The Festool 491064 Dowel Drill Router Bit, HW 5x30mm is a carbide-tipped dowel drill bit for use in compatible Festool routers. This is a dowel drill router bit designed for drilling clean, consistent dowel holes in woodworking applications. Model Number 491064. If you're building cabinets, assembling furniture, or doing precise panel joinery, this bit gives you the diameter and drilling depth needed for accurate dowel placement.

The core numbers here matter because they directly affect fit and hole quality. The 5 mm cutting diameter is sized for 5 mm dowel work, while the 30 mm drilling length gives enough reach for common joinery tasks without getting overly flexible. Festool lists an overall length of 53.5 mm, which keeps the bit compact enough for controlled routing while still providing practical cutting depth.

This bit uses HW cutting edges, meaning carbide-tipped construction. On the job, that matters because carbide holds an edge longer than basic high-speed steel when you're drilling repeated holes in wood-based materials. If you're doing a run of shelf supports, cabinet side panels, or dowel alignment holes, longer edge life means fewer interruptions and more consistent results across the whole batch.

The 8 mm shank is the other important detail. It is built to fit specific Festool routers rather than being a universal bit for every router on the shelf. That makes this a better choice for users already working inside the Festool routing system, especially if they want a bit that matches the router collet and intended application without adapter workarounds.

Festool identifies this accessory as suitable for the OF 900, OF 1000, OF 1010, OF 1010 R, OF 1400, OF 2000, and OF 2200 routers. That compatibility gives it a broad range across smaller trim-capable routers and larger full-size models. If your workflow includes cabinet installation, shop-built fixtures, furniture construction, or repeat drilling in wood panels, that kind of cross-platform fit is useful because the same bit can move with your router lineup.

Who should buy it? Woodworkers, cabinetmakers, remodelers, and serious DIY users who need precise dowel holes and already own a compatible Festool router. If you are just looking for a general-purpose straight bit, this is more specialized than you need. But if dowel joinery is part of the job, the Festool 491064 Dowel Drill Router Bit, HW 5x30mm is the right kind of purpose-built accessory: correct size, router-specific fit, and made for repeatable hole drilling instead of all-around cutting.

Specialized, simple, and exactly what dowel work calls for

The Festool 491064 Dowel Drill Router Bit, HW 5x30mm is the kind of accessory that makes sense the minute precision dowel joinery becomes part of your routine.

• Who it's for: Woodworkers, cabinet installers, and furniture builders using compatible Festool routers for repeatable dowel hole drilling.
• Why it stands out: You get a purpose-built 5 mm dowel drill bit with carbide-tipped cutting edges, a useful 30 mm drilling length, and fitment across a wide range of Festool routers.
• Worth knowing: This is a specialized router bit, not a general straight bit. Make sure your router accepts an 8 mm shank before you order.
