Rotary Milling Cutter Beta Tools 426MD-FA16 rounded arc 16 x 25 mm

Rotary milling cutter Beta Tools 426MD-FA16 rounded arc 16 x 25 mm is a solid cutting tool designed to produce concave radiused grooves and rounded contours. The cutter has a rounded arc profile with a cutting diameter of 16 mm and an overall cutting length of 25 mm, suitable for tasks that require smooth, consistent radiused channels. It is intended for use in milling machines and routers that accept the cutter's shank dimensions and speed range, and can be applied to both metalworking and woodworking operations when material-compatible cutting parameters are used.

Advantages

The rounded arc geometry provides uniform contact with the workpiece, reducing chatter and producing a consistent surface finish along the groove. Precision ground cutting edges maintain dimensional accuracy and help to extend tool life when used with appropriate feeds and speeds. The cutter’s compact profile allows access to confined areas and makes it suitable for profiling, deburring, and forming rounded channels without the need for multiple passes.

Suitable for

• Creating concave radiused grooves in wood, non-ferrous metals and some plastics
• Profiling and edge rounding on components
• Deburring and finishing curved channels
• Detail milling in confined or curved areas

Key specifications

• Cutting profile: rounded arc (concave)
• Cutting diameter: 16 mm
• Cutting length: 25 mm
• Material compatibility: suitable for wood, non-ferrous metals and compatible plastics when proper parameters are used
• Typical applications: profiling, deburring, channel forming

How to use

Mount the rotary milling cutter in a compatible router or milling machine with the correct shank holder and ensure secure clamping before starting. Select spindle speed and feed rate appropriate to the workpiece material, and perform a test pass on scrap material to confirm cutting settings. Use steady, controlled feeds to follow the intended path and avoid excessive radial immersion that could overload the cutter. Apply appropriate cooling or air blast where applicable for metalworking to evacuate chips and control heat.

Usage recommendations

For best results, match cutting speed and feed to the material: lower speeds and lighter feeds for harder non-ferrous metals, higher feeds for softer woods and plastics. Regularly inspect cutting edges for wear and recondition or replace the cutter when the finish or dimensional accuracy degrades. Use chip evacuation and, where necessary, lubricant or coolant when machining metals to prolong tool life and maintain consistent surface quality.
