Enlarging holes or aligning mismatched feet in metal is the task of a tool well-known as a reamer.

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

The procedure by which this is done is called Reaming and also differs from traditional drilling as it calls for an currently hole, or holes, together a beginning point. A reamer cannot create a hole from scratch, only boost the dimension of existing holes.

Below girlfriend will find a step-by-step guide to reaming in addition to technical recommendations, finest practice advice and information on the range of HMT reamers obtainable 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 also isn’t going to move.Secondly, suspect you currently have a hole you great to enlarge or align choose the most appropriate reamer for the size of feet you need. Because that example, if you space wishing to go from an 8mm feet to a 16mm feet it is not advisable to execute that in one operation. For best results, and to stop tool breakage, enlarge the feet in tiny increments of 2-3mm in ~ a time, making use of the proper sized reamer to execute this.Fit the reamer to your drive tool.When utilizing a Holemaker an innovation 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 installation an ImpactaMag reamer come a magnet drill simply insert right into the arbor and also tighten lar screws.Insert reamer right into the hole to be enlarged. VersaDrive and also ImpactaMag reamers are Tapered reamers, otherwise recognized as leg reamers, and will self centre many thanks to your sloping, tapered sides. (Reamers offered in a magnet drill have the right to only me centre with the magnet turned turn off so the drill deserve to move come the exactly position.)When ready, slightly withdraw the reamer so it is no in call with the sides of the hole and start it spinning.Start the cut, using steady feed pressure throughout the operation.Once the reamer has reached the widest allude the cut is complete, and the reamer can be stopped and also withdrawn.

Best practice advice:

Check the minimum torque need for the device in use.Apply firm, secure feed press throughout the cut, applying the feed an extremely slowly and also cautiously throughout the an initial 1mm of cut.To maximise device life execute not attempt to rise the existing hole diameter past 2-3mm. If a larger, finished hole size is required, then the next size reamer need to be used to ‘step up’ till the finished hole diameter is reached.Avoid lateral activity or tilting which can cause damage come the toolEnsure regular application of top quality cooling lubricant, specifically when drilling thick or hardened materials.Flame cut, laser reduced or punched holes may not be possible to ream with an affect wrench. In this case the hole deserve to be reamed out with a sluggish speed Magnet Drill through an ImpactaMag or VersaDrive reamer.Follow accuse to set correct RPM speed. Not correct RPM have the right to lead to negative life or tool breakage.Ensure a debris complimentary surface of sufficient steel thickness for solid magnet hold when Magnet Drilling.Regularly examine that Magnet Drill slides, handles, arbors and also movable parts have actually not vibrated loosened over time.For more quickly performance use on impact wrenches and impact drivers.For considerable technical information on recommended speeds and also feeds check out the end of the article.

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

There are numerous reasons why holes should be modified ~ they have actually been created – most commonly these can incorporate specification changes, a readjust in the type of fixings to be used, or even simply a measurement mistake at some phase of the process.

Whatever the factor for enlarging a hole though, it has traditionally been daunting to execute accurately ~ above site and also away indigenous static, precision milling and also drilling machines, particularly in tough materials such together steel.

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

It to be a desire to administer a systems to these difficulties that led us to produce two brand new products - go into the VersaDrive and ImpactaMag variety of construction and fabrication reamers.

VersaDrive affect Reamers


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

Featuring a specially draft 6 flute cut geometry and Titanium coating, VersaDrive™ Reamers are fully Impact rated and perform more quickly when offered with an influence wrench providing ultimate cut performance through virtually no powertool kickback.

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

Technical rapid guide

For fastest performance use on affect wrenches & influence driversImpact pushed reamers space not recommended because that Flame or Plasma cut holes. Use with a Magnet DrillReamer should be rotating before starting the reduced & stable feed pressure need to be used through the cutFor materials thicker than 20mm use of ImpactaMag reamers is recommended


HMT ImpactaMag Reamer


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

Specially designed cutting geometry allows the device to be supplied in an impact wrench or a Magnet drill. When used in an influence wrench it is secured into a one-of-a-kind adapter an interpretation the tool is easier to control, apply correct feeding rate, and withdraw from the perfect hole, improving tool life. This reamer will likewise fit into a conventional Weldon magnet drill arbor.

The tapered design enables the narrow finish of the ImpactaCut reamer come be gone into into the existing hole and also accurately centred.

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


Ideal for steel erection & leg workIdeal for modifying & enlarging holesSecured straight to the influence WrenchCan be provided with any standard Magnet DrillAvailable in intermediate sizesUnique 6 flute design for faster, smoother cutPrepare holes all set for surroundings of TCB & friction grip bolts


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

The correct tool for the job will depend on the drive tool you are able come use, the dimension of the final hole required and the material you space reaming.

When VersaDrive reamers space the best option:

When using a portable strength tool prefer an affect Driver or influence Wrench and also the last hole size required is below 26mm the VersaDrive affect Reamer would certainly be the encourage option. This tool quickly and also easily fits the VersaDrive selection of quick-change, rapid-lock adapters and also can be offered to enlarge a hole in materials up come 20mm thick.

VersaDrive reamers can likewise be provided with cordless drills and magnet drills or shaft drills so for applications inquiry holes approximately 26mm diameter in materials up come 20mm special VersaDrive reamers are still perfect because that the task.


When ImpactaMag reamers are the best option:

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

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


Many building and also construction specialists will testify. A project on-site or in the workshop can be walk fine till a tiny problem favor a misaligned hole, a poorly drilled hole, or a link hole the is as well small, can put a really expensive spanner in the works.
