Enlarging feet or aligning mismatched holes in steel is the project of a tool recognized as a reamer.

You are watching: When a hole is reamed in metal to size, it is:

The procedure by which this is excellent is referred to as Reaming and differs from traditional drilling together it requires an existing hole, or holes, together a beginning point. A reamer cannot develop a feet from scratch, only increase the dimension of current holes.

Below you will discover a step-by-step guide to reaming together with technical recommendations, finest practice advice and information ~ above the range of HMT reamers accessible and the best situations in i m sorry to use them.

How to enlarge or align (Ream) a hole in metal:


Firstly, ensure that your workpiece is securely fixed and also isn’t going come move.Secondly, suspect you currently have a hole you great to enlarge or align select the most ideal reamer for the size of feet you need. For example, if you space wishing to go from one 8mm feet to a 16mm feet it is no advisable to carry out that in one operation. For ideal results, and also to avoid tool breakage, enlarge the feet in small increments of 2-3mm in ~ a time, utilizing the proper sized reamer to do this.Fit the reamer to your drive tool.When utilizing a Holemaker technology VersaDrive reamer in an influence wrench, magnet drill or SDS drill pick the correct adapter, fit come the journey tool and also insert the reamer.When fitting an ImpactaMag reamer come a magnet drill merely insert right into the arbor and also tighten lar screws.Insert reamer into the hole to be enlarged. VersaDrive and ImpactaMag reamers space Tapered reamers, otherwise known as leg reamers, and will self centre many thanks to their sloping, tapered sides. (Reamers supplied in a magnet drill can only me centre with the magnet turned turn off so the drill have the right to move to the correct position.)When ready, slightly retract the reamer so that is not in call with the sides of the hole and also start it spinning.Start the cut, applying steady feed pressure throughout the operation.Once the reamer has reached the widest suggest the reduced is complete, and the reamer can be stopped and withdrawn.

Best practice advice:

Check the minimum torque requirement for the tool in use.Apply firm, stable feed press throughout the cut, using the feed really slowly and cautiously during the first 1mm that cut.To maximise device life do not effort to boost the existing hole diameter beyond 2-3mm. If a larger, finished hole size is required, climate the following size reamer need to be offered to ‘step up’ till the finished hole diameter is reached.Avoid lateral motion or tilting i beg your pardon can cause damage come the toolEnsure regular application of quality cooling lubricant, particularly when drilling special or hardened materials.Flame cut, laser reduced or punched holes may not be feasible to ream through an influence wrench. In this situation the hole deserve to be reamed out with a slow-moving speed Magnet Drill through an ImpactaMag or VersaDrive reamer.Follow guidelines to set correct RPM speed. Incorrect RPM can lead to bad life or tool breakage.Ensure a debris totally free surface of adequate steel thickness for solid magnet hold when Magnet Drilling.Regularly inspect that Magnet Drill slides, handles, arbors and also movable parts have not vibrated loosened over time.For faster performance usage on affect wrenches and affect drivers.For extensive technical details on recommended speeds and also feeds view the end of the article.

Now you recognize how, why would you desire to ream a hole?

There are many reasons why holes should be modified after ~ they have actually been produced – most generally these can encompass specification changes, a readjust in the kind of fixings to it is in used, or also simply a measure up mistake at some phase of the process.

Whatever the factor for enlarging a hole though, it has traditionally been complicated to perform accurately on site and away native static, precision milling and also drilling machines, particularly in tough materials such together steel.

The inquiry of "how to perform this quickly and correctly" then came to be a actual challenge.

It to be a desire to administer a systems to these challenges that led united state to create two brand new products - get in the VersaDrive and ImpactaMag selection of construction and fabrication reamers.

VersaDrive influence Reamers

VersaDrive reamers space the perfect feet alignment and enlarging tool for metalworkers & stole erectors for keeping the job moving when a hole is misaligned or the incorrect size for the fixing.

Featuring a specially draft 6 flute cutting geometry and Titanium coating, VersaDrive™ Reamers are totally Impact rated and also perform faster when supplied with an influence wrench giving ultimate cut performance through virtually no powertool kickback.

VersaDrive Reamers have actually a patented non-slip, Hex shank suitable for use in any kind of standard 1/2” drill lining for cordless or pistol drills or used with a VersaDrive rapid Lock adapter for usage in a wide variety of powertools such as Magnetic Drills.

HMT ImpactaMag Reamer

The ImpactaMag™ HSS reamer is a unique double-use reamer for enlarging and also aligning holes in metals and also hard materials.

Specially designed cutting geometry allows the tool to be supplied in an influence wrench or a Magnet drill. When provided in an influence wrench the is secured right into a distinct adapter meaning the tool is easier to control, apply correct feed rate, and also withdraw native the perfect hole, improving tool life. This reamer will additionally fit into a traditional Weldon magnet drill arbor.

The tapered design permits the narrow finish of the ImpactaCut reamer to be gone into into the present hole and accurately centred.

The rotary/percussion influence cuts an accurate shavings off each next of the hole, approximately the widest dimension of the reamer.

So exactly how do you understand which one is because that you?

The correct device for the project will rely on the drive device you space able to use, the size of the last hole required and also the product you room reaming.

When VersaDrive reamers space the ideal option:

When using a portable power tool like an influence Driver or influence Wrench and the final hole size compelled is listed below 26mm the VersaDrive influence Reamer would be the recommended option. This device quickly and also easily fits the VersaDrive selection of quick-change, rapid-lock adapters and also can be supplied to enlarge a hole in materials up come 20mm thick.

VersaDrive reamers can likewise be provided with cordless drills and also magnet drills or tower drills so because that applications request holes up to 26mm diameter in products up come 20mm special VersaDrive reamers space still perfect for the task.

 

When ImpactaMag reamers space the finest option:

If you are using a magnet drill there is no an adapter, require a hole size between 26-39mm or have material better than 20mm thick then the ImpactaMag Reamer would certainly be the encourage option.

With it’s Weldon shank the ImpactaMag reamer will certainly fit directly into a traditional 19.05mm arbor whilst it’s building makes it perfect to tackle thicker materials, over 20mm in depth.

 

Many building and construction professionals will testify. A job on-site or in the workshop have the right to be going fine till a small problem prefer a misaligned hole, a poorly drilled hole, or a link hole that is also small, can put a very expensive spanner in the works.
