Grip Harder.
Cut Harder.

Custom fixtures, jigs, and specialty chucking designed and built in-house — so your parts hold tight, your cycle times drop, and your bottleneck stops being the setup.

Specialty Workholding

The Fixture Is the Bottleneck. Most Shops Don't See It.

You can have the best machines on the floor and still lose hours a week to setup fiddling, chatter you can't cut past, or parts that shift mid-operation. The fix usually isn't a better machine — it's better workholding.

For over 30 years, Dun-Rite has designed and built custom fixtures, jigs, and specialty chucking for the parts off-the-shelf solutions can't handle. Grip harder, cut harder, run faster. That's the whole game.

What We Build

Three Ways We Hold Your Work.

Custom Fixtures
Purpose-built fixtures for specific parts, operations, or part families. Designed around your geometry, your cycle times, and your tolerances.
Jigs
Drilling, boring, and inspection jigs built for repeatability. Setup that's identical every time, every shift, every operator.
Specialty Chucking & Clamping
Custom chucking solutions for parts that off-the-shelf vises and chucks can't grip securely — thin-walled components, complex geometries, exotic materials.

Why Workholding Matters More Than Most Shops Admit.

The fixture decides how hard you can cut, how consistently the part lands, and how fast you can turn setups. Get it right and your cycle times drop, your scrap rate drops, and your operator variability disappears. Get it wrong and you're under-cutting, chasing chatter, or reworking parts that shifted mid-op.

We design workholding that lets you machine aggressively without sacrificing repeatability. Same setup, same result — first part, hundredth part, thousandth part. And because we design the fixture and machine your parts under one roof, there's no finger-pointing between vendors when something needs to change.

Specializing in tight tolerances.
Complex Parts

Thin walls, odd geometries, or features that off-the-shelf workholding can't grip without distortion. We design around the part, not the other way around.

Tight-Tolerance Jobs

Aerospace, medical, and precision industrial work where a 0.0005" shift is a scrap part. Fixtures that hold position under cutting forces, every time.

Production Consistency

High-volume jobs where cycle time and repeatability drive cost-per-part. Quick-change fixturing, repeatable locating, and designs that scale with your run size.

Where It Pays Off

Where Specialty Workholding Earns Its Keep.
