HMH's Standard is the vise that started the revolution in precision machined rotary vises more than 30 years ago. Since then, HMH has updated it with an improved chassis/bearing system for better collet support, better rotation, and infinite head angle adjustment. All parts are precision machined using top quality stainless and tool steels and brass. The Standard's features include: infinite head angle adjustment, longest collet & tying platform for better tying, interchangeable jaws (comes with the Omni jaws accepting hook sizes 20 to 2/0), ultra smooth 360° rotary action, exclusive disc drag rotary tension adjustment; large, comfort grip locking cam lever; fast, one hand operation to clamp hooks or adjust hook wire size, double spring material clip, and a sculpted heavy iron pedestal base. Comes with neoprene vise pouch. Lifetime Guarantee.
