Review: Excellent set of METRIC bits! - At the time I purchased these, I only intended to use them for light duty (drilling into polymer). However, as fate would have it, I had to use them to drill into hardened steel, and much to my surprise, they performed admirably. It was a pleasant surprise (I was expecting "Chinese junk") and I'm very happy with this purchase; especially considering that it's a METRIC set, which is difficult to find (in the USA). I wish the set had a 1mm bit, but oh well. It's just a preference, not anything against the quality of the bits in this set. ============= Update 1/16/18 ============= My rating has changed from 5 stars down to 3. I needed to drill into metal again--actually I wasn't even drilling new holes, but just "chasing" already existing holes to expand them--and neither the 4.5mm or 4.8mm bits would do anything. They just spun around getting hot, without cutting anything. I even tried the 5mm bit, even though that was too big for my purposes, and it also did nothing but spin. Thus, I've used four of the bits (4, 4.5, 4.8, and 5mm), and only one of them did anything. The one that actually worked did its job well; the others are a HUGE disappointment. ============= Update 1/25/18 ============= Kudos to Migiwata customer service (thank you, Bella!). After hearing about my not-so-pleasant experience with these bits, they sent me a second set. Apparently their original supplier had run dry, and they had to use a second, temporary supplier while the original caught up with demand. The first set that I received was from the temporary supplier. The new set is from the original supplier, and the bits seem to be in order in this new set. So how do you tell the difference? By the case (see photos). The set with the blue dot on the case--which is a plastic retainer to keep the case closed--is from the original supplier. Now if you happen to get a set without the blue dot, don't panic. Just because I got a subpar set that slipped through the manufacturer's quality control process doesn't mean that you did, too. Try the bits out first. WORST case is that Migiwata customer service takes care of you like they did me; best case is you don't even have a problem. As for me and my review of this product, I'm a happy camper again and am bumping my rating back up to 5 stars. The bits are great (make sure to use a good cutting lubricant/coolant) and Migiwata customer service is stellar.
Review: Best wheel stud bit - Excellent. Had to drill out a wheel stud. Worked incredibly well.

## Features

- TRUE M35 GRADE COBALT STEEL: Manufactured from premium High-Speed Steel containing 5% Cobalt (HSS-Co), these bits are heat-hardened to cut through tough abrasive materials. They offer significantly higher heat resistance and wear durability compared to standard HSS bits, making them the ultimate choice for drilling into stainless steel, cast iron, and titanium alloys.
- PRECISION 135° SPLIT POINT: Equipped with a 135-degree self-centering split point, these bits bite into the material immediately upon contact. This active cutting tip prevents "walking" or wandering across the work surface and eliminates the need for a pre-punch pilot hole, ensuring accurate and clean starts every time.
- FULLY GROUND & EFFICIENT: Unlike roll-forged alternatives, our bits are fully ground for precise dimension accuracy and concentricity. The precision-engineered dual twist flute design ensures rapid chip removal, effectively reducing friction and heat buildup for a smoother, cooler drilling process.
- 15PC METRIC SIZE COVERAGE: This comprehensive metric set includes 15 essential sizes: 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 8, 9, and 10mm. It is a versatile kit suitable for a wide range of projects in metalworking, automotive repair, and general DIY on wood, plastic, aluminum, and hard metals.
- HEAVY-DUTY INDEXED CASE: The bits are housed in a rugged, impact-resistant ABS plastic case with rubberized corners for extra protection. The case features a folding design with clearly marked size indexes (raised lettering) for easy identification, keeping your tools organized, secure, and ready for transport to any job site.

## Questions & Answers

**Q: Can these drill bits cut through hardened steel or stainless steel?**
A: Yes. M35 grade steel with 5% Cobalt is specifically engineered for high-tensile metals like stainless steel, cast iron, and titanium alloys. For fully hardened steel (HRC > 50), carbide bits are recommended.

**Q: Will these bits fit my standard cordless drill?**
A: Yes. These feature standard round straight shanks. The largest diameter is 10mm, allowing them to fit securely into any standard 3/8-inch (10mm) or 1/2-inch (13mm) drill chuck.

**Q: Do I need to use cutting oil or lubricant?**
A: Highly recommended. While Cobalt is heat-resistant, using cutting fluid significantly reduces friction and heat buildup. This prevents the bit from annealing (softening) and greatly extends its lifespan.

**Q: Do these bits require a center punch to start?**
A: No. These bits feature a 135° Split Point tip. This design is self-centering and cuts immediately upon contact with the metal, preventing the bit from "walking" or skating across the surface.

**Q: Are these bits just coated with Cobalt or solid?**
A: They are solid M35 Cobalt steel throughout, not just coated. Unlike titanium-coated bits that lose effectiveness once sharpened, these maintain their heat resistance and performance even after resharpening.

### ⭐⭐⭐⭐⭐ Best wheel stud bit
*by R***H on December 23, 2025*

Excellent. Had to drill out a wheel stud. Worked incredibly well.

### ⭐⭐⭐⭐ Decent budget bits, poorly made case.
*by D***. on September 1, 2025*

The bits themselves are OK, but definitely not on the higher end (also much lower price than high end bits). The case is poorly molded and low quality. Next time, I'd likely elect to buy a more expensive set.
