Customer Review: They work pretty good better quality than what they were yrs ago when they first came out a lot of bang for the buck in this set
Customer Review: This set worked well for an automotive project where I needed to cut out spot welds. I used a drill bit to make a pilot hole first, and the cutters went through sheet metal easily. I did break a couple of the hole saw-style bits, but the kit includes extras, so I was still able to finish the job without issue.I also tried the end mill-style bit and honestly liked it even better than the hole saws — it worked great.This set is perfect for one or two projects.

Customer Reviews
Customer Review: This is a well thought out product for clearing spot welds, a task that is common in the auto restoration community and auto body shops. The drill bits have a flat section to ensure solid connection in a drill chuck. The set comes with plenty of spare parts as well.A few weeks back before I got this, I had to clear some plug welds. Thinking back to that, I believe this product can work on plug welds in thicker steel like what I had to deal with a few weeks ago. I did a test hole in thicker steel (1/8″), which is thicker than your typical 18-20 gauge rocker panel and it went through with ease.The absolute best part of this set is the spring loaded guide. Typically it’s difficult to maintain a fixed spot with your typical drill bit because it walks in the uneven surface that a spot weld makes. Even after you hit a spot with a punch, it tends to walk. With this cutter, you use a punch to set your center, and the spring loaded pointed guide will stay in that center spot while the cutter removes the weld between the two pieces of steel. Because of this, I will be using this cutter in situations beyond simply clearing existing spot welds. Plenty of times I find myself needing to drill into less than virgin steel without the benefit of a press or other guide to hold the bit from walking. This tapered guide handles that and the cutters in this set are typical sizes for hole for any number of uses.All and all, for a niche product, this has some uses beyond the simply clearing spot welds.
Customer Review: This is a review for the Thinktool 18 PCS Spot Weld Cutter Sets Double Sided, 3/8″ and 5/16″ HSS Spot Weld Cutter Remover Drill Bits with Hex Shank, Titanium Coated Cobalt Spot Weld Drill Bit Set Kit 6.5MM 8MM 10MM. This Thinktool spot weld cutter set is a solid choice if you want to remove factory welds without destroying surrounding sheet metal. The 3/8″ and 5/16″ sizes covered most of my automotive body work, and the double‑sided HSS cutters give you more life before you have to replace a bit. The hex shank griped well in my drill and doesn’t slip like smooth shanks sometimes do. With the proper lube (not included but you can get that lube right here on Amazon) and moderate pressure, it produces clean circles and leaves the underlying panel largely intact, which saves a lot of grinding and patching later. It’s not a miracle tool, if you lean on it too hard you can still dull or pssibly chip the teeth, but for the price and versatility, I found it to be a very handy kit to keep in a body or restoration toolbox. Many uses for any spost weld removal, however, and my lawn mower for the spring could use this for me to reweld up. Comes in a little carry case. I like it very much.

Customer Reviews
Customer Review: These work great. Slow and steady, I drilled probably ten welds before one tooth broke and I had to flip the cutting bit. Initially drilled small pilot holes to guide the bit, but a couple taps of a center punch was enough. Once it bites and makes a small ring, it will stay steady. I went a little deep on one spot, but most of them came out flush. Drill a bit, try to pry, rinse and repeat until the top panel pops off, then just grind the nubs.
Customer Review: I was actually a bit shocked by these. I don’t usually deal with a lot of spot welds and in the past I’ve just ground down the 1 or 2 needed for the task at hand. However, I decided to do the rockers on my plow truck and figured for $30 bucks i’d give it a shot. Wow…just wow. 50-60 spot welds with a single bit–I was shocked. Best 30 bucks I’ve spent in a while. 30-45 minutes to knock out 50+ spot welds was actually pretty impressive and certainly better than grinding them down for hours.
7. 3-Piece Spot Weld Drill Bit Set, Titanium Coated Cobalt Steel for Welding Removal, 1/4″, 5/16″, 3/8″ Sizes
This 3-piece set provides three common sizes (1/4″, 5/16″, 3/8″) in one affordable package.

- Easy to spot in the toolbox
Cons:
- May dull quickly without cutting oil
- Not as durable as pure M42 cobalt bits
- Some users report walking on uneven surfaces
Customer Reviews
Customer Review: These are pretty OK for drilling spot welds, but if you don’t use oil on every single weld that you’re broaching, these things will go dull quick. I’m gentle with my hand tools. I don’t just drive on in there and destroy the bit on the first spot weld that I’m trying to cut, but I was surprised that this thing still went dull even when using a heavy thread cutting oil as a lubricant.
Customer Review: I like these better than the core drill / hole saw style of cutters. These make a clean break if you get them centered properly on the weld. They only leave a small divot in the remaining panel, and little or no grinding is needed to clean up the area. They seem to last pretty well if you use a bit of cutting oil and don’t run them too fast.
10. RENYU 5-Piece Cobalt Spot Weld Drill Bit Set, Titanium Coated for Welding Removal, 5/16-inch (8mm) in Black

Complete Buying Guide for Spot Weld Drill Bit
Essential Factors We Consider
When choosing a spot weld drill bit, the material is paramount—cobalt steel (M42 or M35) offers superior heat resistance and edge retention, while titanium-coated HSS provides a budget-friendly upgrade. The shank type matters too: hex shanks prevent slippage in drill chucks, especially with cordless drills. Size compatibility is critical—measure your spot welds; common diameters are 5/16″ (8mm) and 3/8″ (10mm). A spring-loaded guide, like on our #5 pick, eliminates walking on uneven surfaces. Also consider sets with multiple sizes or replacement blades for versatility. For professional use, invest in bits with industrial coatings like TiAlN for extended life.
Budget Planning
Spot weld drill bits range from $15 for basic sets to over $60 for premium cobalt sets. For occasional DIY, a $20-30 generic set suffices, but expect shorter bit life. Frequent users should budget $50-100 for cobalt-titanium sets like our top picks—they last longer and save money per hole. Factor in replacement costs: some sets include spares, which adds value. Remember to budget for cutting oil ($5-10) to maximize bit lifespan, regardless of price point.
Final Thoughts
Spot weld drill bits are specialized tools that transform panel removal from a grinding nightmare into a clean, efficient process. The right bit depends on your usage frequency, material types, and weld sizes. Don’t skimp on quality if you do this regularly—the time and material savings justify the investment. Always use moderate drill speeds, apply cutting oil, and start with a center punch for accuracy. With proper care, even mid-range bits can last through many projects, making them a worthy addition to any automotive toolkit.
Frequently Asked Questions
Q: What size spot weld drill bit do I need?
A: Most automotive spot welds are 5/16″ (8mm) or 3/8″ (10mm). Check your vehicle’s specifications or measure existing welds. A set with multiple sizes offers versatility for different applications.
Q: How do I prevent the drill bit from walking on the weld?
A: Use a center punch to create a starting indentation, or choose bits with a spring-loaded guide like our #5 pick. Applying steady pressure and using cutting oil also helps maintain alignment.
Q: Can I use spot weld drill bits on aluminum?
A: Yes, but aluminum requires slower speeds and plenty of lubricant to prevent clogging. Cobalt and titanium-coated bits work well, but dedicated aluminum bits may yield better results.
Q: How often should I replace spot weld drill bits?
A: Replace when cutting becomes slow, produces excessive heat, or leaves ragged edges. With proper use and lubrication, quality bits can last through dozens of welds. Lower-cost bits may need replacement after just a few uses.
Q: Are hex shank bits better than round shank?
A: Hex shanks provide better grip in drill chucks, reducing slippage during high-torque operations. They’re especially useful in cordless drills with keyless chucks. Round shanks are more common but may slip under heavy load.
Choosing the best spot weld drill bit depends on your specific needs—durability for professional use, value for occasional projects, or versatility for multiple sizes.
