What to Look for When Buying a Used ERON Vise
ERON vises are built from high-tensile Japanese cast iron with hardened jaws, acme-threaded lead screws, and precision-ground mounting and clamping surfaces. Here is what to inspect on used units.
Check jaw condition and alignment. Inspect both fixed and movable jaw faces for chips, cracks, gouges, or excessive wear. Close the jaws on a precision parallel and check for even contact using a feeler gauge. ERON vises ship with replaceable jaw plates, so worn jaws can often be swapped rather than scrapping the vise.
Test the lead screw and nut for backlash. The acme-threaded lead screw is the primary wear item on any vise. Clamp lightly on a workpiece and push/pull the movable jaw to detect play. Excessive backlash indicates a worn lead screw or nut. ERON vises use a brass alloy nut for low friction and long life.
Inspect the body and slide for wear. Check the slide channel for scoring or looseness. The movable jaw should glide smoothly with no side-to-side play. On Lock-Tight and hydraulic models, verify that the lock-down mechanism engages positively.
Verify the base and mounting surfaces. The base must be flat and free of nicks that would prevent square seating. On swivel-base models, verify smooth rotation and firm locking. On drill press vises, inspect mounting bolt slots for elongation.
ERON Milling Machine Vises
Lock-Tight Series
The Lock-Tight milling vises (including models LT60 and #200) are ERON's most recognized milling products. These vises feature precision-ground fixed and movable jaws, heavy cast-iron bodies, acme-threaded screws, and a positive lock-down mechanism that prevents jaw lift during heavy cuts. Available in 6-inch and 8-inch jaw widths, Lock-Tight vises have also been distributed under the SPI (Swiss Precision Instruments) brand name. These are the most commonly traded ERON vises on the used market.
E-9107 F-Type & E-475 Hydraulic
The E-9107 F-Type milling vises provide heavy-duty workholding for production milling environments with rigid cast-iron construction and precision-ground surfaces. The E-475 Lock-Tight Hydraulic Machine Vise MK3 adds hydraulic clamping for consistent, high-force workholding without manual effort, ideal for CNC milling operations where repeatability and clamping force consistency are critical.
ERON Machinist Bench Vises
The E-504 Medio machinist bench vises are available with 4-inch (100 mm), 5-inch (126 mm), and 6-inch (150 mm) jaw widths. These vises feature cast-iron bodies, replaceable hardened jaw plates, and acme-threaded lead screws for smooth, powerful clamping. The larger #75, #100, #150, and #200 bench vises cover 3-inch through 8-inch jaw widths in progressively heavier castings. ERON bench vises are known for thick slide channels that double as anvil surfaces.
ERON Drill Press Vises
The E-103 series (E-103-5, E-103-6) drill press vises feature acme-threaded screws for smooth operation and powerful clamping in 5-inch and 6-inch jaw widths. The P250AS adds an angle adjustment plus a 360-degree rotating swivel base with ground top and side faces. The 304T and 303T drilling machine vises are built from rugged cast iron with steel jaw plates featuring horizontal and vertical grooves for holding round stock. All ERON drill press vises are designed to be turned on their sides or stood on end for versatile workpiece positioning.
ERON Precision Accessories
ERON's accessory line includes the U-125 two-piece machine vises that allow 100% table utilization by clamping extra-long workpieces with independent jaw sections. Vee blocks (Type A and Type B) provide accurate V-groove support for round stock inspection and machining setups. Levelling blocks (Types A, AN, B, C, and G) serve precision levelling and alignment applications. Cast iron surface plates provide stable, flat reference surfaces for layout and inspection work.
How to Sell Your Used ERON Equipment
ERON vises hold solid resale value thanks to Japanese build quality, cast-iron durability, and a loyal following among machinists who prefer ERON over mass-market alternatives. Lock-Tight milling vises, E-475 hydraulic models, and larger bench vises (#150, #200) are in particularly high demand.

Frequently Asked Questions About Used ERON Vises
Are used ERON vises reliable?
Yes. ERON vises are made in Japan from high-tensile cast iron with hardened jaws and precision-ground surfaces. Their build quality is widely regarded as superior to most Asian-manufactured alternatives. Well-maintained ERON vises routinely serve 30 years or more.
What is the difference between ERON and SPI Lock-Tight vises?
They are the same product. SPI (Swiss Precision Instruments) distributed certain ERON milling vises under the Lock-Tight brand name. Used vises may carry ERON, SPI, or Lock-Tight markings depending on the era and distribution channel. Quality and construction are identical regardless of branding.
What should I inspect before buying a used ERON vise?
Check jaw condition and alignment (close on a parallel and look for gaps), test lead screw backlash, inspect the slide channel for wear or scoring, verify that the base is flat and free of nicks, and confirm that all locking mechanisms engage positively.
Can I get replacement jaws for an ERON vise?
ERON vises use replaceable hardened jaw plates. Replacement jaws can be sourced through ERON distributors or third-party suppliers that carry compatible jaw inserts. In many cases, standard-width replacement jaws from other manufacturers will also fit.
What industries use ERON vises?
ERON vises serve machine shops, toolrooms, job shops, manufacturing facilities, maintenance and repair operations, educational institutions, and hobbyist workshops. The milling and hydraulic vises are used on both manual and CNC milling machines.
What ERON models hold their value best?
Lock-Tight milling machine vises, E-475 hydraulic vises, and larger bench vises (#150 and #200 with 6-inch and 8-inch jaws) maintain the strongest resale values. Vintage ERON vises in good condition are particularly sought after. Call (844) 478-8181 for valuations.
