Dremel 636 metric brad-point set
636 is a metric brad-point family with 3, 4, 5 and 6 mm working sizes.
How to choose
Compare the exact metric hole you need with the four supplied sizes. The larger cutting diameters do not establish the size of the holder, so confirm tool-side fit separately.
Compatibility and limits
Metric brad points in 3, 4, 5 and 6 mm working diameters
Care
Before mounting the accessory, check its speed rating against the tool and use the holder specified for its shank or mandrel. Refer to the exact model instructions for the workpiece.
Questions before buying
Can I substitute a similarly sized bit from the 631 inch set?
Match the actual hole size. The 636 gives exact metric working sizes, while the 631’s four cutting sizes are specified in fractions of an inch.
