BEST DD550 – Frequently Asked Questions
1) What is a combinating hammer used for on BEST interchangeable core locks?
The BEST DD550 is a plastic-head hammer used during combinating work, which is the bench process of building and re-pinning cores to a keying schedule. The plastic head is the point of it: it drives caps and seats components without marring the soft brass and nickel-silver parts a steel hammer would deform. It is part of the BEST DD Series service equipment line, so it is meant to sit alongside the rest of that bench kit rather than be used as a general shop hammer.
2) Will a plastic-head hammer damage BEST core pins or caps?
No, and that is why the DD550 uses a plastic head rather than steel. Combinating means seating caps and springs on small non-ferrous parts, and a non-marring face lets you deliver the tap without peening or scarring the component. If the finished core has to go back into a masterkeyed system, a marred cap is a service call later.
3) Do I get a capping block or pin kit with the BEST DD550?
The DD550 is the hammer only, ordered as a single model with no options or sizes to choose. Combinating a core also takes a capping block or press, the pin kit for the keyway you are working, and a follower. Those are separate DD Series service equipment items and have to be ordered on their own.
4) How big is the head on the BEST DD550 combinating hammer?
The head measures 1 x 1-1/4 x 2-1/4 inches. That is a small bench head, sized for tapping core caps and pin components on a keying bench, not for driving strikes or frame work. If you are looking for a general-purpose install hammer for hanging hardware, this is the wrong tool.
5) Is the BEST DD550 hammer something a locksmith needs, or can a property maintenance tech use it?
It is a bench tool for whoever actually pins cores. If your facility keys its own BEST small format interchangeable cores in-house, an in-house maintenance or security shop uses it the same way a locksmith does. If you send cores out to be keyed, you do not need it. The DD550 does no work on the door itself, only at the keying bench.
