Freud solid carbide up spiral bit is a straight mortising router bit designed for through-cuts, mortises and deep blind holes in production applications, so it handles common joinery and cutout tasks with consistent cut quality. The 1/4 inch diameter pairs with a 1/4 inch shank, giving a straightforward match to routers designed for that shank size while keeping the cut width tight for detail work. The overall 2 inch length supports mortises and blind holes of practical depth within that range. The up spiral design moves chips up and out of the cut, which keeps the cutting edges working efficiently instead of recutting waste. That same up spiral pattern delivers the best cut quality on the bottom surface of the material, which helps when the visible face is on the bottom side of a through-cut or groove. Being part of the Freud Premier Solid Carbide line means the cutting portion is solid carbide, which supports long life and stable performance in demanding production environments where bits see repeated passes and extended run times.
This up spiral router bit uses a 1/4 inch shank, so it fits collets sized for that shank in CNC, hand-held or table-mounted routers, keeping setup straightforward across machines. The 1/4 inch cutting diameter means the cut path matches that dimension, which helps when sizing mortises or through-slots to a specific width in layout and programming. With a total length of 2 inches, the usable cutting depth aligns with mortises, through-cuts and deep blind holes that fall within that bit reach, helping plan cut depth and pass strategy around a known tool length. Because the bit belongs to the straight mortising class, it suits plunge-style entry where mortises or deep blind holes start inside the material surface rather than only from an edge.
This Freud up spiral router bit is designed for through-cuts, mortises and deep blind holes in production applications, so it fits repetitive cabinet, furniture and component work where the same profiles are routed many times. The straight mortising classification matches tasks like cutting slot mortises and pockets that begin with a plunge, giving flexibility for internal joints and hardware clearances. The up spiral design focuses on delivering the best cut quality on the bottom surface of the material, which is especially useful when the show face is oriented down on the router table or CNC bed. Fast chip removal from the up spiral geometry keeps the flutes clearing waste, which supports smoother cutting when passes are repeated across multiple parts in a run. Because the bit can be used in CNC routers, it fits automated nested-based cutting or dedicated mortising programs as part of a production workflow.
The solid carbide construction, described as providing fast chip removal with excellent quality and long life, means the cutting edges hold up over extended service, so cut dimensions and surface finish stay consistent across batches. The 1/4 inch shank and 1/4 inch diameter give a predictable tool profile, making it straightforward to dial in mortise widths, slot paths and clearances in jigs or CNC toolpaths without changing to different diameters. The 2 inch length defines how deep mortises and deep blind holes can go, helping set conservative depth limits while keeping enough reach for common joinery depths. In CNC, hand-held and table-mounted routers, using the same up spiral bit means the bottom surface cut quality remains similar across different setups, which reduces variation when parts are routed on multiple stations. Overall, the combination of straight mortising design, solid carbide construction and up spiral geometry supports accurate, repeatable cuts that align with production-style routing.
The Freud up spiral bit is designed for through-cuts, mortises and deep blind holes, so it covers typical straight mortising, slotting and pocketing work in woodworking and similar routing tasks.
The up spiral design provides the best cut quality on the bottom surface of the material, which helps when the visible or reference face is on the underside during routing.
The 1/4 inch shank fits routers with 1/4 inch collets, and the 1/4 inch diameter sets the actual cut width, which is important for sizing mortises and slots.
This up spiral bit is specified for use in CNC routers, hand-held routers and table-mounted routers, so it fits automated and manual routing setups.
The solid carbide construction is described as providing fast chip removal with excellent quality and long life, which supports extended use and consistent cutting performance.
The bit has a 2 inch length, so practical routing depth for through-cuts, mortises and deep blind holes is planned within that reach.
The Freud solid carbide up spiral bit with 1/4 inch shank, 1/4 inch diameter and 2 inch length offers a defined tool profile for through-cuts, mortises and deep blind holes in production applications. Its up spiral design focuses chip removal and bottom surface quality, which supports cleaner results when the finished face is down on the table or CNC bed. With suitability for CNC, hand-held and table-mounted routers, this straight mortising bit can serve across multiple routing stations. For shops needing a dedicated tool for repeat mortising and slotting, this Freud up spiral router bit aligns well with that role.
