BT30/BT40-H Run‑out Tester – Hand Crank Version (D132*141.5mm)

Non‑Contact, Friction‑Free Tool Run‑out Measurement

Accurate Tool Run‑out, No Contact Friction Errors

Measuring tool run‑out on the bench often introduces errors from bearing friction or uneven rotation. The BT30/BT40-H hand‑crank run‑out tester solves this – a hardened stainless steel and POM precision instrument that isolates the hand crank from the tool holder spindle. No contact, no friction, no induced inaccuracy. Just smooth, controlled rotation for reliable run‑out readings.

Core Benefits – Quick & Clear

• 
  Non‑Contact Transmission
  The hand crank shaft and the tool holder shaft operate without mechanical contact – eliminates friction‑induced positioning errors. Your measured run‑out reflects only the tool and holder, not the tester.
  
• 
  Smooth, Bidirectional Rotation
  Crank forward or backward freely. Large handle design allows slow, controlled rotation – ideal for observing dial indicator readings without jerking or skipping.
  
• 
  BT30/BT40 Dual Compatibility
  One tester accepts both BT30 and BT40 tapered tool holders. Swap between different shanks quickly without changing fixtures.
  
• 
  Precision Construction
  Hardened stainless steel critical components + POM (acetal) non‑contact drive elements. Lightweight at 4.5 kg, yet stable and wear‑resistant for daily shop floor use.
