Description
Thumbnail Router Bit.
The PRO-TECH Thumb Nail Router Bit 2 1/2″ X 3/4″ 1/2″ KP357411 gives your furniture and cabinets a classic, architectural look. Perfect for chair rails, crown moulding, door casings, trim, pilasters, window casing/sills, baseboards, and picture frames, you can use the full profile or just a portion of it to achieve the look you want.
The timber is held securely against the fence, and the bit makes the cut. This leaves you free to feed the timber steadily, and your hands can safely be a long way from the cutters. Plan to cut the profile in several passes, taking only a small amount off on the last cut to get the best quality. It features two flutes and a 1/2” ball bearing guide.
This two-flute router bit is well-balanced, eliminating vibration that degrades the cut finish.
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.
Bit Shanks:
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.
