The bore cut, also known as the plunge cut, is a technique I use frequently to avoid pinching the chainsaw bar when felling small trees or bucking logs. It’s a game-changer for safety and efficiency.
What is a Bore Cut?
A bore cut involves plunging the tip of the chainsaw bar into the wood to create a notch before making the final cuts. This helps to relieve pressure and prevent the bar from getting pinched.
Step-by-Step Guide to Performing a Bore Cut
- Safety First: Ensure you’re wearing proper safety gear: helmet, eye protection, hearing protection, gloves, and chaps. Clear the area of any obstructions.
- Stance: Stand with a stable stance, feet shoulder-width apart.
- Initial Cut: Make a small notch on the side of the log where you want to start the bore cut.
- Plunging: With the chain running at full speed, carefully plunge the tip of the bar into the wood at a shallow angle. Use the bottom of the bar to control the depth.
- Creating the Notch: Once the bar is deep enough, pivot the saw to create a notch that is wide enough to allow the bar to move freely.
- Completing the Cut: Finish the cut by sawing through the remaining wood, leaving a hinge if felling a tree.
Why the Bore Cut Matters
- Prevents Pinching: Reduces the risk of the bar getting pinched, which can be dangerous and time-consuming.
- Improved Control: Gives you more control over the direction of the cut, especially when felling trees.
- Safer Felling: Allows you to create a hinge, which helps to control the direction of the fall.
Real-World Example
I was once felling a small maple tree in my backyard. Without using a bore cut, the bar got pinched, and the tree fell in an unexpected direction. Luckily, no one was hurt, but it was a valuable lesson. Now, I always use a bore cut, especially when felling trees in tight spaces.

- Start from the Base: Begin limbing from the base of the tree and work your way up. This allows you to work in a clear area and avoid tripping over branches.
- Use the Undercut Method: When removing larger branches, use the undercut method. Make a small cut on the underside of the branch, followed by a cut from the top. This prevents the branch from pinching the chainsaw bar.
- Keep the Chainsaw Close to Your Body: When limbing, keep the chainsaw close to your body and maintain a firm grip. Avoid reaching too far or overextending yourself.
- Be Aware of Spring Poles: Spring poles are branches that are bent under tension. When you cut them, they can snap back with considerable force. Be extremely careful when limbing spring poles.
- Clear the Area: As you limb, clear the area of branches to create a safe and clear workspace.
Real-World Example
I once saw a colleague get seriously injured while limbing a tree. He was rushing and didn’t properly assess the tree before starting. A spring pole snapped back and struck him in the face. This incident reinforced the importance of taking your time and using proper techniques when limbing.
Takeaway: Mastering limbing techniques is crucial for safety and efficiency. Assess the tree, use the undercut method, be aware of spring poles, and clear the area as you work.
