Cutter, bearing and collet care:
Prolong the life of your equipment and save money by following these simple steps.
 Bearings: Before every box making session, place a drop of sewing machine oil in the bearing to keep it moist. Do not use a drying agent like CRC. The bearing is not sealed, so sawdust and grime build up over time. If you don’t keep the bearing clean, it will seize, causing damage to the cutter and your template.
 Cutters: Scrub the cutter blades and the outside surface of the bearing with a toothbrush to remove resin and dirt build-up.
 Collet: Clean the router collet in the same way, placing a small drop of oil inside the collet to dissolve resin build-up.
 Grub screws: Regularly check that the grub screw in the side of the cutter has not vibrated loose. Alternatively, use a product like ‘Loctite’ to fix the grub screw in place. Hint: to glue in a grub screw, do it over a light coloured cloth on a table. Position the screw hole over the flat edge on the cutter housing. Place a small drop of ‘Loctite’ in the hole and screw in the grub screw.
All Gifkins Dovetail cutters are designed for use in a table mounted router, and should not be used in a hand held router. We don’t guarantee cutters against breaking. The spiral cutter in particular, has a fine tip and should always be used in the table with a fence.
Take extra care to note the feed direction of the rebate cutter. With all cutting operations, the feed direction is opposite to the direction of motion of the cutting tips (i.e. opposite the direction of the tips as they enter the work piece).
