Classic Silicone Grinding Head Polishing Grinding Head series

Classic Silicone Grinding Head is a multi-purpose graded abrasive tool built for global dental labs and jewelry processing workshops, fitted with standardized 2.35mm HP stainless steel shank compatible with all mainstream low-speed micromotor straight handpieces. Distinguished by 7 color-coded bodies, each shade matches exclusive grit and material application, eliminating guesswork for technicians and streamlining multi-material polishing workflows compared to single-function abrasive burs.

Manufactured with high-elastic medical-grade silicone bonded with uniform abrasive particles via precision curing molding, these grinding heads balance controlled cutting power and gentle buffering flexibility. The soft silicone matrix avoids surface scratches, micro-cracks and edge chipping on fragile porcelain, resin composite, and thin precious metal frameworks. Three core grit tiers—coarse for bulk trimming, medium for contour smoothing, fine for mirror high-gloss finish—cover full sequential finishing without frequent tool swapping.

Six dimensional configurations span compact to large capacity: 4.5*12mm,5*16mm,6*16.5mm,8*18mm,10*20mm,10*24mm. Each size is paired with calibrated recommended RPM to extend service life and optimize polishing effect; coarse/medium grades run at higher speeds (12000–15000 RPM), fine grades operate at lower 7000–10000 RPM to prevent overheating workpiece surfaces. Every bur undergoes concentricity QC to ensure low-vibration stable rotation during long continuous lab shifts.

Beyond dental restoration processing, this silicone series delivers reliable polishing for semi-precious/precious metal jewelry and precision hardware components. Consistent abrasive particle lock resists shedding, delivering long-term uniform performance and reducing recurring consumable replacement costs for both small custom studios and large-scale mass production facilities worldwide.

• Standard 2.35mm HP stainless steel shank, universal fit for dental lab low-speed handpieces
• 7 color-coded bodies with designated grit & material matching for easy identification
• 3 grit grades: Coarse / Medium / Fine for full trimming-smoothing-gloss workflow
• 6 size dimensions from mini 4.5*12mm to large 10*24mm for diverse surface areas
• Custom calibrated RPM ranges matched to grit size to protect workpieces and extend bur life
