Overview
Festool 491066 Dowel Drill Router Bit, HW 5X30mm
The Festool 491066 Dowel Drill Router Bit, HW 5X30mm is a router bit made for drilling clean, repeatable dowel holes and hole series in wood. This is a dowel drill router bit designed for accurate dowel drilling and line-boring style hole work with compatible Festool routers. Model Number 491066. If you are building cabinets, furniture, or any project where hole placement needs to stay consistent, this bit is built for that kind of work.
What makes this bit different from a standard drill bit is its geometry. Festool designed it specifically for high cutting speeds when routing, which is a big deal because a router runs very differently than a drill. The brad point helps the cutter start where you want it, and that extra guidance is useful when you are spacing out a row of holes or drilling for dowels where alignment matters.
The cutting size is 5 mm, or 7/32 inch, with a 30 mm flute length and 53.5 mm overall length. That gives you a compact, purpose-built bit for precise woodworking tasks without extra bulk. The 8 mm shank is matched to the Festool router setup this accessory is intended for, so you are buying a dedicated solution instead of trying to adapt a general-purpose bit.
In practical use, this bit makes the most sense for shops and installers already working in the Festool router platform. It is suitable for the OF 900, OF 1000, OF 1010, OF 1010 R, and OF 1400. Paired with a hole drilling system, it helps speed up repeat hole layouts while keeping the cut quality controlled.
This is the right accessory for cabinetmakers, furniture builders, finish carpenters, and serious DIY users who want cleaner starts and better consistency when routing dowel holes. If your work includes shelf-pin style hole runs, dowel joinery, or repeat drilling in wood components, this bit is a more purpose-driven choice than a standard twist bit used in the wrong tool.
Better Starts for Accurate Hole Placement
When you are drilling for dowels or a row of matching holes, the biggest problem is drift at the start. The brad point on this bit helps it track into position cleanly so the hole starts where you intended.
- Brad point design improves guidance at the start of the cut
- 5 mm diameter is suited to precise dowel and hole-series work in wood
Made for Router Speed, Not Drill Guesswork
This accessory is built specifically for routing conditions. That matters because a router bit meant for high speed operation gives you a more controlled result than using a standard bit in an application it was never designed for.
- Optimized for high cutting speeds when routing
- 8 mm shank fits select Festool router models
Useful Dimensions for Repeat Woodworking Tasks
The size of this bit lines up with the kind of detailed work where consistency matters more than brute force. It is a straightforward accessory for clean, repeated drilling in wood parts and panels.
- 30 mm flute length gives working reach for common dowel-hole tasks
- 53.5 mm overall length keeps the accessory compact and purpose-built

Pro Tip
If you are drilling a row of dowel or system holes, set your router depth once and let the brad point do the locating work at each stop. That keeps the start of every hole cleaner and more consistent, especially on finished stock.
