Precision D4x28x50L PCB Corn End Mill — Titanium Coated Carbide Shank Cutter for CNC Routers Why you need it Consistent, clean cuts for PCB work and smallpart milling: the D4x28x50L geometry delivers accurate 4.0 mm cutting diameter with controlled cutting length for tracing, slotting, and profiling. Longer tool life and improved wear resistance from the titanium coating on a solid carbide body — reduces downtime and the frequency of replacements. Designed for CNC routers and milling machines that require a reliable shankmounted carbide end mill for finedetail work. Key attributes Model / Size: D4x28x50L (Cutting diameter 4.0 mm, cutting/flute length 28 mm, overall length 50 mm) Tool type: PCB Corn End Mill, shank milling cutter, carbide end mill Coating: Titanium coating for enhanced wear resistance and reduced adhesion Compatibility: Fits routers and milling machines that accept a 4 mm shank (standard collet systems for smalldiameter tooling) Use: Suitable for PCB routing, profiling, slotting, and general smallpart milling tasks in light, precision applications Main benefits Precision and repeatability: Ground carbide geometry maintains edge sharpness and concentricity for accurate traces and slots. Durability: Titanium coating extends life when cutting abrasive materials such as FR4 and common plastics. Reduced chip buildup: Coating helps reduce material adhesion on the flutes for cleaner cuts and smoother finishing. Versatile for smallscale work: Optimized length and diameter for detailed routing without excessive tool overhang. Typical applications / use cases PCB prototyping and isolation routing: Cleanly cut traces, remove copper between conductors, and mill slots for connectors on FR4 and similar board materials. Smallpart profiling and slotting: Precision cutting and profiling of plastic components, ABS parts, and small nonferrous parts where a 4 mm end mill is required. Model making and finedetail CNC work: Use in hobbyist and professional CNC routers for detailed engraving, contouring, and slot cutting where a durable carbide tip and titanium coating improve reliability. Technical specifications (as labeled) Designation: D4x28x50L Cutting diameter: 4.0 mm Flute/cutting length: 28 mm Overall length: 50 mm Material: Carbide end mill Coating: Titanium coated Tool style: PCB Corn End Mill, shank milling cutter for CNC router Usage notes Use appropriate collet/clamping for 4 mm shank to ensure concentricity and safety. Select feeds and speeds appropriate to the workpiece material and machine rigidity; avoid excessive axial loading. Inspect tool before use and when edge wear starts to affect cut quality. This D4x28x50L titaniumcoated carbide PCB Corn End Mill is built for accurate, repeatable, and durable performance in PCB and smallpart CNC milling tasks.
