What polishing compound should I use with felt polishing tools?

Use diamond compound (14k-50k) for hard stones (Mohs 6.5+); cerium oxide slurry for glass and softer gems; tin oxide for delicate minerals like turquoise.

What is the primary difference between felt pads and felt wheels?

Felt pads are flat discs for flat lap machines and slab faces; felt wheels mount on bench grinder arbors to polish domed cabochons.

How do I select the right felt wheel size for my bench grinder?

Match wheel diameter (6" or 8") to your machine guard clearance and choose 20mm-50mm face width based on stone dimensions.

Should felt polishing tools be run wet, damp, or dry?

Run slightly damp with creamy compound slurry. Do not soak the wool or run dry, which can cause thermal scorching.

Which arbor bore options are available for felt wheels?

Standard bores include 1/2", 5/8", 3/4", 1", and 32mm to fit commercial grinder spindles.

Collection: Felt Polishing Tools

Professional felt polishing tools engineered for the final optical polishing stages of lapidary work, gemstone cabbing, glass edging, and jewelry finishing. Made from dense, pure natural wool felt, these tools retain polishing slurries and pastes uniformly, creating an optical mirror shine without orange-peel texture or facet rounding. Features magnetic-backed flat lap felt pads (6" to 24"), precision arbor-mounted cylindrical felt wheels (100mm to 250mm diameter, 20mm to 50mm face width), and 3mm/2.35mm shank-mounted miniature felt burs for flex-shaft detail polishing.

Frequently Asked Questions

Q: What polishing compound should I use with felt polishing tools?
A: For hard gemstones (Mohs 6.5+) such as agate, jasper, chalcedony, petrified wood, and corundum, apply diamond compound paste (typically 14,000 to 50,000 mesh) lightly onto the felt surface. For optical glass, fused silica, and softer silicates (Mohs 5 to 6.5), cerium oxide mixed with water into a creamy slurry provides an exceptional optical finish. For delicate, softer minerals like turquoise, malachite, or fluorite, use tin oxide or aluminum oxide to prevent surface damage.
Q: What is the primary difference between felt pads and felt wheels?
A: Felt pads are flat circular discs designed to sit on flat lap machines, allowing you to polish flat slab faces and the flat bases of cabochons. Felt wheels are cylindrical blocks that mount directly onto horizontal motor spindles, enabling you to work around domed cabochons and curved carvings.
Q: How do I select the right felt wheel size for my bench grinder?
A: Choose wheel diameter based on your grinder clearance: 150mm (6") for 6-inch bench grinders and 200mm (8") for 8-inch machines. For wide cabochons, select 40mm to 50mm widths to provide ample contact area; for smaller rings and delicate cabs, 20mm to 25mm face widths offer enhanced maneuverability.
Q: Should felt polishing tools be run wet, damp, or dry?
A: Always run felt tools slightly damp. Mix your polishing powder with just enough water to create a creamy paste, or apply diamond compound with a light drop of extender fluid. Never soak the felt in standing water, as saturated wool loses frictional efficiency, and never run completely dry to avoid thermal burning of both the stone and the felt.
Q: Which arbor bore options are available for felt wheels?
A: Felt wheels are supplied with precision bores in 1/2", 5/8", 3/4", 1", and 32mm configurations, matching standard commercial lapidary arbors and bench grinder drive shafts.
