MODIFY OR ENLARGE HOLES
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 tool to be used in an Impact wrench or a Magnet drill. When used in an Impact wrench it is secured into a special adapter meaning the tool is easier to control, apply correct feed rate, and withdraw from the finished hole, enhancing tool life. This reamer will also fit into a standard Weldon magnet drill arbor.
Product Benefits
- Ideal for steel erection & bridge work
- Ideal for modifying & enlarging holes
- Secured directly to the Impact Wrench
- Can be used with any standard Magnet Drill
- Available in intermediate sizes
- Unique 6 flute design for faster, smoother cut
- Prepare holes ready for installation of TCB & friction grip bolts
ImpactaMag Reamers
- Apply firm, steady feed pressure throughout the cut, applying the feed very slowly and cautiously during the first 1mm of cut.
- To maximise tool life do not attempt to increase the existing hole diameter beyond 2-3mm. If a larger, finished hole size is required, then the next size reamer should be used to ‘step up’ until the finished hole diameter is reached.
- Avoid lateral movement or tilting which can cause damage to the tool
- Ensure regular application of quality cooling lubricant, especially when drilling thick or hardened materials.
- Flame cut, laser cut or punched holes may not be possible to ream with impact wrench. In this situation the hole can be reamed out with a slow speed Magnet Drill with a ImpactaMag or VersaDrive reamer.
- Follow guidelines to set correct RPM speed. Incorrect RPM can lead to poor life or tool breakage.
- Ensure a debris free surface of sufficient steel thickness for strong magnet hold when Magnet Drilling.
- Regularly check that Magnet Drill slides, handles, arbors and movable parts have not vibrated loose over time.
Use the tables below to identify the recommended Nm of Torque or RPM for your hole size and material.
Use Nm of Torque for reaming with Impact tooling.
Use RPM for reaming with Rotary tooling.
N.B. Impact Torque recommendations are the minimum required and for most applications additional torque is a benefit. For Impact applications where Torque values available do not offer an exact match to the table below select the closest available torque setting ABOVE the recommendation.
- Identify the torque range (for the cutting tool) required using the data sheet in question 2. (Example 16mm hole in 12mm plate – Guide torque 340Nm)
- Identify the torque range on your impact wrench or impact driver
- Look up model number to see torque range
- Check if there are speed/torque settings on the tool - Example
- Select the closest torque setting on the impact wrench/impact driver ABOVE the torque recommendation
(this is for the following 2 reasons)
- Higher torque will only be used on demand
- Too low torque will lead to the tool jamming or even snapping as the flutes stop cutting and the torque transfers to the tool
