Q: What makes S2 steel better than regular tool steel?
A: S2 alloy steel is a shock-resistant tool steel heat-treated to HRC60 hardness, making it significantly tougher and more wear-resistant than standard chrome vanadium or carbon steel bits. This means less stripping, longer service life, and reliable performance on repeated use.
Q: Can these bits be used for woodworking and furniture assembly?
A: Absolutely. These hex Allen bits are ideal for woodworking projects, flat-pack furniture assembly, bicycle maintenance, appliance repair, and general mechanical work wherever hex-head fasteners are used.
