⚡ At a Glance
- • Measuring Range: User reports indicate a wide practical span from small bores up to large diameters
- • Best for: Woodturners, hobbyists and bowl umpires needing internal diameter checks
- • Not ideal for: Precision metrology labs requiring certified calibration and micron-level readings
Straight-leg inside caliper with an 11 inch (272mm) total length for access into deeper bores. Hardened, finely ground stainless-steel tips provide wear resistance and long service life.
Accurate internal sizing – thanks to hardened, finely ground stainless-steel tips
Hardened tips have been finely ground to produce a consistent contact edge that resists wear during repeated use. Stainless-steel construction minimises deformation under normal workshop forces.
Reliable contact points help maintain measurement accuracy over time so matched tenons and bores fit more consistently. Less frequent re-grinding or replacement keeps workshop downtime to a minimum.
Wide practical coverage – with an 11-inch adjustable straight-leg design
Total length of 11 inches (272mm) allows the legs to reach deep into bowls, pipes, or turned work, while the adjustable spring mechanism sets and holds the span. Straight legs improve access into narrow or recessed openings.
Measure from small internal diameters to much larger openings without swapping tools, making it straightforward to check progressive fits during a turning session. Quick adjustments speed up repetitive checks.
Durable workshop performance – with stainless-steel construction and wear resistance
Stainless steel construction gives corrosion resistance and structural strength, while the hardened tips improve hardness and wear characteristics for a long service life.
Tool survives regular workshop knocks and occasional exposure to moisture, so replacements are less frequent. Users get a dependable implement that stands up to typical woodturning and pottery environments.
