Learn how to replace and use compass lead tips for your circle cutter. Step-by-step guidance for accurate circles on wood, paper, and more.

Quick answer

To replace and use compass lead tips for a circle cutter, loosen the screw on the lead holder, remove the old tip, insert a new graphite lead, and tighten securely. Then set your radius and draw circles on materials like wood, paper, or PVC.

Why lead tips matter for circle cutting

Compass lead tips provide the pivot point for your circle cutter, anchoring the tool while the blade or pen traces the circle. A worn or loose lead tip can cause the cutter to slip, resulting in off-center or wobbly circles. Graphite tips are ideal because they mark the center clearly and slide smoothly on most surfaces.

Unlike a standard pencil, compass leads are designed to fit securely in the cutter's lead holder and can be tightened with a screw top to prevent movement. This is especially important when working on hard materials like wood or PVC, where a slipping center can ruin the workpiece.

When to replace your lead tip

Replace the lead tip when it becomes too short to secure properly, breaks, or no longer holds a sharp point. A dull or loose tip will cause the circle cutter to wander, leading to inaccurate cuts. If you notice the center point slipping or the circles are not closing properly, it's time for a new lead.

Keep spare leads on hand to avoid interruptions. The Excel Blades Compass Lead Tips for Circle Cutter come in a pack of five, providing a convenient supply for regular use.

Step-by-step: Replace and use compass lead tips

Loosen the lead holder screw: Turn the screw top counterclockwise to open the lead holder. Do not remove the screw completely; just loosen enough to slide the old lead out. Checkpoint: The screw should turn freely but remain attached to the holder.
Remove the old lead tip: Pull the worn lead tip out of the holder. If it's stuck, gently wiggle it while pulling. Avoid using pliers that could damage the holder. Checkpoint: The holder should be clear of debris before inserting a new lead.
Insert a new lead tip: Slide a new graphite lead into the holder, pointed end facing outward. Push it in until it seats firmly, then tighten the screw clockwise to secure it. Checkpoint: The lead should not move when you gently tug it.
Set the desired radius: Adjust the circle cutter's arm to the radius you need. Use the scale on the ruler or measure from the lead tip to the blade. Lock the arm in place. Checkpoint: Double-check the radius by measuring from the lead tip to the cutting edge.
Position the lead tip on the center mark: Place the lead tip exactly on the center point of your circle. Press down firmly to anchor it. Hold the cutter upright to keep the lead from slipping. Checkpoint: The lead tip should leave a small mark and not slide when you start cutting.
Cut the circle: With the lead tip anchored, rotate the cutter around the center, applying gentle pressure. Let the blade do the work; forcing it can cause the lead to slip or break. Checkpoint: Listen for a steady scratching sound; if the lead slips, reset and try again with less pressure.
