Description

This tungsten carbide gauge block set is the benchmark precision calibration standard tool in dimensional metrology, used to calibrate vernier calipers, micrometers, dial indicators and all kinds of measuring fixtures, widely applied in mold manufacturing, precision grinding and quality inspection. Hoshing strictly produces in accordance with DIN 861 German industrial standard, with Grade 0 ultra-precision tolerance, far exceeding ordinary steel gauge blocks in wear resistance and service life.
  1. Premium Tungsten Carbide Material Core Advantage
    All gauge blanks are made of solid tungsten carbide alloy, featuring ultra-high hardness (HRC≥72), excellent wear resistance, anti-rust and anti-corrosion performance. Compared with steel gauge blocks, tungsten carbide material avoids dimensional deviation caused by long-term friction and oxidation, maintaining stable calibration accuracy for decades of heavy daily use.
  2. Grade 0 Ultra-Tight Precision Tolerance
    Strictly processed by multi-times precision grinding and cryogenic stabilization aging treatment, flatness, parallelism and length tolerance fully meet DIN 861 Grade 0 top-level standard. Each single block undergoes 100% laboratory precision inspection before delivery, guaranteeing reliable traceable calibration data for quality control.
  3. Multiple Complete Combination Specifications
    Rich set configurations to match different application scenarios:
  • Small 32pcs set: For basic student training and light daily calibration
  • Medium 46/87/103pcs sets: Standard configuration for general mold & hardware QC labs
  • Full 122pcs complete set: Full-range combination for professional metrology inspection rooms
    All combinations can be freely stacked and combined to achieve continuous length measurement from minimum to maximum range.
  1. Moisture-Proof Solid Wooden Storage Case
    Equipped with sealed solid wood storage box with shock-absorbing fixed slots, each gauge block has independent positioning card slot to prevent collision scratch. The wooden box isolates moisture and air, effectively protecting tungsten carbide blocks from damp environment oxidation. Every retail set is attached with a printed original factory inspection certificate recording each block’s actual measured error data.
  2. Complete Retail Global Shipping Configuration
    Each gauge block set is individually packed with outer shockproof carton, matched with full English product specification and operation guide. Support international express retail delivery, all inspection documents can be provided for customs clearance and third-party laboratory traceability verification.
