0.0312" (1/32") x .250" LOC TiN-Coated Diamond Flute PCB Router, Down-Cut, Fish Tail, 1/8" Shank | RS-110

RS-110 TiN-coated down-cut diamond flute PCB router features a 0.0312" (1/32" nominal) cutting diameter, .250" (6.35mm) length of cut, 1/8" shank, and 1-1/2" overall length. This solid carbide router combines diamond-cut flute geometry with a down-cut configuration for precision routing, profiling, and trimming of PCB laminates and abrasive composite materials.

The diamond flute geometry uses multiple small, intersecting cutting edges to provide a fine, controlled cutting action. This multi-edge pattern is well suited to machining FR-4, G10, fiberglass, and phenolic laminates, where minimizing edge chipping, fiber pull-out, and delamination is important.

Unlike conventional up-cut routers, the down-cut flute direction directs cutting forces toward the workpiece surface. This can help reduce lifting, fraying, and chipping along the top edge of layered materials. Because down-cut geometry directs debris downward, adequate chip clearance and appropriate cutting conditions are important.

The titanium nitride (TiN) coating provides a hard, wear-resistant surface that can help reduce friction and cutting-edge wear under suitable machining conditions. The fish tail tip is suited to PCB outline routing and profile cutting, while the extended .250" LOC provides additional cutting reach for applications requiring greater routing depth.

Machining Recommendations

Due to its small cutting diameter and extended .250" cutting length, this router requires careful control of spindle runout, feed rate, cutting depth, and workpiece support. Use a precision spindle and properly sized collet, secure the material firmly, and avoid excessive side loading to minimize tool deflection and breakage.

Down-cut consideration: The downward cutting action can help protect the top surface of laminated materials, but it may make debris evacuation more difficult in deeper slots or enclosed cuts. Use appropriate cutting depths and ensure that dust and debris can be removed effectively.

Important: Diamond flute refers to the multi-edge cutting geometry, not a diamond coating. TiN provides additional surface hardness but is not equivalent to diamond coating. For extended tool life when machining highly abrasive materials such as carbon fiber, consider diamond-coated tooling.
