    Straight Mortising Bit Double Flute, 1/4" Dia. 1/4" Shank, 5/8" Cutting Height, 2" Length

    Description

    Straight Mortising Bit Double Flute 1/4 Dia Use

    Straight Mortising Bit Double Flute 1/4 Dia is a Freud Tool router bit designed for general stock removal with a smooth finish, so it handles cleanup and sizing passes where a consistent surface matters. The 1/4 inch diameter cutting profile shapes narrow grooves and mortises, which is useful when laying out joinery or relief cuts in tight areas. A 1/4 inch shank matches routers that accept this common shank size, so the bit fits typical professional and serious DIY setups using that collet size. The 5/8 inch cutting height gives enough depth for many shallow mortises and dados without overextending the tool, helping maintain control during passes. With an overall 2 inch length, the bit stays compact in the collet, which supports stable cuts on routers used in cabinetry and woodworking shops.

    Key Details That Support Clean Routing Work

    • The double flute straight mortising design shapes material with two cutting edges, which distributes the cut across the bit and supports smoother stock removal on appropriate passes.
    • The 1/4 inch diameter focuses cutting in a narrow path, which is useful when routing slim slots, mortises, or reliefs where wider bits would remove too much material.
    • The 5/8 inch cutting height defines how deep you can plunge in one pass, which helps plan mortises and dados that stay within that depth range during layout.
    • The 2 inch overall length keeps the bit relatively short in the collet, which supports better control and reduced leverage on the router during straight plunges and tracking cuts.
    • The 1/4 inch shank is compatible with routers that accept that shank size, which aligns the bit with many hand-held and table-mounted portable routers using a 1/4 inch collet.
    • The Freud Tool brand and 04-105 part number identify the bit within the Straight Mortising Router Bits class, which helps match this specific cutter when standardizing tools or reordering.

    Routing Setup And Machine Use Considerations

    This Freud Tool straight mortising bit is specified for use on CNC and other automatic routers, which means it is suited to repeatable motion paths where the machine controls feed and direction. It is also specified for hand-held and table-mounted portable routers, so the same cutter can move between shop jigs and freehand work where a router table or hand routing is preferred. The bit cuts all composition materials, plywoods, hardwoods, and softwoods, so a single cutter can handle a range of sheet goods and solid stock within that material group during typical cabinet and woodworking jobs.

    Using This Freud Mortising Bit In Woodworking

    Where This Straight Mortising Bit Fits Best

    This Straight Mortising Bit Double Flute 1/4 Dia sits in the Straight Mortising Router Bits class, so it is oriented toward creating straight-walled cuts such as grooves and mortises. The ability to cut all composition materials, plywoods, hardwoods, and softwoods means it works across common cabinet carcass panels and solid frames made from those materials. Being specified for CNC and other automatic routers positions it for production settings where the bit will track programmed toolpaths in nested-based or dedicated routing operations. Its suitability for hand-held and table-mounted portable routers connects it to on-site or small-shop workflows where the same bit moves between edge guides, templates, and router tables handling straight channel cuts. The 1/4 inch diameter is well sized for narrow slots and mortises, so it can form lighter joinery or clearance grooves without removing excessive material in one path.

    Why These Bit Details Support Consistent Results

    The general stock removal with a smooth finish application means the bit is configured to remove material while leaving a surface that reduces follow-up smoothing steps on qualifying cuts. The double flute layout provides two straight cutting edges, which engages the material more often per revolution and supports smoother straight walls when the router follows a stable guide. The 5/8 inch cutting height sets a defined working depth, which helps keep cuts within a manageable range for joints and grooves that do not require deep plunges. The 2 inch overall length positions the cutting edges near the collet on compatible routers, which can support reduced deflection during straight plunging and slotting work. With a 1/4 inch shank matched to routers accepting that size, the bit integrates into common portable routers used by professionals and serious DIY users following their established routing setups.

    How deep can this double flute mortising bit cut in one pass?
