Precision Routing in Aluminium

The Onsrud 63-610 is a solid carbide router bit built for primary aluminium applications. Its uncoated 1/8 inch cutter diameter and up-spiral O-flute geometry target clean chip evacuation in non-ferrous metals. CNC operators and prototyping shops choose it when edge quality on thin aluminium sheet is the priority.

Up-Spiral O-Flute Chip Removal

The single specification that decides fit is the upcut O-flute spiral. It pulls chips upward and out of the cut, preventing re-cutting and heat build-up in soft aluminium. A downcut or straight flute would trap chips and degrade finish, so this geometry is the gatekeeper for the intended material.

Capacity for Thin-Wall Work

The 1/8 inch diameter handles detailed pockets, small-radius profiles and through-cuts in sheet stock up to moderate depth. It runs out when material thickness demands a larger shank for rigidity or when the machine spindle cannot hold such a small cutter securely. Heavier hogging or ferrous metals are outside its design envelope.

Questions about this item

What does the 1/8 inch cutter diameter mean when the bit is in a router?

The 1/8 inch cutter diameter sets the exact width of the cut made in the workpiece, so pockets, slots and profiles will all measure that size.

How does the O-flute upcut spiral design affect chip removal?

The O-flute upcut spiral pulls chips upward and out of the cut, which keeps the flute clear and reduces heat buildup in aluminium.

What shank size does this bit need to fit a collet?

The bit has a 1/2 inch shank, so it requires a 1/2 inch collet or an adapter that accepts that diameter.
