⚡ At a Glance
- • Accuracy: High-precision centre marks on round bar, repeatable for consistent setups
- • Best for: Machinists, metalworkers and hobbyists working with round stock up to 75 mm
- • Not ideal for: Stock larger than 75 mm diameter or applications requiring flat-surface centring
Hardened and ground tool steel blade holds an accurate centre point for repeated use. Capacity covers round bar up to 3 inches or 75 millimetres for common workshop tasks.
Precise centre marks – Thanks to hardened and ground tool steel blade
Tempered and ground tool steel blade presents a sharp, wear-resistant centre point that keeps form across repeated contact. The hardened edge reduces deformation that would otherwise blur the mark.
Repeatable centre marks reduce setup time and help achieve cleaner finishes on turned parts, especially when working to tight concentricity requirements.
Durable performance – With tempered tool steel construction
Tool steel construction, combined with tempering and grinding, increases toughness while retaining edge hardness. The blade resists abrasion and the common knocks of a workshop environment.
Less frequent regrinding and dependable operation during coarse and general metalworking tasks, so downtime and maintenance are reduced.
Fits common stock sizes – With 3 in (75 mm) capacity
Rated capacity of three inches or 75 millimetres accommodates most small to medium round bar used in workshops. Users report better results when the finder is packed or shimmed correctly for secure contact.
Handles typical lathe stock without extra adapters and accepts packing to improve contact on uneven surfaces, giving accurate centre alignment for routine work.
