Pinsir is not the best, but a reliable SR user in NU. Although not quite as bulky like Rhydon or as fast as Archeops, Pinsir can provide some valuable offensive presence.
Stealth Rock crushes Flying-type switch-ins, like Archeops, and Fire-types, such as Magmortar.
X-Scissor is nice STAB and deals a lot of damage.
Earthquake is always a nice move on any Physical attacker. It helps deal with Levitate 'mons, such as Weezing and Rotom. Stone Edge and Rock Slide is used mainly to deal with Flying-types (mainly Xatu, which might try to predict the SR and switch-in) and other leads, like Archeops.
Toxic is a nice move to deal with walls. Close Combat is a nice move to hit Rock-types, like Rhydon, harder than if Earthquake was used. Knock Off allows it to cripple threats by removing their item.
