DOUBLE FLUTE STRAIGHT BIT identifies this Freud Tool router bit as a straight mortising double flute design for routing grooves and pockets. The straight mortising profile handles tasks where a flat-bottom cut is needed, which helps when forming mortises or dados in cabinet and furniture components. The bit has a 5/16 inch diameter that defines the cut width in a single pass, which supports accurate layout when matching mortise widths to tenons or hardware clearances. A 1/4 inch shank fits routers that accept this standard shank size, so it can be used on many common shop and jobsite routers that are built around 1/4 inch tooling. The overall 2 inch length provides reach for typical stock thicknesses while keeping the bit compact, which matters when routing in portable routers or table setups that benefit from reduced projection.
The 1/4 inch shank on this Freud Tool router bit determines which routers it fits, so it seats into collets sized for 1/4 inch tooling in handheld and table-mounted machines. The 5/16 inch cutting diameter sets the width of every pass, which simplifies fence and guide settings when laying out mortises or dados that must align with mating parts. The total 2 inch length defines how far the bit extends from the collet, which influences maximum cut depth and clearance above the work when routing in jigs or on CNC fixtures. The straight double flute geometry classifies the bit as a straight cutter rather than a profiling tool, which suits tasks centered around interior stock removal instead of edge shaping.
This Straight Mortising router bit belongs to the Router Bits product class, so it is intended for routing rather than drilling or sawing operations. Its application for general stock removal with a smooth finish means it is suited to operations where material must be cleared inside a layout line while still leaving a clean surface, such as mortises, dados, and slots in cabinet parts or fixtures. The ability to cut composition materials supports use in engineered panels, so operations on many sheet goods can be handled with the same profile. Capability in plywoods directly addresses common cabinet carcass work where dados and grooves are needed in multi-ply material. Suitability for hardwoods allows this same bit to handle solid wood furniture parts, so mortises in legs or rails can follow the same cutter setup. The rating for softwoods extends its use to framing or shop-built fixtures, keeping the same cut profile available on more forgiving materials.
The 5/16 inch diameter fixes the cut width, which simplifies designing joinery where tenons or hardware must match a dependable mortise size. The straight double flute construction presents two cutting edges, which balances the cut and helps maintain a straight-walled cavity for joinery fit. The 1/4 inch shank interface defines the gripping area in the router collet, which supports secure holding when tightened according to the router design. The 2 inch overall length governs projection beyond the collet, which affects how deeply mortises or slots can be routed while maintaining a compact stack height above the work. Identification by manufacturer part number 04-118 ties all these characteristics to a single cataloged Freud Tool bit, which supports repeating a known configuration whenever the same mortising or groove profile is required on future jobs.
This Freud Tool bit is specified for CNC and other automatic routers as well as hand-held and table-mounted portable routers, so it functions across common routing platforms in shop and field environments.
The 5/16 inch diameter sets the exact width of the cut, so layouts and mating parts can be sized to that dimension for predictable joint and hardware clearance results.
This router bit cuts composition materials, plywoods, hardwoods, and softwoods, so one cutter can be applied to engineered sheet goods and solid lumber in many cabinet and furniture projects.
The 1/4 inch shank size determines collet compatibility, so it fits routers designed to hold 1/4 inch bits, providing a defined gripping surface for secure mounting.
The double flute straight design provides two straight cutting edges that share the load, promoting smoother chip removal and straight-walled cavities useful in mortises and grooves.
The 2 inch length describes the bit's overall size, which defines available projection from the collet and influences how deep mortises or slots can be cut within common stock thicknesses.
This Freud Tool Straight Mortising router bit with 5/16 inch diameter, 1/4 inch shank, and 2 inch length is aimed at general stock removal with a smooth finish in composition materials, plywoods, hardwoods, and softwoods. Its compatibility with CNC, automatic, hand-held, and table-mounted portable routers ties one part number 04-118 to many routing setups. For mortises, grooves, and dados that benefit from straight walls and flat bottoms across varied wood-based materials, this DOUBLE FLUTE STRAIGHT BIT offers a clearly defined cutting profile ready for repeated cabinet and woodworking tasks.
