Yes, you'll also need a chain whip to hold the cassette body still while you turn the lockring tool, since the freehub will otherwise just spin along with the tool instead of loosening.

No, this standard version is meant for wheels with a quick-release style hub, where you typically thread the wheel's skewer back through the tool to hold it securely in the lockring's splines while you apply force; the through axle version is built differently to seat properly in thru-axle hub bores.

It's made from high-quality carbon steel with a hardened plating finish, using a thickened 4mm steel main rod that's heat-treated to resist bending or deformation under the high torque needed to loosen a tight lockring.

Cassette removal is a very manageable home maintenance job with the right tools, so this is well suited to a home mechanic replacing a worn cassette, cleaning the freehub, or swapping gearing, not just professional shops.

Cassette lockrings are usually torqued on quite tight, so expect to apply firm, steady force with a long-handled adjustable wrench; the tool's widened, overmolded handle and thick steel rod are built to handle that load without flexing.
