Value Collection 428-99991 Machine Vise 6 in Jaw Width

Product Description

The VALUE COLLECTION 428-99991 is a manual machine vise designed for horizontal workholding on milling machines, drill presses, and similar stationary machining equipment. Built from ductile iron, this single-station vise delivers a 6-inch jaw width and a maximum jaw opening capacity of 5.5 inches, making it well suited for securing medium to large workpieces during drilling, milling, or grinding operations. With a rated load capacity of 6,600 pounds and a precision-ground construction, the 428-99991 provides the rigidity and repeatability that machinists and toolroom technicians require on production and maintenance shop floors.

This vise is intended for stationary-base horizontal mounting and is appropriate for use in machine shops, maintenance facilities, and vocational or industrial training environments. The 17-inch overall length and 6.3-inch base width provide a stable footprint on standard mill tables and drill press tables. Manual operation makes it straightforward to set up and clamp without auxiliary power or hydraulic lines. It is installed and adjusted by machinists, tool and die workers, and maintenance mechanics performing general metalworking tasks.

Key Features

• 6-inch jaw width accommodates a wide range of workpiece sizes
• Maximum jaw opening of 5.5 inches for versatile stock clamping
• Ductile iron construction resists cracking under high clamping loads
• Rated load capacity of 6,600 pounds for secure, rigid workholding
• Precision designation ensures consistent jaw alignment and repeatability
• Stationary horizontal base for direct table mounting without swivel adjustment

Compatibility

Designed as an OEM-style stationary machine vise suitable for standard T-slot mill tables, drill press tables, and similar horizontal machining platforms that accept a base footprint of approximately 15.35 inches in length and 6.3 inches in width.

Installation Notes

Installation is performed by a qualified machinist or maintenance mechanic. Power down and lock out the machine before mounting or adjusting the vise on any machine table. Secure the vise to the table using appropriate T-bolts and clamps sized to match the table slots, and verify that all fasteners are fully tightened before applying any clamping load to a workpiece. Inspect jaw faces and the base seating surface for burrs or debris before mounting to ensure accurate, flat seating.
