can you sell me this bit with a "spline " shank?

Asked by: mick
Thank you for your question. The Bosch HC8526 has an SDS-Max shank so it will not work directly with a Spline hammer, however we do make an adapter that will allow use of this bit with a Spline hammer, the SDS-Max to Spline adapter part number is HA1031. We also make a Spline core bit in the same size as the HC8526 that you can use with a Spline hammer and would not require an adapter, the part number is HC8026.

Does this make a hole big enough for a 4" dryer duct? I'm looking for an answer from someone other than Bosch, as I've called and chatted online with them, and they are only able to tell me it makes a 4" hole. It seems that 4" bits are much more common than 4 1/8" bits, so I would think so -- just want to confirm before making a significant purchase.
Asked by: Bruce
Thank you for your question. The HC8555 will provide a 4" outer diameter hole. A 4" dryer duct would fit snug with some work.
