A home-improvement tool locates the centre of round workpieces up to 38 mm diameter with reliable accuracy. Precise, ground blades reduce guesswork when setting up drills or lathes, so small projects finish neater. Is the AD INTERNATIONAL Centre Finder the right addition to a compact workshop?
⚡ At a Glance
- • Marking Precision: Precisely ground blades create consistent centre marks on round workpieces up to 38 mm diameter
- • Best for: Hobbyists and small-workshop users who need quick, repeatable centre location on small parts
- • Not ideal for: Large-diameter components or tasks requiring integrated measurement scales
Ground blades find the geometric centre of round items up to 38 mm across. Compact design suits simple centre marking in home and small workshop environments.
Accurate Centre Marks – thanks to precisely ground blades
Precisely ground blade edges contact the circumference and align so the intersection indicates the geometric centre of a round piece, with blade length allowing adequate reach for small parts. The mechanism relies on consistent blade flatness to avoid wobble during marking.
Reliable centre marks reduce setup errors when drilling or turning, saving rework and improving fit for small components.
Compact Reach for Small Parts – with 80 mm blade length
An 80 mm blade length gives enough span to engage round workpieces up to 38 mm diameter while keeping the tool compact. The short footprint makes handling easier for tight workspaces and small jigs.
Useful for hobby projects and small batches where oversized marking tools would be awkward to use.
Consistent Contact and Durability – with ground blade finish
Precisely ground finishes reduce burrs and deliver a uniform contact surface that resists deformation during normal layout work. Less edge irregularity means blade-to-workpiece contact stays consistent over multiple uses.
Maintains accuracy through repeated marking, so layout quality remains steady across several components.
✨ The 4 Key Reasons for AD INTERNATIONAL Centre Finder
