticky residue. Choose PSA (adhesive) if you have dedicated single-grit platens or prefer lower per-disc costs. Master Lap backing is recommended for precision faceting machines requiring extreme flatness.
• Q: What grit progression is recommended for flattening a rough stone slab?
  A: Begin with 60# or 80# to quickly remove saw marks and achieve initial planarity. Step through 140# or 220# to eliminate deep roughing scratches, followed by 325# and 600# for surface refinement. Transition to 1,200# or 3,000# diamond smoothing pads for pre-polishing before moving to cerium or aluminum oxide compound on a felt pad.
• Q: Do these diamond lap discs require wet grinding?
  A: Yes. All diamond laps must run with a continuous water drip or mist coolant. Grinding dry will scorch delicate stones, instantly ruin electroplated diamond bonding, generate hazardous silica dust, and cause severe thermal disc warping.
