what kind of chisel bit does it use,
Thank you for your question.

can SDS bits be used in this drill
No, this hammer will only accept hex and spline bits.
Just hex and spline bits on this model
Thank you for your question. The RH540S Rotary Hammer is a Spline hammer that is compatible with spline bits only. For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from Mon-Fri 7A-7P CST.
How many amps is this drill? And does it take spline and sds max bits?
Thank you for your question. The RH540S has a 12 amp motor and accepts Spline bits. We also offer the RH540M which is the same rotary hammer as the RH540S however it accepts SDS-Max bits.
There is a mark on the drill head that you line the bit up with pull down on the head and set the bit after release the head
The rotary hammer is 12 amps.
I am unable to compare for some reason on the website. I am wondering what is the difference between the RH540M and the RH540S
The RH540S has vario-lock positioning rotates and locks chisel into 12 different positions to optimize working angle and the RH540M has a 20 plus 1 clutch settings perfect torque adjustments for precise screw driving.
Thank you for your question. The only difference is the bit/accessory holder. The RH540M accepts SDS-Max shank accessories and the RH540S accepts Spline shank accessories. Otherwise both tools are identical as far as features, power and specifications.
The only difference is the bit it takes. The RH540S takes a spline bit and M takes sds bits as far as I can figure
