12 Pcs Angle Gauge Block Set

Q1: What are the different grades of gauge blocks?
A1: Gauge blocks come in different grades based on their precision and intended use. The main grades include:

• K Grade (Calibration Grade) – Highest accuracy, used in national metrology labs for primary calibration.
• Grade 00 – High precision, used in calibration labs and inspection rooms.
• Grade 0 – Precision measurement for tool rooms and high-accuracy machining.
• Grade 1 – General industrial inspection and high-precision manufacturing.
• Grade 2 – Standard for workshops and production environments.
• Workshop Grade – Lower precision, used for routine machine setup.

Q2: How to select the right gauge block set?    
A2: Selecting the right gauge block set depends on accuracy requirements, material, grade, and measurement system. Consider the following:

• Accuracy & Grade – Choose Grade K or 00 for laboratory calibration, Grade 0 for high-precision machining, and Grade 1 or 2 for general industrial use.
• Material – Steel is durable, ceramic resists corrosion, and tungsten carbide offers extreme wear resistance.
• Measurement System – Select metric (mm) or imperial (inch) based on your industry standards.
• Number of Blocks – A larger set (81 or 103 pieces) provides more versatility, while smaller sets (36 or 46 pieces) suit basic applications.

Q3: What is the difference between metric and imperial gauge block sets?
A3: The difference between metric and imperial gauge block sets lies in their unit of measurement and step increments. Metric gauge blocks use millimeters (mm) as the standard and typically follow increments such as 1.001 mm, 1.002 mm, etc. Imperial gauge blocks use inches, often following increments like 0.1001 inches, 0.1002 inches, and so on. While both sets serve the same purpose—precise length measurement and calibration—their use depends on the measurement system required for specific tools, industries, or regions.

Tips: How to maintain an angle gauge block set?

Proper maintenance of an angle gauge block set ensures accuracy, longevity, and reliable performance. Here are the key maintenance steps:

• Keep It Clean: Wipe after each use with a dry cloth; use isopropyl alcohol for stubborn residues.
• Prevent Rust and Corrosion: Apply anti-rust oil and store in a dry place with silica gel packs.
• Store Properly: Keep in a protective case and avoid stacking to prevent scratches.
• Handle with Care: Avoid dropping or hitting surfaces; use gloves or clean hands.
• Regular Calibration and Inspection: Check for wear and schedule professional calibration if used frequently.
• Avoid Extreme Temperatures: Keep at room temperature to prevent metal expansion.
