910 Series

The 910 Series is Sonic's solid carbide chamfer mill for deburring, chamfering, and countersinking in steel, titanium, and aluminum. Chamfer geometry produces a consistent angled edge in a single pass. The angle comes from the tool, not the program, so the chamfer matches part to part. Sonic lists the 910 by angle per side: 15°, 20°, 22.5°, 30°, and 45°. A 45° per side cutter is 90° included: it cuts a standard 45° edge chamfer or a 90° countersink for metric flat-head screws. You can also light-slot with it, and the slot comes out V-shaped with a flat at the bottom.

Sonic offers the 910 in AlTiN for steel, titanium alloys, and Inconel, and in TiB2 for aluminum and other non-ferrous materials. Sonic grinds every shank to h6 for precision holders and leaves a ground finish, not a polished one, so the shank resists slipping. Every tool is engraved with its lot number for traceability.
