## Description

Cut clean, narrow profiles through PCB, fibreglass and carbon fibre with a 1 mm solid-carbide router built for abrasive composites.

Glass- and carbon-fibre laminates are hard on ordinary end mills: the fibres dull a sharp edge quickly, and stringy chips pack into the flute and fray the cut. A corn bit swaps the smooth helical flute for rows of small cutting teeth, named for their resemblance to a corn cob, that break the material into fine chips and clear them efficiently. The result is a cleaner edge on board outlines, slots and cut-outs.

The 1 mm diameter fits between closely packed components when routing a board free, and leaves internal corners with just a 0.5 mm radius. The 7 mm cutting length covers standard PCB stock with depth to spare for thicker composite sheet.

The 3.175 mm (1/8″) shank matches the rest of the Makera bit range, so it drops straight into the Carvera, the Carvera Air, or any desktop CNC or router with a 1/8″ collet. If you are using the Carvera's automatic tool changer, fit a bit collar at the correct height first.

### Features

- Cleaner edges in FR-4, fibreglass and carbon fibre, because the corn-cob tooth pattern breaks fibres into fine chips instead of tearing them.
- Tight 0.5 mm internal corners and narrow slots from the 1 mm cutting diameter, ideal for PCB outlines and small composite parts.
- Longer edge life in abrasive composites, thanks to titanium-nitride-coated solid carbide that stays hard and slick where uncoated tools wear quickly.
- Ten bits per pack, so a worn or snapped bit mid-project is a quick swap rather than a wait for stock.
- Makera publishes a starting feed and speed recipe for this exact bit in PCB and carbon fibre, so your first cut isn't a guess.
- A genuine Makera consumable, sized for Makera's own collets and bit collars, rather than a generic substitute.
