Infinity Tools 1/2" Shank 4-Pc. Extra Long Straight Router Bit Set

The set includes 3/8", 7/16", 1/2", and 3/4" cutting diameters, covering the most-used straight-bit sizes. See more straight router bits.

All four bits have 1/2" shanks, so your router must accept a 1/2" collet. The larger shank runs smoother and resists deflection in deep cuts.

They offer carbide heights of 1-1/4" to 1-1/2" and overall lengths up to 3-1/4", giving extra reach for deep dadoes, thick stock, and template work.

Yes. The set includes a PBK-104 bearing kit (1/2" I.D. x 3/4" O.D. bearing with stop collar) so you can set up a bit for pattern routing against router templates.

Use them for dadoes, rabbets, grooves, mortises, and pattern cuts — essentially any operation needing a clean, straight edge. Pair them with other grooving bits.

The product information recommends choosing models with down-shear cutting action for an ultra-smooth finish. Down-shear bits slice fibers downward to reduce tear-out.

Yes. Each is a carbide-tipped straight bit listed with its carbide cutting height and built for many sharpenings of service.

The 12-611 and 12-690 both have a 3-1/4" overall length, the longest in the set, with the 12-690 offering the widest 3/4" diameter.
