Machinists and woodworkers, this HHIP convex cutter is seriously precision tooling at its best! The 1-1/4\ cutter diameter with 1/8\ radius is perfect for creating those smooth female half-circle profiles in your workpieces. Made from high-speed steel, this thing can handle both ferrous and non-ferrous materials without losing its edge quickly. The 3/4\ shank diameter is solid and fits securely in most milling machines and routers. At 3-1/2\ overall length, it gives you good reach without being unwieldy. The six teeth are precision ground to deliver a really clean finish - way better than you'd expect at this price point. I've used this for milling operations in both metal and wood projects, and it performs consistently well. The convex profile it creates is smooth and accurate every time. For hobbyists or professionals looking for quality cutting tools that won't break the bank, this HHIP cutter delivers solid performance. The construction feels durable and it's held up through multiple projects without showing significant wear. If you need a reliable convex cutter for your shop that produces professional results, this one is definitely worth adding to your toolkit. It's one of those tools that just works exactly as it should!
