The keys must all reach the same depth. A shallow key stays proud and does nothing; an over-driven key can split a thin wall, so the matching setting tool and stroke are part of the specification.
Material: SUS304 Stainless Steel.
Use the dedicated tool, since a generic driver cannot control key depth.
