3-Point Caliper 5-40mm x 0.05mm

3-point vernier caliper designed for measuring 3-edged tools (e.g., reamers, drills, milling cutters) and odd-fluted cylindrical parts. Ensures accurate major diameter (MR) measurements where standard calipers fail.

Key Features:

• Range: 5–40mm (0.2–1.57")
• Resolution: 0.05mm (0.002")
• Three-Point Contact: Self-centering design for precise MR diameter of 3-flute tools.
• Stainless Steel Jaws: Wear-resistant for long-term reliability.
• Vernier Scale: No battery dependency – ideal for workshop environments.
• Locking Screw: Secures measurements without slippage.

Typical Applications:

• Tool grinding (reamers, end mills, countersinks)
• Quality control of odd-fluted cutting tools
• Machining and resharpening operations
