HYCHIKA 17-Piece Bi-Metal Hole Saw Set
Strengths
- Affordable price
- 17-piece total count
- Good for soft materials
Trade-offs
- Shorter lifespan
- Not for hardwood or steel
- Mandrels feel flimsy
HYCHIKA delivers a lot of pieces for the price, and while it’s not built like a pro kit, it performs decently for light to moderate jobs.

KATA 18-Piece M42 Bi-Metal Hole Saw Kit
Strengths
- Cobalt-enhanced blades
- Rust-resistant coating
- Heavy-duty case
Trade-offs
- Max 1-1/2″ depth
- Not for deep cuts
- Slight learning curve
KATA focuses on hard materials, and the M42 bi-metal with 8% cobalt is built to tackle hardwood and thin metal with confidence. The 1-1/2-inch max cutting depth isn’t the deepest, but it’s sufficient for most framing or cabinetry work. Owners report clean cuts and good tooth retention, even after repeated use in dense wood.
The heavy-duty case is a standout, well-organized and durable, making it easy to transport. With 4 drill bits and 2 mandrels, it’s well-equipped out of the box. Compared to EZARC, it sacrifices a bit of cutting speed but gains in build quality and organization. I’d pick this if you’re working with tough wood and want a kit that stays tidy on the job site.

How We Tested hole saw kits
Rather than a hands-on lab test, my research for these recommendations focused on a detailed comparison of published specifications and features across numerous kits. I weighed owner reviews from multiple sources – including major retailers and specialized forums – alongside assessments from reputable tool review sites. My experience with workshop tools and project work informed how I ranked these kits against key criteria for performance, durability, and value.
For hole saw kits, cutting capacity and the quality of the included mandrels were heavily weighted. A deeper cutting depth reduces the number of passes needed, saving time and improving accuracy. Beyond that, the quality of the bi-metal construction directly impacts the kit’s lifespan and ability to handle tougher materials without excessive wear. These factors are critical for both professionals and DIYers.
Specifications reliably indicate the range of materials a kit should handle and the sizes of holes it can cut. However, I placed significant value on owner feedback regarding real-world performance, especially concerning durability and ease of use. Reputation also played a role; established brands with a history of quality tools generally scored higher, even when specs were similar to less-known competitors. Learning proper hole saw safety tips is also essential for safe and effective use.
Choosing The Right hole saw kits
Picking the right hole saw kit can save a lot of frustration, especially if you’re tackling a project with multiple hole sizes or tougher materials.
A quality hole saw kit delivers clean, accurate cuts in a range of materials. Key considerations include the bi-metal construction for durability, a variety of sizes to match project needs, a robust mandrel system for secure attachment, and features like quick-change mechanisms and efficient chip removal to maximize productivity. Look for kits that balance material quality with practicality for your typical applications.
Bi-Metal Construction & Tooth Design
The heart of a good hole saw is the bi-metal construction. Don’t skimp here. You’ll find kits with varying percentages of cobalt in the steel; higher cobalt content generally translates to increased wear resistance, especially when cutting harder metals. While a kit boasting “high speed steel” sounds good, it’s the addition of cobalt (8% is a common sweet spot, like in the EZARC 16-Piece Bi-Metal Hole Saw Kit) that really makes a difference. Beyond the metal itself, pay attention to the tooth design. Variable tooth pitch (4/6 TPI is a good balance) is an advantage, offering faster cutting in some materials and cleaner edges in others.
Mandrel System & Size Range
A frustrating experience is constantly stopping to change hole saws. Look for a kit that uses a quick-change mandrel system, like the Snap-Lock Plus system found in some Diablo kits. This allows you to swap sizes quickly and easily without tools. Equally important is the size range included. Consider what you’ll be working on most. If you frequently need to cut holes for plumbing, ensure the kit includes the sizes you need, and check out resources on finding the correct hole saw size PVC.
- A limited kit with only a few common sizes might be sufficient for simple tasks.
- A larger kit with a wide range of sizes (like the Milwaukee 28-Piece Ice Hardened Kit) offers greater versatility but can be overkill if you only need a few specific sizes.
- Consider whether the mandrel is universal (fitting multiple hole saw diameters) or if you’ll need separate mandrels for different size ranges, as this impacts convenience and storage.
Value & Practicality
While top-of-the-line kits can be tempting, a balance between price and performance is crucial. Don’t assume the most expensive kit is always the best choice for your needs. The HYCHIKA 17-Piece Bi-Metal Hole Saw Set, for example, offers a surprising amount of value for a budget-friendly price point.
A good rule of thumb: if you’re primarily cutting soft materials like drywall or wood, you can get away with a less expensive kit. But if you anticipate frequently working with metal, invest in a higher-quality bi-metal kit with a significant cobalt content.

Frequently Asked Questions
What’s the difference between a hole saw and a spade bit?
A hole saw cuts a circular opening, while a spade bit drills a hole with a flat bottom. Hole saws are designed for cleaner cuts in various materials and larger diameters, whereas spade bits excel at quickly drilling through wood.
Are all hole saw kits compatible with cordless drills?
Most are, but higher-voltage drills (18V or 20V max) perform better, especially with larger hole saws or tougher materials. A drill with a high auxiliary handle position helps maintain control.
How can I extend the life of my hole saw blades?
Using a cutting lubricant (like oil or wax) reduces friction and heat buildup, preventing premature wear. Also, avoid applying excessive pressure, and let the saw do the work at a consistent speed.
What should I look for in a hole saw kit if I frequently cut metal?
Prioritize a kit with a high cobalt content (8% or greater) in the bi-metal construction and consider hole saws for metal cutting. Variable tooth pitch is also beneficial for cleaner cuts.
What’s the best way to prevent a hole saw from ‘walking’ when starting a cut?
Using a center punch to create a dimple before starting will help guide the pilot bit. You can also start at a very slow speed and apply gentle, consistent pressure.
The Bottom Line
Choosing a hole saw kit often comes down to balancing how much you want to spend against how often and what materials you’ll be cutting. For most homeowners and DIYers, the Diablo Bi-Metal Hole Saw Set offers a solid combination of quality, durability, and a reasonable price. It’s a kit that will reliably handle a wide range of projects without breaking the bank.
If you’re on a tighter budget, or anticipate primarily working with softer materials, the HYCHIKA 17-Piece Bi-Metal Set delivers impressive value. For those needing maximum versatility and tackling tough metal work regularly, the Milwaukee 28-Piece Ice Hardened Kit is the way to go, though it represents a significant investment. Remember, keeping your tools in top shape is vital, explore hole saw sharpening methods to extend their lifespan.
Ultimately, the specifications matter less than understanding your typical tasks. Prioritize a kit with good bi-metal construction, a secure mandrel system, and the sizes you’ll actually use. Don’t chase the biggest kit or the highest cobalt percentage if your needs are modest; focus on getting a reliable tool that fits your projects and skill level.
