1. A tool bit assembly comprising:

a shank comprising an elongated shaft, an intermediate portion extending from the elongated shaft, a head extending from the intermediate portion, and a tool portion extending from the head;

a retainer comprising a first end and a second end with a body defining a hollow shaft therebetween, the hollow shaft configured to receive at least a portion of the elongated shaft of the shank therethrough; and

a washer having a first end and a second end, the washer defining an opening extending from the first end to the second end of the washer, the washer comprising at least a first step and a second step, the opening of the washer configured to receive at least a portion of the intermediate portion of the shank therethrough,

wherein the first step is configured to abut a bottom surface of the head of the shank, and the second step is configured to abut a first shoulder of the intermediate portion of the shank.

2. The tool bit assembly of claim 1 , wherein the tool portion of the shank comprises a carbide tip.

3. The tool bit assembly of claim 1 ,

wherein the opening of the washer defines a first passage extending from the first end to the second step and a second passage extending from the second step to the second end, and

wherein the first passage and the second passage are configured to receive at least a portion of the intermediate portion therein, and

wherein the second end abuts the first end of the retainer.

4. The tool bit assembly of claim 3 , wherein a top surface of the head of the shank has a first diameter and the bottom surface of the head of the shank has a second diameter larger than the first diameter.

5. The tool bit assembly of claim 4 , wherein the intermediate portion comprises a first engagement surface comprising the first shoulder, the first engagement surface having a third diameter smaller than the second diameter.

6. The tool bit assembly of claim 5 , wherein the first passage receives at least a portion of the first engagement surface therein.

7. The tool bit assembly of claim 3 , wherein a transition between the first step of the washer and the first passage comprises a first radiused portion.
