Engineered for precision cylinder and bore work, this kit pairs a versatile digital indicator bore gauge set with a powerful 25000Rpm air die grinder. First, accurately measure bore diameters and depths 0.7-6" for machining, automotive, or CNC applications. Then, use the air grinder with multiple collets to perfectly polish, smooth edges, and deburr the finished surfaces. This integrated workflow ensures parts are measured to exact specifications and finished to a professional standard, saving time and guaranteeing quality from measurement to final touch.

  • 0.0005” Precision Deep Bore Gauge:XUNTOP digital bore gauge (0.7-6" dia./5-6" depth) delivers 0.0005" resolution & ≤0.5m/s response for micro-deviation checks.Ideal for engine cylinders, hydraulic systems, and aerospace components requiring ultra-precise bore measurements
  • Two-point Contact Probe: XUNTOP cylinder measurement tool features a precision two-point contact design (±0.005mm) with self-centering. Its hardened probe (HRC60+) and chrome-plated handle ensure wear resistance, while the all-metal locking system guarantees stability. Ideal for deep-bore (5"/6") and high-vibration applications
  • High-Contrast LCD & Zero-Setting: The digital bore gauge combines a high-contrast LCD for clear visibility in low-light conditions with instant mm/inch unit conversion, minimizing reading errors across measurement standards. Integrated with zero-setting function for rapid recalibration at any position, it eliminates manual adjustments and reduces operator fatigue
  • Powerful & Efficient Grinding:The straight pneumatic grinder is powered by compressed air, with a speed of up to 25000RPM and a working pressure of 90PSI, which can efficiently grind and facilitate the handling of larger and harder workpieces to reduce working time and costs
  • Rear Exhaust Design:XUNTOP air die grinder adopts rear-exhaust design, which ensures that the exhaust will not face the operator to protect your safety.Meanwhile, it can effectively reduce noise, vibration and dust generated into the tool and operation area during the work
