Panel Raiser - Double Cove router bit
The raised panel is captured in a groove made in the inside edge of the frame members. Panels are made slightly smaller than the available space within the frame to provide room for movement. Wood will expand and contract across the grain, and a wide panel made of solid wood could change width by up to 6mm, warping the door frame.
By allowing the wood panel to float, it can expand and contract without damaging the door. A typical panel would be cut to allow 5 mm between itself and the bottom of the groove in the frame.
A raised panel has a profile cut into its edge so that the panel surface is flush with or proud of the frame. Some popular profiles are the ogee, chamfer, and scoop or cove.
This router bit is for machining of traditional panels & frame doors with heavy duty routers mounted in fixed positions, either inverted or overhead. These Raised Panel cutters perform best at lower speeds. They are all suitable for use on natural timbers and MDF (medium density fibre board).
This router bit has a 6.35mm shank (shaft) that will fit most small or large routers with the correct size collet. Please ensure that you select a router bit with a shank (shaft) size that will fit into your router collet.
PRO-TECH router bits are manufactured in Taiwan.
Router Bit Maintenance
Fortunately, this is pretty easy. The best way to prolong the life of a router bit is to keep it clean. And what you need to do varies with the type of bit.
Note: Sharpening is extremely important too.
Bits with Bearings:
To clean bits with bearings, first, remove the bearing. Then clean the bit as you did with non-bearing bits.
It's important to remove the bearings because even though router bearings are 'sealed,' resin remover can sneak in and dissolve the bearing grease. If this were to happen, you would be faced with the problem of trying to lubricate a sealed bearing.
Despite the claims of bearing grease sellers, we've never had much luck with this. Once that grease is gone, just go buy a new bearing.
Periodically inspect the shanks of your router bits for rust or burrs. Either of these can be removed quickly with ScotchBrite®. Left on, they can interfere with your ability to properly tighten the bit in the collet.
