Application & material

This Onsrud 63-712 carbide routing end mill is built for hand-tool operations in hard plastic. The O-flute upcut geometry clears chips efficiently while the solid carbide construction resists wear during extended routing sessions. It suits CNC operators and fabricators who need clean edges in plastic sheet stock.

Who should choose another tool

Buyers cutting aluminium, composites or abrasive non-plastic materials should look elsewhere because the flute design and carbide grade are optimised for hard plastic only. Workshops that require downcut or compression spirals for double-sided laminates will not achieve the desired finish with this upcut profile.

Cutter diameter

The cutting diameter is 1/8 in, which determines the minimum inside radius and the step-over possible in a single pass. This dimension fixes the toolpath resolution and must match the programmed geometry before the job is started.

Questions about this item

How deep can the 1/8 inch carbide flute cut before heat limits sustained use?

The solid carbide O-flute upcut design evacuates chips efficiently in hard plastic, letting the 1/8 inch cutter run continuously until the tool length or machine rigidity becomes the limiting factor.

Does the carbide bit stay cool and quiet during all-day routing of hard plastic?

Carbide runs cooler than high-speed steel, and the upcut spiral pulls heat away with the chips, so noise and temperature remain low even during extended sessions.

What shank size must my router collet accept for this 63-712 bit?

The bit uses a standard 1/2 inch shank, so your router or CNC spindle needs a 1/2 inch collet or an appropriate reducer sleeve.
