This is a brand new, never used 5/8" cutting diameter straight router bit with two carbide flutes (blades) and a special gullet between cutting edges that allows for material clearing in mortising applications. The geometry of the blades and the open space between them is designed to allow for clean edge and clear bottom mortising up to about 3/8" depth for shallow hinges. The bit will plunge up to the full blade length, but will cease to have any special clearing properties once the hinge mortising portion is buried. It may also be used as a general purpose straight bit to clear dado channels for woodworking joinery, or, in conjunction with a router plate guide bushing or an added shank bearing, for flush cutting to a template. This bit fits all 1/2" shank portable and table routers. C2 Micrograin tungsten carbide cutting edge provides a good balance of strength and durability. Harder C3 and C4 carbides wear somewhat more slowly, but are also more brittle, meaning they are more likely to chip in an encounter with an unseen nail or embedded rock. Softer C1 carbides wear more quickly, but are likewise the most resistant to shock damage. All Carbide wear at a rate at least 10x slower than their high speed steel equivalents.

These router bits are no exception! They are the only 1/2" shank bits i use, and they stand up to the highest priced name brand equivalents with absolutely no downside. Opposite the case of circular and chainsaw blades with flat tips intended only to cut a line, many router bits have detailed cutting edges with critical clearance sizes that cut perfectly only when the edge is virgin. Additionally, most of us don't have the capacity to machine sharpen curved edges common to all but straight bits, so the carbide tip ends up being wasted when we toss old bits to buy new ones. These bits last as long as any others I have ever used. If intended for occasional use, they should pretty much last forever, and again, if you beat your bits and dull them frequently, I dare anyone to find a way to restore the carbide edge for less than the cost of a shiny new one of these... Use them like disposable HSS bits, but enjoy the 10x longer life! Best offer feature is primarily intended for customers to suggest combined shipping discounts.
