Can Drilled Rotors Be Turned?

When it comes to the topic of drilled rotors, questions seem to pop up like mushrooms after a heavy rain. One particular question that seems to revolve around these metal discs is whether or not they can be turned. It’s a valid inquiry and one that deserves some proper attention. So, without further ado, let’s dive into the world of drilled rotors and find out if they can undergo this mystical process known as turning.

Understanding the Basics

Before we delve deeper into the subject matter at hand, it’s crucial to grasp what drilled rotors are all about. As their name suggests, drilled rotors feature holes that are precisely bored through them. These holes aim to aid in dissipating heat and reducing brake fade during intense braking scenarios.

Now, when we talk about turning a rotor, it refers to a machining process where its surface is resurfaced by cutting away thin layers with the help of a lathe machine. Typically done to restore smoothness and parallelism, turning ensures optimal contact between the rotor and brake pads.

The Great Debate

Ah yes, here we are – at the core of our discussion: whether or not those trickily-drilled rotors can have an encounter with Mr. Lathe Machine. Brace yourselves; opinions on this matter vary wildly across gearheads worldwide!

The Nay-Sayers’ Camp

Stepping right up first are those who believe that drilling renders rotors untouchable by turning methods. They argue that drilling weakens the structural integrity of rotors by creating stress risers (small cracks) around each hole.

And guess what? They have evidence! Some automotive experts claim that performing traditional rotor turning on ones adorned with too many fancy little holes might result in catastrophic failure down the road – literally!

FAQ – Can Drilled Rotors Be Turned?

Q: Can drilled rotors be turned?

A: Yes, in most cases, drilled rotors can be turned. However, it depends on the extent of wear and damage to the rotor.

Q: What does it mean to turn a rotor?

A: Turning a rotor refers to the process of resurfacing or machining its braking surface using a lathe. It helps remove minor imperfections and restores smoothness.

Q: Is it recommended to turn drilled rotors?

A: While turning is possible for drilled rotors, it may not always be recommended. Turning can reduce the thickness of the rotor significantly, compromising its structural integrity.

Q: Are there any limitations or conditions when turning drilled rotors?

A: Yes, there are certain limitations when turning drilled rotors. If the drilling holes are too close to the minimum allowed thickness, or if they have deep cracks or significant wear, turning might not be possible.

Q: Where can I get my drilled rotors turned?

A: Automotive repair shops and brake service centers often have equipment for turning rotors. Contact your local mechanic or search for specialized service providers who offer rotor resurfacing.

Q: How much does it cost to turn a set of drilled rotors?

A: The cost of turning drilled rotors varies depending on factors like location and shop rates. On average, you can expect to pay around $20-$40 per rotor for resurfacing services.
