Up Down Cut 1 Flute Spiral (1+1 Compression)
Product Description
Up/down cut spiral router bits for a superior finish to double-sided laminates and veneered boards.
Up/down cut spirals are also referred to as compression bits.
1+1 Compression for 1 flute in up cut and 1 flute in down cut.
The design of the compression router bit is therefore aimed at best finish scenarios on double-sided boards, a popular choice of router bit for resizing or nesting cuts with CNC, the 1+1 is also great for small part cut-outs where feedrates will be slower and excessive heat build-up can be problematic.
Compression bits can also be useful in cutting shallow pockets and dados where applying a down shear action to the top edge during the shallow cut.
Low powered routers and spindles are also better suited to 1+1 compression bits versus 2+2 or 3+3 compression bits which require more power from the motor. Lighter frame CNC riggs will also benefit from 1+1 compression bits because less vibration will be the result versus 2+2 compression or 3+3 compression which are more aggressive cuts.
Chip clearance is directed inwards, towards that length of the bit where the up and down cut flutes overlap.
Compatible with CNC, table mounted routers and for hand held routing (portable routers).
