Onsrud 56-654 Router Bit
The Onsrud 56-654 is a solid router bit designed for milling hard and soft plastics. It features a 1/2 inch cutter diameter and a straight O-flute geometry. The two-flute design incorporates a plunge point for direct entry into the workpiece. This accessory is built for precision routing applications in plastic materials.
Suited For Plastic Milling
This bit suits CNC operators and fabricators routing hard or soft plastic sheets where chip evacuation and finish quality matter. The O-flute geometry helps prevent chip welding in softer plastics. Buyers needing to mill aluminium, composites or wood should look at a different tool geometry. It is not intended for high-speed metal cutting or abrasive composite materials.
1/2 Inch Cutter Diameter
The 1/2 inch cutter diameter defines the cutting width and tool clearance for the job. This dimension determines the minimum internal radius achievable in a pocket. Verify that your collet or tool holder accepts this shank size before ordering. The 4 inch overall length sets the maximum reach for deep cavity work.

Questions about this item
How often will the 56-654 bit need resharpening when routing hard plastics?
Resharpening interval depends on feed rate and material hardness; inspect the two flutes regularly and regrind when edge wear reduces cut quality.
What limits continuous run time on the 56-654 end mill?
Heat buildup in the solid carbide body is the first limit; excessive temperature degrades the cutting edges and reduces tool life.
Does the 654 router bit generate excessive noise or heat during all-day CNC operation?
Normal spindle sound and moderate heat occur; use proper chip evacuation and coolant mist to keep temperatures stable during extended cuts.
