The Freud 11-180 1/2-Inch Single Flute Straight Router Bit is a solid carbide straight router bit built for fast cutting and efficient waste removal in wood and composite materials. This is a straight router bit designed for high-feed dado, groove, and straight cutting work. Model Number: 11-180. If you are running production passes where chip buildup can slow you down or heat up the cut, this bit is built to move material out of the way and keep the cut moving.

The big selling point here is the single flute geometry. On the job, that means more room for chips to evacuate during the cut, which helps when you are pushing feed rates in plywood, hardwood, softwood, MDF, OSB, particle board, and other composites. Freud calls this out as a high-production bit for maximum chip clearance, and that matters because cleaner evacuation usually means less burning, less recutting of debris, and a more predictable cut when you are machining slots or straight profiles.

This bit uses a 1/2 inch cutting diameter and a 1/2 inch shank, which puts it in the heavier-duty class for routers that can take a full-size shank. The larger shank helps with rigidity compared to smaller shank bits, especially when you are taking longer passes or working with a tall cutting length. Freud lists a 2-1/2 inch carbide height and a 4-3/8 inch overall length, so this is not a stubby trim bit. It is sized for deeper reach and taller edge or groove work where more cutting length is useful.

Freud also notes end-of-bit relief for plunge cutting, which gives this bit added flexibility beyond simple edge entry. If your setup calls for dropping into the workpiece before moving into a straight pass, that feature makes the bit more useful than a basic straight cutter. For CNC routing, that can help when toolpaths start inside the panel. For table or hand-held router work, it broadens the kind of joinery and slotting tasks the bit can handle.

Material fit is broad, and that is a practical advantage. This router bit for wood and composite cutting is intended for hardwood, softwood, plywood, and composite sheet goods, so it makes sense in cabinet work, fixture building, sign work, and general shop production. If you regularly move between plywood parts, solid stock, and engineered panels, you do not have to treat this as a single-material specialty bit.

Freud rates the bit for up to 24,000 RPM. That gives you a clear ceiling when matching the bit to your router or CNC spindle setup. Staying inside that operating range matters for cut quality and bit life, especially on long runs or when cutting sheet goods that generate a lot of chips. In plain terms, this bit is meant to work fast, but it still needs to be run within the correct speed window.

Who should buy it? This bit makes the most sense for woodworkers, cabinet shops, CNC users, and serious DIY users who need a straight cutting bit that prioritizes chip evacuation and production efficiency. If you mostly do light trim work, a shorter bit may be all you need. If you cut deeper grooves, machine parts from sheet stock, or want a single flute router bit that can stay productive in a range of materials, this one is the smarter fit.

Freud 11-180 1/2-Inch Single Flute Straight Router Bit for Shops That Need to Keep Moving

This is a smart pick if your priority is straight cuts with better chip clearance and faster production in wood and sheet goods.

• Who it's for: Woodworkers, cabinet shops, CNC users, and serious router owners cutting grooves, slots, and straight profiles in wood or composites.
• Why it stands out: The single flute design, long 2-1/2 inch carbide section, and 1/2 inch shank make it better suited for productive cutting than a basic short straight bit.
• Worth knowing: This is a 1/2 inch shank bit, so make sure your router or collet is set up for that size before you order.

• What type of tool is this? It is a single flute straight router bit designed for straight cutting, grooves, slots, and production routing in wood and composite materials.
• Will it fit any router? No. It has a 1/2 inch shank, so your router or router table setup must accept 1/2 inch shank bits.
• Can it be used in a CNC router? Yes. Freud lists it for CNC, hand-held, and table-mounted router use.
• What is the maximum rated speed? The maximum rated speed is 24,000 RPM.
• What materials is it made to cut? Freud lists hardwood, softwood, plywood, and composites, including common sheet goods such as MDF, OSB, and particle board.
