Diamond Abrasive Antique Brush for Stone

A diamond abrasive brush is used to texture stone surfaces—most commonly to create antique, leather, satin, or anti-slip finishes.
Compared with “grinding for flatness,” brushing is about surface feel and micro-texture: opening pores slightly, softening sharp peaks, and blending light marks so the finish looks intentional rather than “reworked.”

Typical jobs it solves:

• Leather finish on granite/quartzite (uniform texture, less swirl)
• Antique/satin look on marble/limestone (reduce visible grind marks without over-polishing)
• Non-slip refinishing for flamed / bush-hammered surfaces
• Edge/cutout touch-up (especially with round brushes)

Yes—granite is one of the most common materials for diamond brushing, but the result depends on process control, not just the brush.

To get a good leather finish on granite:

• Start with a grit that can open the texture (too fine = no texture, too coarse = harsh scratches)

• Step up 2–4 levels to even out the feel and reduce random scratch patterns

• Keep pressure + feed + water stable (most “bad leather” finishes are actually instability problems)

What “good” looks like in production:

• Texture is even across the slab, including around harder mineral zones

• Surface feels soft, not “wire-scratched”

• You don’t need extra touch-up passes to hide swirl marks

Choose the brush geometry based on machine head compatibility + contact stability + where you are brushing.

Fickert

• Often used on continuous slab polishing lines

• Good when you need stable wide contact on slab faces

Frankfurt

• Also common on slab lines

• Known for steady tracking and consistent contact on many line setups

Round

• Best for edges, profiles, sink cutouts, spot repair

• Common for handheld grinders or edge machines; easy to control locally

If you tell me:

1）your machine head type, 2) whether you’re brushing slab face or edges,
I can map you to the most stable option immediately.

There isn’t one universal sequence, but there is a reliable rule:

• Antique finish = earlier stages define the texture more strongly

• Leather finish = balance texture definition + smoother touch

A practical way to set it up:

• Use 3–5 steps instead of “one brush does all”

• Avoid big grit jumps (big jumps = random scratch patterns that are hard to blend)

How to pick starting grit:

• If the stone is hard (granite/quartzite): start coarser to open texture efficiently

• If the stone is softer (marble/limestone): start less aggressive to avoid bruising and patchy gloss

Your brochure range 24#–1000# is a good full ladder; in real production most lines won’t use all of them—usually a selected subset.

Swirl marks usually come from uneven contact or process instability, not “brush quality” alone.

Checklist that actually fixes it:

• Contact: make sure the brush is fully contacting (no rocking / no partial edge contact)

• Water: keep flow stable; low water often causes heat + smearing

• Feed & pressure: don’t “force” a fine grit to do a coarse job

• Add a bridge step: if you jump too far between grits, add one intermediate grit

• Bristle density: too sparse can leave track patterns; too dense can overheat on resin-bound materials

If you tell me whether swirl appears more at center vs edges, I can pinpoint whether it’s head alignment/contact or grit jump.

They can blend light grinding marks and reduce the visibility of micro-scratches, especially when you use a sensible grit progression.
But they’re not a substitute for correcting deep tooling lines or major flatness issues.

Rule of thumb:

• Light marks / haze / micro-scratches → brushing can blend and “convert” the surface into a controlled texture

• Deep grooves / heavy lines → fix with the correct grinding step first, then brush to finish

This is why the best results come from thinking in a process chain (grind → refine → brush), not “one consumable solves everything.”

From your catalog: common options include snail holder (quick-change) and M14 thread.

Practical pairing:

• Polishing lines / standard heads: use the mount style that matches the line’s head system (often Fickert/Frankfurt interfaces)

• Handheld grinders & edge work: M14 is common for round brushes

• If changeover time matters, quick-change systems (like snail-type holders) help reduce downtime

If you send a photo of your current mount/head, I can confirm compatibility in one glance.

To quote accurately (and avoid wrong specs), I’d ask for these basics:

1. Stone type (granite / marble / limestone / quartzite / engineered stone)

2. Target finish (antique / leather / satin / non-slip)

3. Machine (polishing line / edge machine / handheld)

4. Brush type needed (Fickert / Frankfurt / Round)

5. Mount (snail holder / M14 / other)

6. Desired grit steps (or tell us current process and we propose a ladder)

Optional but very helpful:

• Slab size + throughput (m²/day)

• Current pain point (swirl, inconsistency, short life, cost per slab)

With that, you can quote per step and propose a predictable finishing cost plan instead of a vague “per brush” price.

Replace it when it stops producing a consistent texture efficiently—not only when it “looks worn.”

Production signs it’s time:

• Texture becomes patchy or uneven across the slab

• You need noticeably more passes to reach the same finish

• The brush starts “polishing” instead of cutting (surface gets unwanted gloss / smearing)

A simple, practical method:

• Track how many passes it normally takes on a stable stone batch

• If the same finish takes ~30–50% more passes, performance has dropped enough that cost per slab is rising
