Tungsten Carbide Burs

HP Dental Tungsten Carbide Grinding Bur is a professional lab trimming tool engineered for gypsum model shaping, acrylic denture adjustment, and titanium & CoCr alloy framework grinding. Fabricated from high-density solid tungsten carbide blanks and shaped via precision CNC flute machining, each bur delivers stable cutting performance and exceptional wear resistance to handle heavy daily dental lab workloads.

This product line categorizes cutting grades by flute density paired with colored marker rings for instant visual identification:

1. Cross Cut Standard (Blue Ring): Balanced cutting speed and smooth finishing, universally applicable to gypsum, regular acrylic and soft metal trimming; model series TC310-TC350
2. Cross Cut Fine (Red Ring): Tiny refined flutes leave minimal surface scratches, ideal for delicate margin finishing and thin acrylic veneer contouring; model series TC204-TC235
3. Cross Cut Coarse & Super-Coarse (Green Ring): Deep, wide flutes enable ultra-fast bulk material removal. Coarse grades suit thick metal and heavy gypsum trimming, while super-coarse variants are designed for rough grinding of solid metal blocks; model series TC401-TC503
4. Plain Cut Coarse & Standard: Single-direction smooth flutes operate with low vibration, perfect for precise adjustment of thin clasps and fragile metal components; models TC1007, TC903, TC904

All burs adopt a standard HP low-speed shank compatible with most mainstream dental lab low-speed handpieces without extra adapters. Every cutting edge undergoes strict deburring treatment to stop chipping, cracking or scratching of workpieces during grinding. Each unit passes concentricity testing to eliminate shaking at high rotation speeds. Apart from standard stocked sizes, OEM laser marking and customized packaging are available for global dental distributors and laboratories.

• High-density solid tungsten carbide substrate for long service life and outstanding fracture resistance
• Five cutting grade systems (fine/standard/coarse/super-coarse cross cut + plain cut) cover the full lab trimming workflow from rough grinding to precision finishing
• Color-coded identification rings accelerate operator sorting and grade selection
• Symmetrical flutes milled by precision CNC equipment ensure stable, low-vibration rotation
• Standard HP low-speed shank offers universal fit for all common dental lab grinding handpieces
• Burr-free sharp cutting edges protect gypsum, acrylic and metal workpieces from surface damage
• Complete size specifications labeled as head diameter * working length for accurate selection

1. Significantly reduces bur replacement frequency and lowers long-term lab consumable expenditure
2. Provides an all-in-one solution covering bulk rough grinding through high-precision fine finishing
3. Low-vibration rotation alleviates hand fatigue during extended continuous lab operations
4. Color grading prevents incorrect grit selection and costly workpiece scrap loss
5. Plug-and-play compatibility eliminates the need for extra adapters with existing HP handpiece equipment
6. Consistent batch-to-batch quality delivers uniform trimming results for mass lab production

1. Gypsum plaster models: Cross cut standard or super-coarse for rapid shape modification
2. Acrylic full/partial denture bases and temporary resin restorations: Cross cut fine or standard for smooth contour shaping
3. CoCr and Titanium alloy frameworks: Cross cut coarse or super-coarse for fast removal of excess metal material
4. Thin metal clasps and delicate marginal lines: Plain cut or cross cut fine for gentle, precise light trimming

1. High-purity tungsten carbide raw material provides far superior wear resistance compared to low-cost steel burs
2. Mature CNC flute manufacturing technology guarantees identical cutting geometry across every bur
3. Large factory stock enables fast global shipping, with flexible minimum order quantities for small lab trial orders
4. Full OEM customization: brand laser engraving, mixed-size assortment kits, bespoke box packaging
5. Professional dental consumable support team offers technical guidance for grit grade selection and optimal grinding speeds
6. Comprehensive pre-shipment quality control inspects concentricity, hardness and cutting sharpness for every batch

Q1: Which handpiece shank type fits these burs?

A: Standard HP low-speed shank, compatible with nearly all mainstream low-speed grinding handpieces used in dental labs.

Q2: Which cut type works best for final fine trimming of dentures?

A: Cross cut fine with red rings produces the smoothest acrylic surface prior to polishing procedures.

Q3: Can super-coarse cross cut burs trim thin metal clasps?

A: Not recommended. Plain cut or cross cut fine grades are safer to avoid deformation or fracture of thin clasp structures.

Q4: How can users maintain burs to extend their service life?

A: Brush away gypsum, acrylic and metal debris after each use, store in a dry environment, and avoid dropping to prevent tip breakage.
