Brand new, never used 3/8" key hole hanger router bit with 2 carbide cutting flutes and a 1/2" shank. Serves for plunge cutting a 3/8" hole to a desired depth at which point the router is slid laterally allowing the bit to cut a 1/4" slot along the top surface while maintaining a 3/8" cleared channel below. Thus a key hole slot is created that can be used to hang all manner of things by passing a fastener head through the large hole and sliding the screw or nail laterally such that the shank passes along the narrow channel trapping the head in the wider one behind. We have all seen this hanging mechanism in one or another form. Extending this pattern in a linear fashion along a ripping creates a long channel which, when the ripping is then turned 90 degrees and hung on a wall, will accept brackets and hangers. This is often referred to as a T-slot hanger. You can use them to make custom shelves and hangers for the back wall of your work bench or hanging and organizing clutter in the garage This bit will fit 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.
