Kurt HD690 | 9" Opening 6" Vise

Description

The Kurt HD690 is a heavy duty bench vise made for precision machining and repeatable clamping. With a full 9 inch opening between standard jaw plates and verified Kurt 6 vise jaw dimensions, the HD690 delivers high clamp force with minimal body deflection. Its wider, taller stationary jaw and “pull-type” body is designed to reduce stress and improve stiffness so setups remain flat and accurate under load. The vise accepts HD platform quick change movable jaws and uses sine keys for positive alignment; Groove Lock workstop and jaw are included. Narrower body width allows more vises per work envelope while maintaining a matched body height tolerance of ±0.0005". Typical shipping weight: 75 lbs.

Product Features and Benefits

Large 9" jaw opening for oversized parts

The Kurt HD690 full 9" opening expands capacity for larger workpieces while preserving rigid clamping and precise alignment for repetitive operations.

Optimized stationary jaw & low deflection body

Kurt 6 vise jaw dimensions are wider, the taller stationary jaw with four top bolts reduces stationary jaw deflection, and the pull type body design lowers internal stress for more accurate clamping under load.

HD quick change movable jaws & Groove Lock workstop

The 6-inch Kurt vise features an HD platform with quick-change jaws, making holding odd shapes fast and repeatable; a Groove Lock workstop and jaw are included to simplify fixturing and datum control.

Mounting compatibility and installation accuracy

Bolts and locates directly to standard grid plates and uses sine keys for alignment; body height matched to ±0.0005" for precision setups.
