Professional precision measuring tool for industrial use (particularly on metal workpieces), totally different from DIY hand measuring one (like any carbon steel caliper, which is not good to measure metal workpieces bacause of the low hardness)

What is the most important factor for a precision measuring tool? Accuracy! All our finished calipers are inspected piece by piece to control the accuracy +/-0.001"/0.02mm. Though digital calipers are easy to read because of the screen, machinic ones (vernier calipers) are more reliable! This is why vernier calipers and dial ones still exist after digital ones appeared.

DURABLE: These rugged industrial-grade compasses are manufactured from heavy gauge steel.

CONVENIENT: Tip is accurately ground, works fine for outlining larger circles, and is easy to use.

NUMEROUS APPLICATION: Used for precisely scribing arcs and circles on projects and drawings such as woodworking and metal projects.

INDUSTRIAL GRADE: Professional compass for woodwork, metalwork, leatherwork, scribing, and geometry

USEFUL TOOL: For measuring distances, making technical drawings, navigation, drafting, and many more

HARD TIPS: Accurately ground tips sharp enough to draw lines on any workpiece clear and easy

High quality: Made of thick high-quality carbon steel with hardened and finely ground tips.

Measurement tool: It is a useful measurement transmission tool. Used in conjunction with a precision ruler to achieve the most accurate measurement transmission.

Accuracy: Forged steel legs have hardened points on the tip, which can be accurately marked.
