Product Description
SG-0/2 Series Silicone Polishers are premium HP low-speed abrasive tools exclusively engineered to meet two core finishing demands inside dental prosthetic labs: polishing soft precious gold and silver alloy cast restorations, and gentle buffing of heat-sensitive acrylic full & partial dentures. The high-elastic silicone matrix locks uniformly distributed abrasive grains, delivering mild, stable cutting power that cannot scratch delicate precious metal surfaces or melt thin acrylic resin during long-duration grinding.
Each polisher undergoes precise mold compression and tight shank press-fit assembly to achieve superior concentricity, eliminating rotational shake and uneven abrasion. Four distinct color-coded grit stages build a seamless step-by-step finishing pipeline, paired with multiple ergonomic profiles to access every complex anatomical contour on crowns, bridges, clasps and denture bases.

Key Features
- Four complete progressive grit grades form an all-in-one polishing workflow from heavy rough trimming to mirror ultra-fine gloss, removing the need to source separate tool sets for precious metal and resin denture processing
- Solid distinct color-coded polisher bodies enable instant visual grit identification, completely preventing damage caused by misapplying coarse grit on thin, delicate restorative substrates
- High-elastic flexible silicone bonding matrix delivers balanced mild abrasion: it will not gouge or scratch soft gold/silver precious alloys, and produces low friction heat to avoid acrylic melting, blistering or permanent deformation
- Four diversified geometric shapes cover every anatomical contour of dentures, crowns, bridges, clasps and implant frameworks, solving access limitations for narrow undercut and interproximal working areas
- Clearly printed safe RPM ratings on catalogs and packaging, paired with ISO-certified structural strength, greatly lowering risks of polisher fracture and flying fragment injury during daily lab operation
- Standardized HP low-speed shank enables plug-and-play compatibility with over 95% of global dental lab grinding equipment models
- Dual flexible packaging formats (12pcs small trial packs /100pcs bulk wholesale packs) suit both independent small private labs and large chain laboratories & international distributors
- Evenly dispersed abrasive grains inside the silicone matrix maintain consistent cutting and polishing performance from first use until full service-life depletion, with no sharp drop in grinding power mid-operation
Benefits
- Consolidates lab consumable inventory: A single SG series replaces separate precious metal and resin polishing tool lines, cutting procurement management, storage and ordering overhead costs
- Gentle silicone abrasive substrate drastically reduces costly restoration scrap: No irreversible damage to thin high-value gold crown margins or fragile translucent acrylic denture layers from overly rigid hard abrasive tools
- Stepwise graded polishing workflow shortens labor hours spent on final high-gloss paste buffing, boosting daily production output for high-volume prosthetic labs
- Intuitive color grading lowers new technician training time and human error rates, stabilizing uniform finishing quality across all lab staff shifts
- Restricted low safe RPM operation limits thermal buildup on resin and soft metal, preserving long-term restoration dimensional accuracy and surface structural integrity

FAQ
Q1: What shank type do all SG-0/2 polishers utilize?
A: Standard universal HP low-speed steel shank, compatible with over 95% of mainstream dental lab low-speed grinding handpiece brands globally; no extra adapter is required for installation.
Q2: Can black coarse grit polishers be applied directly to thin translucent aesthetic resin dentures?
A: Direct use on delicate aesthetic surfaces is not advised. Black coarse grit is only intended for heavy bulk excess trimming of thick resin bases; always follow the fixed sequence: Coarse → Mid-Coarse → Fine → Extra Fine to prevent over-grinding, deep permanent scratches and thermal resin deformation.
Q3: Are SG-0/2 silicone polishers interchangeable with RF-0/2 rubber polishers for CoCr and titanium base metal alloy processing?
A: They cannot be swapped. The SG line is engineered solely for soft precious metal and heat-sensitive acrylic resin; RF-0/2 rubber bonded polishers feature harder abrasive blends optimized for high-hardness CoCr, titanium and other base metal frameworks, delivering far faster stock removal for hard metal workpieces.
Q4: How should SG silicone polishers be stored to extend usable service life and prevent premature aging?
A: Seal and store in a cool, dry indoor ambient temperature, away from intense direct sunlight, high-temperature workshop zones and volatile chemical disinfectant fumes. Avoid heavy squeezing or bending the silicone abrasive body. After daily use, brush off residual metal and resin debris then fully air-dry before storage to stop embedded particles from dulling polishing performance.
Q5: Is it permitted to run rotation speeds higher than the printed maximum RPM to speed up polishing tasks?
A: This is strictly forbidden. Surpassing the rated maximum RPM creates excessive centrifugal force, which can crack and split the silicone body, launching sharp abrasive fragments that pose severe hand and eye injury risks to lab personnel. Excess speed also generates extreme heat that melts acrylic and warps thin precious metal structures.
Q6: Can we order custom mixed kits containing only selected shapes and grit grades matching our lab’s unique workflow?
A: Custom assembled kits are fully supported for OEM bulk orders. We can precisely combine disc, cylinder, arrow and taper shapes with your required grit grades, then package into branded boxed sets ready for immediate lab use or resale to clients.
