Tool combination having a chisel holder and two chisels

18:

• The tool combination of claim 17, wherein:
• the trailing chisel tip is formed, at least in some areas, of a superhard material.

21:

• The tool combination of claim 18, wherein:
• the trailing chisel tip includes a base support formed of a carbide material, the base support facing toward the trailing cutting edge being covered by the superhard material.

22:

• The tool combination of claim 18, wherein:
• the superhard material is configured as a layer.

23:

• The tool combination of claim 17, wherein:
• the trailing chisel is connected to the chisel holder such that the trailing chisel is fixed axially and is fixed in a peripheral direction of the trailing chisel.

24:

• The tool combination of claim 23, wherein:
• the leading chisel is connected to the chisel holder such that the leading chisel is held axially and is rotatable in a peripheral direction of the leading chisel.

25:

• The tool combination of claim 17, wherein:
• the leading chisel is connected to the chisel holder such that the leading chisel is held axially and is rotatable in a peripheral direction of the leading chisel.

26:

• The tool combination of claim 17, wherein:
• the trailing chisel is connected to the chisel holder in a non-exchangeable manner.

27:

• The tool combination of claim 26, wherein:
• the leading chisel is exchangeably connected to the chisel holder.

28:

• The tool combination of claim 17, wherein:
• the leading chisel is exchangeably connected to the chisel holder.

29:

• The tool combination of claim 17, wherein:
• the trailing chisel tip is soldered to the chisel holder so that the trailing chisel tip is directly and non-detachably connected to the chisel holder.

32:

• The tool combination of claim 17, wherein:
• the trailing chisel is configured and arranged to rework a milling performed by the leading chisel.

33:

• The tool combination of claim 17, wherein:
• the trailing chisel is configured and arranged to cut a smaller chip volume than is the leading chisel.

34:

• The tool combination of claim 17, wherein:
• the leading chisel and the trailing chisel are configured and arranged on the chisel holder such that when the tool combination is mounted on the milling drum the leading cutting edge of the leading chisel tip is arranged on a larger radius from a rotational axis of the milling drum than is the trailing cutting edge of the trailing chisel tip.

35:

• The tool combination of claim 17, wherein:
• the leading chisel and the trailing chisel are configured and arranged on the chisel holder such that when the tool combination is mounted on the milling drum the leading cutting edge of the leading chisel tip and the trailing cutting edge of the trailing chisel tip are arranged on radii equal to within ±3 mm from a rotational axis of the milling drum.

38:

• The tool combination of claim 37, wherein:
• the distance between the leading cutting edge and the trailing cutting edge is in a range of from 50 mm to 60 mm.

39:

• The tool combination of claim 37, wherein:
• the smaller radius is from 2 mm to 5 mm smaller than the larger radius.

40:

• The tool combination of claim 17, wherein:
• the leading chisel and the trailing chisel are configured and arranged on the chisel holder such that when the tool combination is mounted on a milling drum a setting angle of the trailing chisel relative to a radial line running from a rotational axis of the milling drum through the trailing cutting edge is smaller than a setting angle of the leading chisel relative to a radial line running through the leading cutting edge.

42:

• The tool combination of claim 17, wherein:
• the chisel holder includes a joining zone where the trailing chisel is joined to the chisel holder, and the joining zone is at least partially covered by the leading chisel in a direction of the working movement of the tool combination from the trailing chisel.

43:

• The tool combination of claim 17, wherein:
• the leading chisel protrudes beyond the trailing chisel transversely to the working movement of the tool combination.
