Onsrud 11-06 Square End Double Edge Router Bit 3/8in Hss

Product Description

The ONSRUD 11-06 is a two-flute, square end, double edge router bit designed for routing and trimming operations in a wide range of plastic and thermoplastic materials. Built from high speed steel, it delivers consistent edge quality on materials that require clean, precise cuts. The bit features a 3/8-inch cutter diameter, a 1-inch length of cut, and a right-hand cutting direction. With a 2-1/2-inch overall length and a 3/8-inch shank diameter, it fits standard router collets used in CNC routers and handheld routing equipment. Machinists, CNC operators, and fabricators working in plastics production and signage use this bit as a reliable everyday tool.

This router bit is suited for use on a broad range of thermoplastic and extruded materials, including ABS, HDPE, polyvinyl chloride, polycarbonate, polyethylene, polypropylene, extruded acrylic, polystyrene, and UHMW. It is a practical choice for shops that process sheet plastics, fabricate enclosures, or produce routed signage panels. The straight flute geometry and square end profile make it well matched to profiling, slotting, and full-depth trimming passes in these materials.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the router or machining center powered down and locked out before changing tooling. Verify that the collet and collet nut are clean and in good condition before seating the shank. Follow the router or spindle manufacturer's guidelines for minimum shank insertion depth and collet torque. Always confirm spindle rotation direction matches the right-hand cutting geometry of this bit before running.
