3.175 mm Precision Cutting Bit — 17 mm Cutting Edge, 40 mm Total Length Key benefits Accurate sizing for predictable results: 3.175 mm shank and 3.175 mm cutting edge ensure a consistent cutting profile and straightforward tool setup. Stable performance in 1/8 inch (3.175 mm) collets: the matched shank-to-cutting diameter helps reduce runout and vibration for smoother finishes. Compact reach for detailed work: 17 mm cutting edge and 40 mm total length provide enough cutting depth while keeping the tool rigid and controllable. Important specifications Shank diameter (SD): 3.175 mm (approx) Cutting edge diameter (CED): 3.175 mm (approx) Cutting edge length (CEL): 17 mm (approx) Total length: 40 mm (approx) Function and compatibility Designed as a precision rotary cutting bit for small-format CNC machines, desktop routers, and rotary tools that accept a 1/8 in (3.175 mm) shank. Ideal for setups where tool change and collet compatibility matter; works with standard 3.175 mm collets and chucks. Performance notes Matched diameters simplify installation and alignment, helping maintain concentricity and reduce chatter on fine-detail cuts. Compact overall length balances cutting depth and stiffness to improve control in delicate operations. Practical use scenarios PCB prototyping and isolation routing where narrow, precise cuts are required for traces and slots. Model making and miniature carving for clean edges and fine detail on plastics, wood, and soft composite materials. Trim work and slotting on small assemblies in hobby CNC projects or rapid prototyping tasks. Usage tips Secure the shank in a properly sized 3.175 mm collet and check runout before use. Use appropriate speeds and feeds for the material being cut to prolong tool life and achieve the best finish. Specifications above are approximate and match the original product dimensions.
