Additional Router Detail

Feed direction1. Bearing guided cutters

WT4603

Bearing guided cutters

F

• The arrow shows the direction of the feed for routing a profile on the edge of a piece of material using a bearing guided cutter.

• Material should be securely clamped or placed on a non-slip mat.

• The bearing will follow the profile of the edge of the material.


WT4603


• When viewed from above the feed direction for processing a moulding on the outside of a component will be in an anti-clockwise direction.

• Care needs to be taken when rolling around the corners or coming to the end of a straight as the router plate may not have as much support from the material underneath.


WT4603

Feed direction• Feed direction is critical to the

machining process.• The cutter rotation will be in a

clockwise direction.• To establish the correct feed

direction use the right hand rule shown in the photo.

• Place the thumb of the right hand against the edge to be processed.

• The back of your hand must be facing upwards.

• Extend the index finger as shown.• This finger will point in the direction

that you should feed the router.

WT4603

Calculating the offset

Template needs to account for the difference in diameter between the cutting bit and the guide bushing collar.


WT4603

Template & guide bearing cutter

When using a bearing guided trimming bit the template can be made to the exact shape or profile required.


WT4603

Routing at the corner

Cut end grain and let corners tear out

Long grain cut will remove torn-out material

Eliminating end grain tear out
