• Premium Stainless Steel — Rust-Free & Logo Engraved: Each gauge blade is precision-cut from high-quality stainless steel, offering superior rust resistance and long-lasting durability. The smooth polished surface features a professionally engraved logo that won't fade or peel over time. Burr-free edges ensure a comfortable, safe grip during daily use.
• Custom Foam-Lined Case — No More Scratched Tools: Comes in a custom-molded carrying case with a precision-cut foam insert — each of the blades has its own dedicated slot, keeping them securely separated and scratch-free. The branded compact case keeps your workspace organized, makes it easy to grab-and-go for job site inspections, and doubles as a professional gift option for machinists and welders.
• Concave & Convex Dual-Design in Every Size: Every size in this set includes one concave and one convex gauge blade, so you can measure both inner fillet radii and outer corner radii with the same set — no need to buy separate tools. Ideal for tool inspection, weld profiling, template making, woodworking, and quality control checks. A versatile addition for professional machinists and DIY hobbyists.
