RS Pro Radius Gauge Set Metric 16 Blades 0.25 mm, 0.5 mm 0.75 mm, 5.5 mm to 13 mm, 5 mm

The 683-0759 radius gauge set is a precision tool kit designed for quick and reliable measurement of internal and external radii across a broad range of curvature sizes. Supplied in a pen-knife style format with two leaf sets covering from approximately 0.75 mm to 13 mm, this stainless steel gauge set offers corrosion resistance, high durability, and clearly marked blade sizes for repeatable, accurate use. Ideal for quality control, machining inspection and fabrication processes where verifying fillet or round-over radii is critical.

Notable Advantages of the 683-0759 Radius Gauge Set

• Covers radius sizes from 0.75 mm to 5 mm in 0.25 mm increments, and 5.5 mm to 13 mm in 0.5 mm increments.
• Includes two rugged pen-knife style leaf sets: one 18-blade set, one 16-blade set.
• Stainless steel construction resists heat, wear and corrosion for industrial-grade longevity.
• Clear numeric size marking on each blade enables fast identification and measurement.
• Compact format simplifies storage, portability and on-the-bench or shop-floor use.

Engineered for Precision Radius Control

This radius gauge set is engineered to assist in accurate verification of component edge rounding, machined fillets and formed curvature features. In industries like CNC machining, sheet-metal fabrication and injection-moulding, ensuring that radii meet specifications is essential to product fit, tooling life and final assembly integrity. The dual-leaf design provides a broad coverage range, and with finely graded increments (0.25 mm and 0.5 mm), the set offers both coarse and fine measurement capability.

Application Versatility of the Product

• Inspecting internal concave and external convex radii on machined parts, castings or moulds.
• Verifying fillet radius compliance on fabricated sheet-metal, structural frames or enclosure corners.
• Quality control in automotive, aerospace, and general manufacturing processes.
• Tool-making, mould maintenance and design verification of rounded features.
• On-site maintenance or production line checks.
• Prototyping or repair workshops.
