A general-purpose workbench lives or dies on how well it holds material still. You can have a flat top and solid legs, but if you are chasing a board with one hand while trying to plane or sand with the other, you are fighting the bench. Good workholding is not about buying every accessory. It is about covering three jobs: holding flat stock down, holding boards on edge or on end, and holding odd shapes without damaging them.

Face vise vs. end vise: pick one to start
If your bench has no vise at all, this is the first upgrade that actually changes how you work. A face vise mounts on the front and clamps boards for edge work, dovetailing, and general assembly. A tail vise or wagon vise mounts on the end and works with bench dogs to hold boards flat for planing and sanding.
For a general bench, a 7 to 9-inch wide workbench face vise is the most useful starting point. Look for at least 8 inches of opening capacity and a cast iron body with steel guide rods. Quick-release is worth paying for if you do a lot of repetitive clamping; without it you waste time spinning the handle for every thickness change. A 6-inch vise will work, but you will run out of capacity when holding drawer sides or wider panels vertically.
End vises are more powerful for flattening panels, but they require a square, dog-hole-compatible top and accurate installation. If you add one later, a wagon vise inset into the benchtop needs 2-3/4 to 3-1/2 inches of top thickness to seat properly and avoid racking. Cheaper screw-type tail vises work, but they rack badly if you only clamp on one side of the screw without a dog or spacer on the other side. If your bench is a sheet-goods top under 1-1/2 inches thick, skip the traditional tail vise and use a face vise plus holdfasts and dogs instead.
Failure mode to watch: mounting any vise to particleboard or MDF without reinforcement. The screws will pull and the vise will flex under load. Add a solid hardwood chop and a backing block that spans at least 12 inches, through-bolted with washers, not just lag screws.
Bench dogs and holdfasts: cheap, fast, surprisingly strong
Bench dogs and holdfasts are the low-cost system that makes a plain bench act like a proper workbench. Round dogs fit 3/4-inch or 20mm holes. 3/4-inch is the North American standard and gives you the widest accessory compatibility. 20mm is the Festool/MFT standard – do not mix them unless you drill both.
Plastic or brass dogs are fine for planing stops, but they shear or bend if you hammer against them. Steel dogs with a spring-loaded face are better for heavy hand-planing. Keep at least four dogs: two for the vise and two as stops.
Holdfasts are the most underrated accessory. A forged steel bench holdfast drops into a 3/4-inch hole and locks with one hammer blow on the top, releases with a blow on the back. No threads, no moving parts. They will hold a board for sanding, routing, or chisel work in about three seconds. They need a top that is 2-1/4 to 3-1/2 inches thick to wedge correctly. Too thin and they slip; too thick (over 4 inches) and many commercial holdfasts will not reach deep enough to bite. Cast iron holdfasts look similar but are brittle – they crack at the bend instead of flexing. Buy forged steel.
Trade-off: holdfasts need firm hits and they will dent softwoods if you clamp directly on the work. Use a scrap pad under the foot. They also require holes through your top, which some people resist drilling in a nice bench. Drill them anyway. A row of holes 4 inches on center down the middle and one row along the front edge covers 90 percent of tasks.
Clamps that actually work on a bench
You do not need a wall of specialty clamps. For bench work, three types cover almost everything.
F-style bar clamps in 12-inch and 24-inch lengths are your general assembly and hold-down clamps. Get ones with a throat depth of at least 2-1/2 inches and a clamping force around 300-600 lbs. The cheap stamped-bar versions flex and the clutch slips under vibration from sanding. Cast or ductile iron heads with a proper clutch plate are noticeably better.
Bench-specific hold-down clamps that fit into dog holes – like Bessey-style auto-adjust toggle clamps or screw-down hold-downs – are faster than reaching for a C-clamp every time. They apply vertical pressure exactly where you need it and stay out of the tool path. For track saw or router work, a pair of bench dog hole clamps that slide into 3/4-inch or 20mm holes will hold a guide rail or workpiece without hanging over the bench edge.
C-clamps and spring clamps have a place for small parts and jigs, but avoid using them as your primary bench hold-downs. Their small foot mars wood and their shallow throat limits where you can place them. If you keep them, choose 3-inch and 4-inch sizes with swivel pads.
Failure mode: over-clamping. On softwoods like pine or cedar, 150 lbs of force will already leave jaw marks. Tighten just until the work does not move when you push it with your palm. More torque does not equal more safety, it just crushes fibers.
Non-slip accessories and surface holding
Not every job needs a vise. For sanding, finishing, and light routing, friction is enough.
A non-slip router mat or bench mat made from open-weave rubber gives surprising grip. Put your panel on it and it will resist sliding from hand pressure alone. It costs less than one clamp and saves time for quick tasks. It does not hold against a hand plane – you still need a dog or holdfast for that much lateral force.
Bench cookies or riser pucks are the same idea but lift the work 3/4 to 1 inch off the bench. That clearance lets you sand or finish an edge without hitting the bench top, and lets you saw without cutting into the top. The rubber ring on top grips while the bottom stays put.
For odd shapes, consider a simple bench hook and a planing stop. A bench hook is just a board with cleats on top and bottom that hooks over the bench edge. It takes all the lateral force when you saw or chisel to a line, and you can make one in 15 minutes from scrap. A shop-made planing stop – a strip of hardwood with a 1/8-inch lip – screwed or wedged into a groove near the end of the bench does what a metal dog does for a fraction of the cost.
What to buy first: a comparison
Do not buy bundles. Start with the system that matches what you do most. If you do hand tool work, prioritize dogs and holdfasts. If you do power tool assembly and sanding, prioritize clamps and mats.
| Accessory | Best For | Typical Cost | Bench Requirement | Limitation |
|---|---|---|---|---|
| Face Vise (7-9″) | Holding boards on edge, dovetails, long stock | $90 – $220 | Solid front apron, 1-1/2″+ top, backing block | Slow without quick-release, needs install |
| Holdfasts (pair, forged) | Fast vertical hold for sanding, chiseling, routing | $35 – $65 for two | 2-1/4″ to 3-1/2″ top, 3/4″ holes | Can dent work, needs hammer blow |
| Bench Dogs (4 pack) | Planing and jointing with vise or stop | $15 – $40 | 3/4″ or 20mm dog holes | Plastic bends, steel can mar edges |
| Dog-Hole Hold-Down Clamps | Track saw, router, repetitive parts | $25 – $55 each | Matching dog hole diameter | Limited opening, 2-3″ capacity |
| F-Style Bar Clamps (12″/24″) | Assembly, edge gluing, jig holding | $12 – $30 each | None | Slow to set, can flex if cheap |
| Non-Slip Mat / Bench Cookies | Sanding, finishing, light routing | $12 – $25 | Flat bench | No lateral hold for planing |
A sensible starter kit for a 5 to 6-foot general bench is: one face vise, two forged holdfasts, four steel bench dogs, two 12-inch and two 24-inch F-clamps, and one non-slip mat. That covers a board held flat, on edge, on end, and held up for finishing, without a wagon vise or a full set of dog holes. You can add a tail vise later if you find yourself hand-planing panels wider than 12 inches every week. If you do not, you just saved $150 and hours of installation.
Installation and safety notes
Layout matters more than brand. Keep dog holes at least 2 inches from any edge to prevent blowout, and chamfer the top of each hole with sandpaper so dogs slide without catching. If you drill into a torsion-box or hollow-core top, glue in a hardwood dowel block or dog-hole insert first – holdfasts will never wedge in air.
Keep holdfast shafts lightly oiled and free of rust. A rusty shaft sticks and then releases suddenly, which can throw a chisel. When using any clamp near a router or saw path, position the handle and bar on the waste side and check clearance with the tool unplugged before you cut. And never use a bench dog as a saw stop at blade height – a spinning blade that hits a steel dog will kick hard. Use a wooden dog or sacrificial stop for cut lines.
You do not need the most expensive vise or a full MFT-style top to get solid workholding. A flat bench with four well-placed dog holes, two holdfasts, and a decent face vise will handle about 80 percent of furniture, trim, and shop projects. Spend the savings on sharp tools and hearing protection.
