Routing End Mill for Soft Plastic

The Onsrud 63-760 is a solid carbide router bit designed for soft plastic applications. Its upcut O-flute spiral geometry evacuates chips efficiently during routing operations. This new tool suits CNC operators and fabricators who need clean cuts in plastic sheet or block stock.

Verify Shank and Diameter Compatibility

Confirm that your collet or tool holder accepts the 1/4 inch shank before ordering. Check that the 1/8 inch cutter diameter matches the detail resolution your toolpaths require. Ensure your spindle speed range suits carbide tooling in soft plastic to avoid melting or chipping.

Carbide Construction With Upcut Flute

Solid carbide body resists wear and holds edge geometry longer than high-speed steel in abrasive plastics. Upcut spiral pulls chips upward, clearing the slot but applying upward force on thin workpieces. Secure vacuum hold-down or mechanical clamping is essential to prevent part lift during cutting.

Questions about this item

Does the Onsrud 63-760 routing end mill arrive as a single solid carbide bit or are extra collets or accessories included?

The item ships as one solid carbide router bit with a 1/8 in cutter diameter, 1/4 in shank and 2 in overall length; no collets, wrenches or additional accessories are supplied.

How do the 1/8 in cutter diameter and 1/4 in shank of the 63-760 affect which jobs it suits best?

The 1/8 in cutter diameter is ideal for fine detail work and tight radii in soft plastics, while the 1/4 in shank fits standard CNC and hand-held router collets for rigid clamping.

What does the upcut O-flute geometry mean for chip evacuation and finish when routing soft plastic?

The upcut O-flute pulls chips upward and away from the cut, reducing re-cutting and heat buildup to leave a clean edge on soft plastic materials.
