Sneed's Shredder

Sneed's Shredder is the second boss you will encounter in the Deadmines. It is a level 20 mechanical shredder, piloted by Sneed, a level 20 elite goblin who is ejected from his shredder after it is defeated. His room is filled with Goblin Woodcarver mobs, which should be cleared before you pull Sneed's Shredder.
Overview
Tank
Focus on doing as much threat as possible on the boss, so the DPS can go all-out. Maintain threat to avoid [Distracting Pain] debuff from being applied to other party members. Note that after Sneed's Shredder crumbles, Sneed will appear and have a new threat table. [Taunt] Sneed and get as much threat as you can on him. Sneed casts [Disarm], so be ready to use abilities that don't require a weapon in order to maintain threat.
Damage Dealers
After Sneed's Shredder crumbles, focus on dealing as much damage as possible to Sneed.
Healers
This fight is a tank and spank so you should focus your healing on the tank.
