    Cleaning – Tool care

    Looking after your Flowdrill

    First:

    When should I clean?

    • When there is a build-up of material on the polygon.

    Why should I clean?

    • To extend the Flowdrill’s tool life.
    • To maintain consistent and accurate hole dimensions.

    When is cleaning not possible?

    • When the drill is damaged, showing small chips in the polygon or wings.
    • When the diameter has already fallen below the allowed tolerance.

    Step to step guide:

    Step 1: Setting up equipment

    Place drill in machine and tighten. Have the machine rotating at roughly 500 rpm and then you are ready to choose your method of cleaning.

    Step 2: There are three alternative methods of cleaning

    Diamond File

    Use the diamond file to run up and down the drill removing any remnants of caked on material.

    Diamond Paste

    Apply a small amount to a solid wooden strip and then follow the same process as with the diamond file. Finally remove excess paste with a cloth.

    Emery Cloth

    This works well for larger drill sizes but can also be used for smaller sizes. Basically hold the emery cloth next to the drill and slide backwards and forwards.

    Step 3: The cleaning

    Step 1:

    Press the diamond file gently against the drill. Make sure the drill rotates counterclockwise. Work carefully along the drill, from top to bottom.

    Step 2:

    Apply the diamond paste to a wooden stick or similar tool. Then repeat the motion you used with the diamond file.

    Step 3:

    Hold the emery cloth alongside the drill and move it back and forth.

    Important information!

    Do not clean your Flowdrill too often otherwise it can cause a reduction in base material which could lead to smaller than desired hole sizes

    Please note:

    If cleaning does not restore the drill’s performance, or if visible damage is detected, the tool should be replaced. Using a worn or chipped Flowdrill can negatively affect hole quality, bush height and thread engagement. Always inspect your tool before and after cleaning to ensure optimal results.
