This is the striking tool in an EDCO grinder tooling change. It is used with the punch, not on its own and never directly on the accessory: the hammer drives the punch, the punch drives the wooden wedge, and the wedge is what holds a Dyma-Sert or a Strip-Sert in position on the multi-accessory disc. Get that order wrong and the repair bill is the tooling, not the hammer.

- Removing tooling that has seized after a long grind

How it is used, and the one mistake to avoid
The procedure EDCO publishes is simple. Use the hammer and punch together to make sure the wooden wedges keep the Dyma-Serts or Strip-Serts in place on the multi-accessory disc. Grinding stones can also be installed using the hammer with a wooden wedge. The hammer will also break tooling loose for removal. The warning that matters is this: never hammer directly on any accessory. A direct blow damages the self-adjusting system, and once that is damaged the accessory has to be replaced. On a disc full of Dyma-Serts that is an expensive lesson, and it is the reason the hammer and punch are sold and stored as a pair.

Frequently asked questions
Can I just use my own hammer?
Most contractors buy the EDCO hammer so it lives in the tooling box with the punch and is actually there when a disc needs changing. The critical point is not the brand of hammer, it is that the blow goes onto the punch and never onto the accessory.
Why can I not strike the Dyma-Sert directly?
Because it damages the self-adjusting system, and once that is damaged the accessory has to be replaced. The wedge and punch exist so the force is applied where the tooling can take it.
Does this come with the punch?
No, the 12003 is the hammer only. EDCO's 12004 black tool box is supplied with both a hammer and a punch if you need the pair.
What are the wooden wedges for?
They lock the Dyma-Serts or Strip-Serts into position on the multi-accessory disc. The punch drives the wedge home and the hammer drives the punch.
Can it be used to install grinding stones?
Yes. EDCO notes that grinding stones can also be installed using the hammer together with a wooden wedge.
