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

You are watching: Hole is reamed in metal to size

The procedure by i m sorry this is excellent is referred to as Reaming and also differs from classic drilling together it requires an present hole, or holes, together a starting point. A reamer cannot create a feet from scratch, only rise the dimension of current holes.

Below girlfriend will uncover a step-by-step guide to reaming in addition to technical recommendations, ideal practice advice and information top top the variety of HMT reamers accessible and the ideal situations in which to usage them.



How come enlarge or align (Ream) a feet in metal:

Firstly, ensure the your workpiece is securely fixed and isn’t going to move.Secondly, suspect you currently have a feet you great to enlarge or align pick the most proper reamer for the size of feet you need. For example, if you space wishing to go from one 8mm hole to a 16mm feet it is not advisable to do that in one operation. For ideal results, and to stop tool breakage, enlarge the hole in little increments of 2-3mm at a time, using the ideal sized reamer to perform this.Fit the reamer to your drive tool.When utilizing a Holemaker modern technology VersaDrive reamer in an influence wrench, magnet drill or SDS drill choose the exactly adapter, fit come the drive tool and also insert the reamer.When installation an ImpactaMag reamer come a magnet drill just insert right into the arbor and also tighten grub screws.Insert reamer into the feet to be enlarged. VersaDrive and ImpactaMag reamers are Tapered reamers, otherwise recognized as bridge reamers, and will me centre many thanks to their sloping, tapered sides. (Reamers provided in a magnet drill can only self centre through the magnet turned turn off so the drill have the right to move come the correct position.)When ready, slightly withdraw the reamer so the is no in call with the political parties of the hole and start it spinning.Start the cut, applying steady feed pressure throughout the operation.Once the reamer has actually reached that is widest allude the cut is complete, and the reamer deserve to be stopped and also withdrawn.

Best practice advice:

Check the minimum torque necessity for the tool in use.Apply firm, steady feed press throughout the cut, applying the feed really slowly and cautiously throughout the first 1mm the cut.To maximise device life carry out not effort to increase the existing feet diameter past 2-3mm. If a larger, perfect hole size is required, then the next size reamer must be supplied to ‘step up’ until the finished feet diameter is reached.Avoid lateral motion or tilting i beg your pardon can cause damage to the toolEnsure continuous application of top quality cooling lubricant, especially when drilling thick or hardened materials.Flame cut, laser reduced or punched holes may not be feasible to ream through an affect wrench. In this instance the hole have the right to be reamed out through a slow-moving speed Magnet Drill with an ImpactaMag or VersaDrive reamer.Follow guidelines to set correct RPM speed. Incorrect RPM deserve to lead to negative life or device breakage.Ensure a debris cost-free surface of enough steel thickness for strong magnet hold when Magnet Drilling.Regularly inspect that Magnet Drill slides, handles, arbors and movable parts have actually not vibrated loosened over time.For fastest performance usage on impact wrenches and impact drivers.For comprehensive technical details on recommended speeds and feeds watch the end of the article.

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

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

Whatever the reason for enlarging a feet though, it has traditionally been an overwhelming to carry out accurately top top site and away from static, precision milling and drilling machines, particularly in tough materials such together steel.

The concern of "how to execute this quickly and also correctly" then became a genuine challenge.

It to be a desire to carry out a equipment to these challenges that led us to create two brand brand-new products - go into the VersaDrive and ImpactaMag selection of construction and also fabrication reamers.

VersaDrive affect Reamers


VersaDrive reamers space the perfect feet alignment and also enlarging device for metalworkers & steel erectors for keeping the job moving when a hole is misaligned or the incorrect dimension for the fixing.

Featuring a specially design 6 flute cut geometry and also Titanium coating, VersaDrive™ Reamers are fully Impact rated and perform faster when provided with an influence wrench providing ultimate cut performance with virtually no powertool kickback.

VersaDrive Reamers have a patented non-slip, Hex shank suitable for usage in any type of standard 1/2” drill lining for cordless or pistol drills or offered with a VersaDrive fast Lock adapter for usage in a wide range of powertools such as Magnetic Drills.

Use v a Magnet DrillReamer must be rotating before beginning the cut & stable feed pressure must be provided through the cutFor products thicker 보다 20mm usage of ImpactaMag reamers is recommended


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 cut geometry enables the tool to be supplied in an impact wrench or a Magnet drill. When used in an affect wrench the is secured into a one-of-a-kind adapter meaning the tool is easier to control, use correct feed rate, and withdraw indigenous the finished hole, improving tool life. This reamer will likewise fit right into a traditional Weldon magnet drill arbor.

The tapered design allows the narrow end of the ImpactaCut reamer come be gotten in into the currently hole and also accurately centred.

The rotary/percussion influence cuts an exact shavings off each next of the hole, as much as the widest dimension of the reamer.

So just how do you understand which one is for you?

The correct tool for the job will rely on the drive tool you room able come use, the dimension of the last hole required and also the product you are reaming.

When VersaDrive reamers are the ideal option:

When using a portable power tool favor an affect Driver or impact Wrench and the last hole size forced is below 26mm the VersaDrive affect Reamer would be the recommended option. This device quickly and easily fits the VersaDrive variety of quick-change, rapid-lock adapters and can be offered to enlarge a feet in products up come 20mm thick.

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


When ImpactaMag reamers space the best option:

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

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


Many building and also construction specialists will testify. A task on-site or in the workshop can be walk fine until a small problem favor a misaligned hole, a poorly drilled hole, or a link hole that is also small, deserve to put a an extremely expensive spanner in the works.
