Product Information
Full details
This Bosch Professional Arbour-mounted Countersink (3 mm) is designed for woodworkers and DIY enthusiasts needing to efficiently drill, countersink, and deburr holes in a single operation. Its key benefit is the significant time savings and consistent results achieved by combining three tasks into one pass. A potential caveat is that it requires a separate brad point drill bit for operation. It features a durable tool steel construction, five cutting edges, and a 90-degree countersink angle, making it suitable for a variety of wood materials.

FAQs
What is the main advantage of this arbour-mounted countersink?
The primary advantage is its ability to drill, countersink, and deburr in a single step, saving time and ensuring consistent results when working with wood.
Do I need a special drill to use this countersink?
No, it is designed for use with standard drill stands and drill drivers. However, it requires a separate brad point drill bit to function.
What materials can this countersink be used on?
It is suitable for hard and soft wood, laminated and non-laminated chipboard, and plywood.
Does this product include the brad point drill bit?
No, the brad point drill bit is not included with the arbour-mounted countersink.
What is the countersink angle?
The countersink angle is 90 degrees.
Can this tool be used as a depth stop?
Yes, the design allows it to be used as a depth stop for controlling hole depth.
How do I maintain the countersink bit?
Clean off wood debris after use and store in a dry environment to prevent rust. Ensure the set screw remains tight.
Troubleshooting
Countersink not cutting cleanly
Ensure the drill bit is sharp and the countersink has five sharp cutting edges. Check that the material being drilled is properly supported and that the drill speed is appropriate for wood. Make sure the countersink is securely mounted.
Countersink wobbles during use
Verify that the countersink is securely tightened onto the brad point drill bit using the hexagon pin key. Ensure the brad point drill bit itself is securely clamped in the drill chuck.
Drill bit breaks during operation
The countersink is designed to be used with appropriate drilling techniques. Avoid excessive force and ensure the drill bit is suitable for the material. The countersink itself is not the cause of drill bit breakage unless improperly mounted or used.
Tool won't fit on drill bit
Confirm you are using a compatible brad point drill bit. The arbour-mounted countersink is designed for specific drill bit shank dimensions. Ensure there are no obstructions on the drill bit shank where the countersink needs to mount.
