It's that easy…

Closure of cooling ducts

1. First, mill a recess around the cooling duct (2-4mm larger than the diameter of the cooling duct and at least 3mm deep).

2. The concave plug is pressed down into the recess with locktite.

3. The concave stopper is fixed with a mandrel and hammer. When the concave surface is pressed down, the concave plug expands, thus closing the channel completely.

Connection of cooling ducts

1. Between the cooling ducts to be connected, first cut a depression with the same diameter as the ducts and an additional depth of 3 mm.

2. Close the recess on the extra 3 mm, as described in steps 2-3 under "closing the ducts"
