Threaded Anvil Points for the Foredom AK101: When to Replace Them

Quick answer

Replace a threaded anvil point on your Foredom AK101 as soon as you notice a flattened tip, inconsistent hammer marks, or a loose thread fit. Swap in a new point using the included wrench pin, and always match the point shape to the texture or setting task at hand.

Signs that the anvil point needs replacing

Anvil points wear gradually, so the first clue is often a change in the quality of your hammer marks rather than a dramatic failure. Inspect the tip under good light before each session. A point that has lost its crisp edge or has developed a flat spot will transfer a duller, less controlled impression to the metal.

Also check the thread engagement. If the point feels loose or wobbles when seated, the threads may be worn or damaged. Continuing to use a loose point can damage the handpiece's internal threads, turning a cheap replacement into an expensive repair.

• Flattened or rounded tip that no longer produces a distinct mark
• Inconsistent hammer strikes or a tendency to skate across the surface
• Visible thread wear or a point that will not tighten securely
• A change in the sound or feel of the hammer action during use

Choosing the right replacement shape

The Foredom AK101 set includes six distinct point shapes, each suited to different tasks. The ball nose creates soft, dimpled textures; the fine point is ideal for detailed stippling; the square and rectangle points produce broader, more geometric impressions; the cylinder is useful for planishing or flattening; and the bezel rocker is designed for setting stones. If you are unsure which shape you need, start with the fine point for detail work or the ball nose for general texturing.

Because these points are sold individually, you can replace only the shape that wears out most often. If you frequently use the fine point for stippling, keep a spare on hand so you are not caught mid-project.

When to replace versus when to re-polish

A lightly worn point can sometimes be restored by careful polishing on a fine abrasive wheel, but this removes material and shortens the point's life. For most users, replacement is more reliable once the tip has lost its original geometry. Polishing is best reserved for removing a small burr or a single nick, not for reshaping a worn point.

If the point has been dropped or the tip is chipped, do not attempt to grind it back into shape unless you have a lathe and the skill to maintain the exact profile. A distorted point will produce unpredictable marks and may damage your work.

Step-by-step anvil point replacement

1. Disconnect the handpiece: Turn off the flex shaft motor and unplug it before starting. Remove the handpiece from the shaft if necessary for easier access. Never work on a connected handpiece; accidental starts can cause injury.
2. Remove the old point: Insert the wrench pin into the hole on the side of the anvil point and turn counterclockwise to unscrew it. If the point is tight, apply steady pressure rather than forcing it. A sudden slip can damage the threads; keep the pin fully engaged.
3. Clean the threads: Use a soft brush or compressed air to remove any metal dust or debris from the handpiece's threaded socket and from the new point's threads. Debris in the threads prevents the point from seating fully and can cause wobble.
4. Install the new point: Thread the new point into the socket by hand until it is snug, then use the wrench pin to tighten it gently. Do not overtighten; the point should be secure but not forced. Overtightening can strip the threads or make future removal difficult.
5. Test the action: Reconnect the handpiece and run the motor at a low speed. Listen for unusual noise and check that the point strikes evenly on a scrap piece of metal. If the point wobbles or the hammer action feels irregular, stop and recheck the seating.
