6 Best Rivet Removal Bits for Drilling Out Damaged Fasteners

Struggling with a snapped rivet on a metal screen door or a loose bracket on a piece of outdoor furniture can turn a simple weekend project into a frustrating standstill. Drilling out these stubborn fasteners requires the right touch and the proper bit to avoid damaging the surrounding material. Choosing the correct tool ensures that repairs stay clean, professional, and within the scope of a typical home toolkit.

DeWalt Cobalt Set: For All-Around Durability

When tackling varied household repairs, from aluminum siding to thick steel brackets, having a versatile set is essential. DeWalt cobalt bits are formulated to withstand the high heat generated during drilling, preventing the tips from dulling prematurely. This makes them a reliable choice for the homeowner who keeps a stocked workbench for occasional fixes.

Cobalt material is significantly harder than standard high-speed steel, meaning it holds an edge through multiple sessions of removing rusted or tough-alloy rivets. While the price point is higher than basic black-oxide sets, the longevity justifies the investment for those who prefer to buy a tool once rather than replacing it annually.

Storage is straightforward, as these sets usually come in compact, indexed plastic cases that tuck easily into a garage cabinet or a basement utility drawer. The bottom line: this is the “go-to” set for the homeowner who values consistency and needs a reliable bit on standby for unexpected hardware failures.

Irwin Left-Hand Bits: For Stubborn Fasteners

Sometimes, the vibration of a standard drill bit causes a rivet to spin in its hole instead of being cut away, which only deepens the frustration. Irwin left-hand drill bits are engineered to rotate counter-clockwise, which can actually help unseat a fastener that has worked itself loose. This reverse-drilling action is a clever trick for salvaging a hole that might otherwise become stripped.

These bits are particularly helpful when dealing with sensitive surfaces like delicate patio furniture or thin metal trim where you want to minimize the risk of surface marring. By gripping the rivet head during rotation, they often pull the fastener out during the drilling process.

While they require the drill to be set to reverse, the technique is simple to master after one or two practice runs on scrap material. For the homeowner dealing with older, seized fasteners, these bits offer a specialized solution that often saves the day without requiring specialized extraction tools.

Neiko Titanium Step Bit: For Precise Head Removal

If you are dealing with rivets that sit flush against a flat surface, traditional twist bits might slide off-center and scratch the surrounding finish. A titanium-coated step bit allows for a controlled approach, letting you shave the rivet head down layer by layer. This prevents the bit from “walking” or slipping off the fastener head.

The titanium nitride coating reduces friction, which keeps the bit running cool during extended use. Because step bits are designed for enlarging holes in thin sheet metal, they are perfect for cleaning up a hole after the rivet stem has been removed.

Keep in mind that these are primarily for removing the head only, rather than drilling through the entire shank. They are an excellent space-saver, as one bit effectively replaces several standard drill bit sizes in a crowded utility caddy.

Milwaukee Shockwave Bits: For Heavy-Duty Jobs

For homeowners managing larger properties, farm buildings, or heavy-duty outdoor gear, standard bits often snap under the pressure of thick, industrial-grade rivets. Milwaukee Shockwave bits are designed with a reinforced core and a specialized geometry to absorb the torque of high-powered impact drivers. They are built to handle the intense, jarring force that occurs when punching through dense materials.

These bits are ideal for projects involving thicker steel or cast-iron components where precision is secondary to raw power. The heavy-duty design makes them incredibly resistant to breakage, which is a major benefit when working in awkward positions or overhead.

While they might be overkill for light-duty tasks like mending a plastic mailbox or a thin aluminum hinge, they are the gold standard for structural repairs. If the repair involves thick metal that feels immovable, these bits provide the necessary muscle to get the job done.

ARES Rivet Removal Tool: The Purpose-Built Option

Sometimes, a dedicated tool is more effective than a generic drill bit, especially when the goal is to remove a rivet without damaging the underlying material. The ARES rivet removal tool is specifically shaped to guide the drill bit directly into the center of the rivet. This eliminates the guesswork and minimizes the likelihood of enlarging the hole unnecessarily.

This tool acts as a stabilizer, holding the bit perfectly perpendicular to the surface. It is a fantastic option for those who may not feel confident in their hand-steadiness while using a power drill.

While it is a single-purpose item that occupies more space in a toolbox than a simple drill bit, its ability to save the integrity of an expensive panel or bracket makes it a smart long-term purchase. It is the best choice for delicate, visible repairs where a mistake would be costly or unsightly.

Drill Hog M7 Bits: For The Hardest Rivet Metals

Occasionally, a rivet is made of hardened steel or a tough alloy that destroys standard bits within seconds. Drill Hog M7 cobalt bits are manufactured to an industrial grade, capable of slicing through these high-tensile materials with ease. They maintain their integrity even when subjected to the intense heat generated by drilling into hardened, rusted fasteners.

These bits are intended for the serious DIYer who does not want to compromise on performance. While they command a premium price, the ability to finish a job in five minutes instead of struggling for an hour is a clear advantage.

These bits require a steady hand and a properly set drill speed, as they are aggressive cutters. For the homeowner tired of bits “spinning” or snapping against tough metal, switching to a high-grade M7 cobalt option is a transformative upgrade.

Choosing the Right Bit Size for Your Rivet

Selecting the correct drill bit size is the difference between a clean hole and a ruined one. The goal is to match the bit size to the diameter of the rivet’s shank, not the head. If the bit is too small, the rivet won’t release; if it is too large, the hole will be irreparably oversized.

• Standard Size (1/8″): Fits most small, decorative rivets used in household crafts and thin trim.
• Medium Size (3/16″): Common for heavy-duty outdoor furniture and basic structural brackets.
• Large Size (1/4″ and up): Reserved for industrial fasteners found on vehicles or large sheds.

Always start with a slightly smaller bit if you are unsure of the size. It is much easier to carefully widen a hole than it is to fix a hole that has been drilled too large.

A Step-by-Step Guide to Drilling Out a Rivet

1. Center-Punch: Use a center punch and a light tap of a hammer to create a small indentation in the center of the rivet head; this prevents the drill bit from slipping.
2. Select Speed: Set your drill to a low speed, as high speed generates excess heat that can dull the bit and harden the surrounding metal.
3. Apply Pressure: Maintain steady, firm pressure, letting the bit do the work rather than forcing it, which preserves the life of the bit.
4. Extract: Once the head is drilled away, use a punch or a small screwdriver to tap the remaining shank through the other side of the material.

Patience is the primary requirement for this process. If the rivet begins to glow or the metal turns blue, stop immediately and allow the area to cool before continuing.

Safety First: Tips for Drilling Out Fasteners

Working with metal creates sharp, hot debris that can be dangerous if not managed properly. Always wear safety glasses to protect your eyes from flying metal shards, which are common when the head of a rivet pops off. Gloves are also recommended to protect your hands from the sharp edges of the freshly drilled hole.

Secure the object you are working on using clamps if possible. Attempting to drill a fastener while holding the object with your hand is a recipe for a slip and an injury.

Finally, be mindful of what lies behind the fastener. Always check the other side of the surface to ensure that you won’t accidentally drill into wiring, plumbing, or structural supports.

Cobalt vs. Titanium: Which Bit Material Is Best?

Cobalt bits are an alloy—a mix of steel and cobalt throughout the entire bit—which means they can be resharpened repeatedly without losing their hardness. This makes them ideal for tough, recurring jobs and long-term storage in a workshop. They are the better choice for drilling into heavy steel or stainless steel rivets.

Titanium bits, conversely, are typically high-speed steel with a thin titanium nitride coating. They excel at reducing friction and are excellent for general-purpose tasks like drilling wood or softer metals, but they lose their edge once the coating is worn away.

For the homeowner, the trade-off is clear: cobalt is for durability and harder materials, while titanium is for speed and general convenience. If you have to choose just one set for a household toolbox, a quality cobalt set will serve you better over a lifetime of home ownership.

Properly removing a damaged rivet is a skill that saves both time and money, allowing for repairs that restore functionality without the need for professional intervention. By matching the right material and technique to the specific fastener, any homeowner can achieve professional results with minimal effort. Investing in the right bits now prevents the headaches of broken tools and unfinished projects later.
