HP low-speed SK-2/4 silicone bonded abrasive polishers feature four progressive color-coded grit grades and diversified tapered bullet profiles. Custom-made for full-stage rough trimming to mirror gloss finishing of flexible acrylic removable denture bases in professional dental prosthetic labs.

SK-2/4 Series are professional low-speed HP polishing burs with silicone bonded abrasives, uniquely developed to tackle processing difficulties of flexible acrylic resin removable dentures. Different from universal polishers, its customized silicone bonding matrix firmly wraps evenly graded mineral abrasive grains, delivering controllable low-friction cutting force. Flexible acrylic denture bases are highly sensitive to heat, easily melted, bubbled, torn or permanently deformed under excessive grinding heat or rigid abrasives; this silicone composite formula effectively lowers thermal buildup while maintaining stable cutting efficiency.

Each polisher adopts an integrated stainless steel HP shank and compression-molded silicone abrasive body. Precision press-fit assembly achieves ultra-high concentricity, eliminating rotational wobble, uneven abrasion and localized overheating during long continuous operation. Four distinct color-marked grit grades form a seamless sequential finishing workflow. A full range of tapered, pointed, bullet and rounded tip shapes fits all denture anatomical structures: buccal/lingual flanges, undercut recesses, marginal borders, occlusal surfaces and palatal base planes.

1. Extra Coarse (Dark Brown Body, SK2121 / SK4001 Series)

2. Coarse (Black Body, SK2122 / SK4012 Series)

• Abrasion strength: Heavy-duty intermediate cutting
• Core function: Eliminate deep scratch marks left by extra coarse grit, flatten uneven flange surfaces, shape primary marginal contours
• Safe operating RPM: 20000–30000 RPM
• Packaging: 12pcs small trial pack / 100pcs bulk wholesale pack
• Ideal application: Bulk smoothing for standard flexible denture bodies

3. Mid-Coarse (Green Body, SK2123 / SK4013 Series)

• Abrasion strength: Balanced mild buffing power

• Safe operating RPM: 10000–20000 RPM
• Packaging: 12pcs small trial pack / 100pcs bulk wholesale pack
• Ideal application: Pre-finishing for visible aesthetic denture surfaces

4. Extra Fine (Beige Off-White Body, SK2125 / SK4015 Series)

• Abrasion strength: Ultra-gentle fine buffing
• Core function: Produce scratch-free mirror-level final gloss finish, reduce reliance on extra polishing paste for high-aesthetic dentures
• Safe operating RPM: 10000–12000 RPM
• Packaging: 12pcs small trial pack / 100pcs bulk wholesale pack
• Ideal application: Final gloss polishing for thin translucent flexible resin dentures

All profiles feature ergonomic tapered, pointed and bullet outlines optimized for curved denture anatomy, with standardized dimensions (Diameter * Length mm):

1. Slim Pointed Cone (SK2121/2122/2123/2125): Mini sizes 4*12, 6*16 for tiny interproximal gaps, narrow undercut crevices and delicate marginal trimming
2. Medium Bullet Cone (SK2141/2142/2143/2145): Medium sizes 10*20, 10*24 for wide flange and palatal large-area smoothing
3. Large Rounded Bullet (SK4001/4012/4013/4015): Oversized sizes 13*20,14*17,15*17 for full denture base bulk contour shaping and broad occlusal surface buffing

   Each rounded tip prevents sharp-edge gouging that easily cuts thin flexible resin layers.

1. Shank Standard: Universal HP low-speed solid stainless steel shank, compatible with over 95% of mainstream global dental lab low-speed grinding handpieces, no extra adapter required
2. Production Certification: Mass production complies with ISO 652 international dental abrasive safety standards; every batch undergoes centrifugal fracture resistance testing at maximum rated RPM
3. OEM Customization Support: Private brand laser engraving on steel shanks, custom mixed-grit mixed-shape assembly kits, personalized color printed retail packaging boxes, adjustable pack quantities for distributor private labeling
4. Three-Stage Pre-Shipment QC: 1) Shank concentricity runout test; 2) Silicone-abrasive bonding peel strength test; 3) Abrasive grain dispersion uniformity inspection before sealed packaging

1. Four complete progressive grit grades build an all-in-one workflow from heavy rough trimming to mirror ultra-fine gloss, removing the need to source separate resin polishing tool lines
2. Solid distinct color-coded silicone bodies enable instant visual grit identification, fully preventing irreversible scratch or melt damage to thin translucent flexible denture substrates caused by misused coarse grit
3. Custom heat-resistant silicone bonded matrix balances mild abrasion and low thermal output, greatly reducing risks of resin melting, blistering and warping unique to flexible acrylic denture materials
4. Multi-size tapered, bullet and rounded tip geometries access every hard-to-reach denture anatomy: undercuts, tight margins, thin flanges and large palatal planes without gouging thin resin walls
5. Clearly printed rated safe RPM values paired with ISO-certified structural tensile strength, significantly lowering hazards of silicone body fracture and flying fragments that cause hand and eye injuries to lab technicians
6. Standardized HP low-speed shank supports plug-and-play compatibility with nearly all global dental lab grinding machine models
7. Dual flexible packaging formats (12pcs small trial packs / 100pcs bulk wholesale packs) suit independent small private labs, chain laboratories and cross-border dental distributors
8. Evenly dispersed abrasive particles inside the silicone matrix maintain consistent polishing power from first use until full service-life depletion, with no sharp drop of cutting performance during operation

1. Consolidates lab consumable inventory: One SK series covers all flexible resin denture polishing procedures, cutting overhead costs of procurement, storage and stock management
2. Low scrap loss in production: Gentle silicone abrasive base avoids costly damage to high-value thin translucent flexible denture blanks often caused by rigid hard polishers
3. Stepwise graded polishing workflow shortens labor hours for secondary high-gloss paste buffing, boosting daily production efficiency of prosthetic labs
4. Intuitive color grading shortens training cycles for new technicians and reduces human error rates, stabilizing uniform denture finishing quality across all staff shifts
5. Restricted low safe RPM operation limits heat accumulation on heat-prone flexible acrylic, preserving long-term denture dimensional stability and surface aesthetic integrity
6. Durable cross-linked silicone bonding structure extends service life per polisher unit, lowering frequency of consumable reorders
7. Stable batch-to-batch manufacturing quality delivers identical polishing results for multi-workshop chain lab production networks
8. Compact standardized bullet shapes fit universal lab bur storage blocks, keeping workbenches tidy and protecting delicate silicone tips from impact breakage during storage and transportation
