When precision is non-negotiable, you need tools that deliver consistency, stability, and alignment down to fractions of a thousandth. That’s where the new Omni Adjustable Rigid Reamer Holder from Manson comes in—a Reamer Holder designed to take your reaming to the next level. And to make sure you understand exactly how to get the most out of it, Manson has partnered with none other than Dustin Drews. He shows off this tool in the below video, walking through set-up and proper use.

What Is the Omni Adjustable Rigid Reamer Holder?

The Omni Adjustable Rigid Reamer Holder is a purpose-built accessory for precision machining, specifically reaming. Here’s what makes this Reamer Holder special:

• It’s rigid, not floating—this rigidity is key to preventing chatter and deflection during machining. 
• Adjustable in multiple axes: it allows micro-adjustments radially (X & Y axes) and angularly, so you can correct tilt or misalignment from the collet or the tool post. The result: the reamer can be made dead-true relative to the spindle. 
• Includes an indicating jig to align the reamer precisely to the spindle bore while held in the holder. (Note: the Interapid .0001/10th indicators shown in the instructions are not included.) 
• Designed to be used on the carriage of a lathe rather than the tailstock. The carriage gives you a far more stable, repeatable setup; tailstocks suffer from sag, non-repeatability, and often can’t be aligned accurately enough for high-end reaming work. 

Features & Advantages of This Reamer Holder

Here are some specific benefits when you use this Reamer Holder:

Advantage	Why It Matters
Rigid stability	Minimizes chatter, which improves surface finish and prolongs tool life.
Micro-adjustable in all planes	Allows you to eliminate runout (both angular and radial), which means more concentric chambers or holes.
No side load	Reduces the risk of oversized chambers or deformation during reaming.
No droop or flex	Prevents scratches, galling, or subtle errors caused by bending of the tool or holder.
Repeatability	Once set, you can expect consistent results every time which is very important if you’re batch-producing or comparing barrels, etc.

In short: eliminate runout in the barrel, align perfectly, and cut with zero flex. If you’re serious about tight tolerances, this Reamer Holder is built to deliver.

Why Dustin Drews & Manson’s Partnership Matters

Manson Precision Reamers has deep roots in high-precision chamber reaming and gunsmithing tooling. By collaborating with Dustin Drews, a respected machinist and content creator,they ensure that this Reamer Holder isn’t just theoretically excellent on paper but works in real-world setups. In Dustin’s YouTube video, he walks you through setting up the holder, indicating the reamer, adjusting it in all relevant axes, and finally doing reaming with minimal runout. His perspective helps bridge the gap between factory specs and what you’ll experience on your own lathe.

This partnership means you’re not just buying a tool, you’re getting the cumulative knowledge of people who build tools and people who use them at a high level. That’s a big deal for anyone chasing accuracy in reaming.

How to Use the Omni Adjustable Rigid Reamer Holder — Key Steps (As Seen from Dustin Drews’ Walkthrough)

To get the best results with this Reamer Holder, as shown by Dustin Drews in the included video:

1. Mount the Reamer Holder on the Lathe Carriage — Ensure your setup is stable; the carriage is more reliable than the tailstock for this kind of precision work.
2. Indicate the Reamer — Use the included indicating jig to bring the reamer into perfect concentric alignment with the spindle bore. Check for both angular and radial runout.
3. Adjust Micro-Levels — The Omni holder allows for fine-tune corrections in X, Y, and angular planes. Make adjustments until your readings show near-zero runout.
4. Rigid Clamping — Once aligned, clamp firmly to eliminate movement under load. The rigidity is part of the value proposition.
5. Proceed with Reaming — With everything aligned and rigid, ream as required. Expect smoother cuts, better finishes, consistent chamber sizes, and fewer issues like chatter or side loading.

Dustin’s video demo is especially helpful because he shows the tweaks and checks most people might miss—those small adjustments make all the difference. 

Pricing, Ordering, and What’s Included

Some practical details:

• The Omni Adjustable Rigid Reamer Holder is priced at US$800. mansonreamers.com
• It is made in the USA, by Drews Precision in Bison, South Dakota. mansonreamers.com
• Comes with the indicating jig. Indicators (Interapid .0001/10th) shown in the instructions are not included. mansonreamers.com
• Dimensions and weight are modest (approx. 2 × 2 × 2 in, 2 lbs) which makes it manageable in most machining setups. mansonreamers.com

Who Needs This Reamer Holder?

If you fall in any of these categories, this Reamer Holder is for you:

• Gunsmiths or barrel makers chasing precise chamber dimensions.
• Machinists working with tight tolerances where runout, chatter, or alignment errors show up in rejects or inconsistent work.
• Anyone moving from hobby machining to professional levels, or upgrading tooling to reduce errors.
• Shops that want repeatability across multiple parts or barrels.

If your work demands more than “good enough,” the Omni Adjustable Rigid Reamer Holder is an investment in precision.

Summing Up

In precision reaming, what separates excellent results from mediocre ones is control: control over alignment, runout, stability, and consistency. The Omni Adjustable Rigid Reamer Holder from Manson delivers on all of those fronts. With its rigid construction, full-plane adjustability, and purpose-built design (including the included jig), it’s built to ensure your reamer stays true, your chambers stay concentric, and your finishes stay clean.

And thanks to the partnership with Dustin Drews, you’re not left to figure it out alone—you get a how-to/resource that shows you what “ideal setup” looks like, where people commonly make mistakes, and how to adjust to get the best out of this Reamer Holder. Whether you’re working on custom barrels, optimizing production, or simply want your machining work to reflect your skills without being limited by tooling, this could be a transformative tool.
