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

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

The process by i beg your pardon this is done is called Reaming and also differs from timeless drilling together it requires an existing hole, or holes, together a starting point. A reamer cannot develop a hole from scratch, only rise the size of existing holes.

Below friend will uncover a step-by-step guide to reaming in addition to technical recommendations, best practice advice and information top top the selection of HMT reamers available and the best situations in which to usage 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 feet you wish to enlarge or align pick the most appropriate reamer because that the size of hole you need. Because that example, if you space wishing to walk from an 8mm feet to a 16mm feet it is not advisable to execute that in one operation. For best results, and also to stop tool breakage, enlarge the feet in small increments that 2-3mm at a time, utilizing the proper sized reamer to perform this.Fit the reamer to your drive tool.When utilizing a Holemaker technology VersaDrive reamer in an influence wrench, magnet drill or SDS drill select the correct adapter, fit to the journey tool and also insert the reamer.When fitting an ImpactaMag reamer come a magnet drill just insert into the arbor and tighten lar screws.Insert reamer right into the feet to it is in enlarged. VersaDrive and also ImpactaMag reamers space Tapered reamers, otherwise known as bridge reamers, and will self centre many thanks to their sloping, tapered sides. (Reamers used in a magnet drill deserve to only me centre v the magnet turned off so the drill deserve to move to the correct position.)When ready, slightly retract the reamer so it is no in contact with the political parties of the hole and also start that spinning.Start the cut, applying steady feed push throughout the operation.Once the reamer has actually reached that widest allude the cut is complete, and the reamer have the right to be stopped and also withdrawn.

Best exercise advice:

Check the minimum torque necessity for the device in use.Apply firm, secure feed pressure throughout the cut, using the feed very slowly and also cautiously throughout the very first 1mm the cut.To maximise tool life carry out not attempt to increase the existing feet diameter past 2-3mm. If a larger, perfect hole dimension is required, then the following size reamer need to be supplied to ‘step up’ till the finished hole diameter is reached.Avoid lateral activity or tilting i m sorry can reason damage to the toolEnsure consistent application of high quality cooling lubricant, specifically when drilling special or hardened materials.Flame cut, laser cut or punched holes may not be possible to ream v an affect wrench. In this situation the hole deserve to be reamed out through a slow speed Magnet Drill through an ImpactaMag or VersaDrive reamer.Follow indict to set correct RPM speed. Untrue RPM deserve to lead to bad life or device breakage.Ensure a debris 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 use on affect wrenches and affect drivers.For considerable technical info on encourage speeds and also feeds view the end of the article.

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

There are plenty of reasons why holes should be modified after ~ they have been created – most commonly these can include specification changes, a adjust in the form of fixings to it is in used, or also simply a measure mistake in ~ some phase of the process.

Whatever the reason for enlarging a hole though, it has actually traditionally been an overwhelming to execute accurately top top site and away indigenous static, precision milling and also drilling machines, particularly in difficult materials such together steel.

The concern of "how to carry out this quickly and correctly" then came to be a actual challenge.

It to be a desire to administer a solution to these obstacles that led us to create two brand brand-new products - go into the VersaDrive and also ImpactaMag variety of construction and fabrication reamers.

VersaDrive influence Reamers


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

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

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

Technical quick guide

For more quickly performance use on impact wrenches & affect driversImpact pushed reamers space not recommended because that Flame or Plasma reduced holes. Use v a Magnet DrillReamer need to be rotating before beginning the reduced & steady feed pressure need to be used through the cutFor products thicker than 20mm use of ImpactaMag reamers is recommended


HMT ImpactaMag Reamer


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

Specially designed cut geometry allows the device to be used in an influence wrench or a Magnet drill. When provided in an affect wrench it is secured right into a distinct adapter definition the tool is easier to control, apply correct feeding rate, and also withdraw from the finished hole, enhancing tool life. This reamer will likewise fit right into a conventional Weldon magnet drill arbor.

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

The rotary/percussion influence cuts precise shavings turn off each next of the hole, approximately the widest measurement of the reamer.

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

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

When VersaDrive reamers are the finest option:

When making use of a portable strength tool prefer an affect Driver or impact Wrench and also the last hole size forced is below 26mm the VersaDrive impact Reamer would be the recommended option. This tool quickly and also easily fits the VersaDrive variety of quick-change, rapid-lock adapters and also can be provided to enlarge a feet in materials up come 20mm thick.

VersaDrive reamers can also be used with cordless drills and also magnet drills or shaft drills so because that applications requiring holes as much as 26mm diameter in materials up come 20mm thick VersaDrive reamers room still perfect because that the task.


When ImpactaMag reamers room the finest option:

If you space using a magnet drill without an adapter, require a feet size in between 26-39mm or have actually material greater than 20mm thick climate the ImpactaMag Reamer would be the recommended option.

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


Many building and also construction specialists will testify. A task on-site or in the workshop deserve to be walking fine till a little problem favor a misaligned hole, a poorly drilled hole, or a connection hole that is as well small, can put a very expensive spanner in the works.

Having a set of VersaDrive or ImpactaMag reamers top top hand means this potential difficulty can be conveniently overcome.
