About This

• COAXIAL CENTERING PRECISION: 0.0005" RESOLUTION FOR ZERO-ERROR ALIGNMENT – This Co-Ax indicator uses a precision lever mechanism to translate workpiece center position directly into dial pointer displacement, giving you reliable, repeatable center-finding with 0.0005" (0.01mm) resolution across a 0–0.15" range. Whether dialing in a lathe chuck, boring mill spindle, or CNC vise, you get accurate alignment data on every rotation — no guesswork, no re-cuts
• FACE-TRACKING DESIGN: DIAL ALWAYS FACES YOU DURING SPINDLE ROTATION – Unlike standard dial indicators that spin with the spindle (forcing you to chase the reading), this coaxial indicator keeps the dial face stationary and operator-facing throughout the full 360° spindle rotation. Read your runout values continuously without stopping the spindle — a critical advantage for efficient production floor use
• MEASURES INTERNAL AND EXTERNAL BORES: 5/32" TO 4-1/4" CAPACITY – Switch between internal bore centering (5/32" to 4-1/4" dia.) and external diameter alignment (0 to 4-1/4" dia.) simply by swapping the included feeler. The 3/8" (9.5mm) clamping shank fits standard milling machine spindles, CNC machining centers, and boring mills without adapters
• WORKS AT ANY ANGLE FOR CNC,METALWORKING & WOODWORKING – Operate this coaxial indicator at any angle from horizontal to vertical:▸CNC Milling: Precisely center round stock and irregular workpieces in your vise▸Lathe / Boring Mill: Align bore centerlines with spindle axis for accurate turning operations▸Metalworking: Verify concentricity on shafts,flanges,and bearing seats▸Woodworking & Laser: Center workpieces on CNC routers and laser engravers for repeatable setupsMax recommended spindle speed: 100 RPM
• COMPLETE 11-PIECE SET, READY TO USE – Everything you need is included: 1x coaxial centering indicator, 1x restraint rod, 1x center plug gauge, 6x feelers (3 straight + 3 bent for versatile bore access), 2x wrenches, user manual, and a protective storage case. The robust construction supports continuous precision use.Show Your Love with a Meaningful Gift for Dad, Grandpa and Family Members
