Dayton 31LZ69 5" Machine Vise Fixed Base

SKU CH-SAQZ-6HN4V

A 5-inch machine vise with a fixed base, precision ground for stability and 0.0125 inch jaw deflection at 33 lb

  • Precision base enables accurate work
  • Fully ground base provides stability
  • Jaw deflection 0.0125 in at 33 lb holds small parts
  • Throat depth 1 29/32 in accommodates larger pieces
  • Fixed bed 0.008 in thick supports delicate projects

Precision 5" Machine Vise

The Dayton 31LZ69 5" Machine Vise provides a fully ground fixed base for accurate workholding in metalworking and machining tasks. Its rigid construction supports precise alignment when clamping small components. This tool suits machinists and fabricators who need repeatable positioning on a benchtop.

Upgrade from Swivel-Base Models

A fixed base eliminates the rotational play found on swivel vises, improving stability during milling or drilling operations. The jump is worthwhile when workpieces require consistent orientation without re-zeroing. Buyers who need rotational adjustment for angled cuts will find this design limiting.

Sustained Clamping Performance

Jaw deflection measures .0125 in at 33 lb, indicating minimal movement under continuous load. The .008 in thick base resists flex during extended machining cycles. Throat depth of 1 29/32 in. accommodates taller workpieces without compromising rigidity over time.
