    Frequently asked questions about Before buying

    This highly depends on the carefulness of the operator when inspecting where to conduct drillings. You want to avoid any nails or metal plates in any wood products as much as possible to preserve the bit. You will also need to be careful and aware of what type of substance the needle will exit through whether it’s sand, soil, granite or etc.

    With the IML-RESI PD-series, you can perform approx. 200 measurements per battery charge (battery: 18 V, 5.0 Ah). With the IML-RESI F series, you can perform approx. 50 measurements per battery charge (battery: 18 V, 4.0 Ah).

    The drills are approximately 5-7 kg depending on the size of the drill. We always recommend anyone purchasing a drill to opt-in for the handle and stability strap. When you are conducting inspections on an all-day basis it’s safer, secure and ergonomic to have the drill strapped to you to reduce any damages that may incur.

    One of the best features of our drills, especially for arborists working in the field of inspecting live trees, is the fill-in methods of the bits. Our bits are 3mm and while they are already small in size, when the needle retracts it pulls the wood back in to fill the hole. Immediately after you would not be able to stick the bit fully back in the hole that was drilled. As time goes on the tree seals the hole.

    Yes, the drill can inspect when it is in freezing weather. However, decay can also freeze and show a higher resistance than above freezing. However, you can still detect decay with the change in the resistance if the decay is frozen.

    The standard inspection drills are water resistant, not waterproof. You will want to treat the drill as you would your smart phone of other electronic devices that are water resistant.

    The wood inspection software can provide automatic results for pole inspections and detailed measurement activity for wood products. These can be uploaded to three different devices per license.

    Yes, we conduct a first short training via telephone or video call after you have bought a drill. You can also attend to one of our seminars. You can find more information at IML Seminars.

    Our wood inspection drills are commonly used as a reinforcement for the VTA for tree inspections. The resistance drill is a favorite for arborists and tree specialists because it provides data on the internal state of the wood. A tree specialist is able to show measurements backing up their conclusion to save or remove a tree using the data collected from the resistance drills. They get this by drilling into any area of the tree including the trunk, branches or roots.

    Many customers use the drill for pole inspections by conducting three drillings on the pole. First to determine the diameter for the WoodInspector software, second drilling into the base of the pole at an angle of about 30 degrees and then another drilling perpendicular to this at the base of the pole. This way the inspections are calculating the data below ground where there is a higher chance of decay. The WoodInspector software provides instant results of the drilling by determining if the pole is a pass, marginal or fail.

    With the WoodInspector- software you will get a direct condition assessment of the wooden pole right after performing the measurements. Here, individually specified rot and cavity limit values of the timber branch to be inspected are included as criteria for the evaluation. To view more details visit the WoodInspector page.

    The PD- and F-Series are available in different versions. The MD-Series is only available in one drilling depth.

    • IML-RESI PowerDrill-Series: 200mm – 1000mm
    • IML-RESI F-Series: 300mm – 500mm
    • IML-RESI MD-Series: 300m

    The wood inspection drill measures the force of the needle turning through the wood product. For example, when the bit hits any soft decay the force on the graph will drop and if the needle hits a hard, brittle decay the graph will spike. If the bit runs through a cavity area the graph will drop measuring no resistance for the bit. The measurements are then collected on either a wax paper strip (F-Series) or electronically recorded for an instant upload (PD-Series).

    With the F-Series drill the measurements are recorded on a wax paper strip. Typically users scan the wax paper strip into their report reinforcing their assessment of the wood. The PD-Series drill records the measurements automatically in digital form and can instantly upload these results to your computer via Bluetooth or USB cable. Software is available for your computer to analyze and organize your collected results.

    All additional modules can also be retrofitted to your device. Either at our service centre or conveniently at your home with an activation code generated by us.

    Press the device against the object to be tested. When the safety button is pressed, press the red and black button simultaneously. The tilt indicator in the display now lights up green and the REL symbol appears in the upper right corner. The current unit orientation has thus been selected as reference plane 0°. To switch off the real time mode, return the unit to its original position and press the safety switch and the two buttons again, or switch the unit off and on again.


    Press the red button for a long time > Tilt compensation: ON

    Now the tilt compensation is switched on. If the drilling depth preselection is switched on, the machine will select the actual drilling depth according to the set diameter/radius and the current tilt angle. ! The TLT add-on module is required for this!

    It is possible to choose between several drilling needle speeds in the Advanced View, equal to the feed rate

    System Controls > Drilling Needle Speed > Mode: Advanced

    The different steps can also be individually assigned different speeds.

    4 reviews for IML-RESI PowerDrill ®

    1. Clayton

      PD- series has totally superseded the F-Series (400S) with significant improvement particularly the additional ‘Feed’ curve added another opinion for the arborist to counter-check the shaft friction encountered in the ‘Drill’ curve.

    2. David chua

      Great products

    3. Dexter

      Very accurate detection of internal decay of tree trunks,easy to operate,I use the PD 400 to check the health of street trees.

    4. Andy

      In addition to the drill curve, the Feed curve is more useful,some special cases can be judged by this curve.
