Soft plastic routing cutter

The Onsrud 63-768 is a solid carbide router bit designed for upward chip evacuation in soft plastics. Its O-flute upcut geometry clears swarf efficiently to reduce re-cutting and heat buildup. The 3/16 inch cutter diameter suits detailed profiling and slotting work. This new tool arrives ready for use in compatible collets.

The upcut action pulls chips away from the cut, making it a good fit for through-cuts and deep pockets where evacuation matters. Users who need a downcut or compression spiral to protect top-surface finish on laminated sheet should consider a different geometry. The single 3/16 inch size also limits this bit to one specific cutter diameter.

3/16 inch O-flute upcut carbide bit for soft

The defining specification is the O-flute upcut design paired with a 3/16 inch carbide cutter. That combination determines whether the tool matches the material, machine rigidity and finish requirements of the job. Verify collet compatibility and required cut depth before purchase.

Questions about this item

What shank diameter does the Onsrud 63-768 end mill need to fit my router collet?

The cutter diameter is 3/16 in, which typically matches a 3/16 in shank for standard collets.

How do I install the Onsrud 63-768 bit without damaging the carbide cutting edges?

Insert the shank fully into the collet, tighten securely, and avoid side loads during the first plunge to protect the O-flute geometry.

When should I replace the Onsrud 63-768 router bit based on wear?

Replace the bit when the upcut flutes show dull edges, chipping, or when cut quality on soft plastic degrades noticeably.
