Woodworking tooling for the professional

Combination Bit

This two flute cutter set produces moulded and scribed joints similar to the reversible T4200 series. The advantage of this set is that both parts of the joint are cut by simply adjusting the height of the cutter. This removes the problems associated with re-arranging the components on the arbor and the possible loss of shims etc. The set is available in 2 different profiles - Roman Ogee and Classical.
This method of construction produces a long glue line, giving a strong yet rapid method of constructing doors/panelling etc. This cutter is suitable for use in machines having a power output of 750 watts or more and is available in 1/2" shank sizes only. The cutters are suitable for use on timber between 18mm and 23mm in thickness.


Spare parts should be selected from this table and then ordered from the Bearings and Spares section of the catalogue.

APPLICATION DETAILS
These cutters need to be used in a table-mounted or overhead router or similar. The table will need a back fence and mitre slide to locate and hold the rails while they are being scribed. The face of the back fence should be aligned with the guide bearing on the cutter which will ensure the correct depth of cut. The mitre slide should be fitted with a timber face to act as a support to prevent breakout while the rail is being scribed. A backstop or other method of clamping should be arranged to prevent the rail being pushed back during the scribe operation.
Full instructions for use are supplied with the cutter.

SHANK LENGTH
With some combinations of routing machine and table a longer shank length can be necessary. If required an extended arbor can be ordered for this range of cutters increasing the "D" dimension to 58mm. This is only available in 1/2" shank and the part number is T4359.
