Bosch 11317EVS Demo hammer

[Rilles]

Can someone help me? I joined this forum just to ask this question. What the heck bit fits a Bosch 11317EVS demo hammer? I got this machine cheap, and I think I know why, I cannot find any bits that fit, I've bought, and returned three that I thought should fit. Can anyone here give me a clue as to what bit I'm looking for? Or maybe a part is missing? Thanks in advance!

Measure the opening on the tool.
Looks like 30mm hex bits for demolition jack hammers.

Measure it first, but this might help you: Bosch 3/4 hex hammer steel

Ah, I think you're right. I checked the Bosch bits available on the WS, I guess I missed these. Thanks so much.

This page says 3/4" hex, so GRayflatop should have it nailed.

You can find a manual here, and it confirms 3/4" hex too

@Rilles
Late to the party. This is a chipping hammer only. No rotation. 3/4 hex used to be fairly common in these size rotary hammers. Some spline hammers accepted 3/4 hex but those had a round end shaft where the splines would normally be instead of full shank hex. Both should have a keyway slot for retention.
