Carbide Upcut Router Bit

The Onsrud 63-620 is a solid carbide routing end mill designed for O-flute upcut spiral cutting. Its primary material application is aluminium, where the geometry promotes efficient chip evacuation. The tool is supplied new and carries a California Proposition 65 warning regarding reproductive harm.

Machinists Cutting Aluminium

This bit suits CNC operators and machinists producing clean upward chip flow in aluminium and similar non-ferrous metals. It is not intended for buyers who need a downcut action to hold down thin sheet material, nor for those requiring a multi-flute finisher for harder steels.

1/4 Inch Cutter Diameter

The cutting diameter is 1/4 inch, which determines the minimum internal radius and the toolholder size required. Select this dimension to match the programmed toolpath and the collet or chuck capacity of the machine.

Questions about this item

What shank interface does the Onsrud 63-620 use for router mounting?

The 63-620 has a 1/4 inch shank that fits standard router collets sized for that diameter.

What physical clearance does the 63-620 need inside a router collet?

The tool requires a collet that accepts a 1/4 inch shank with enough depth to seat the full shank length.

How is the Onsrud 63-620 installed in a router, and what step is often missed?

Insert the shank fully into the collet, tighten the collet nut securely, and verify the cutter does not bottom out against the collet body.
