HYCHIKA Bi-Metal Hole Saw Set (17 pcs) for drilling soft metal, wood and PVC board — 19mm to 68mm, 40mm depth
Product description
What it is and what it’s for
This HYCHIKA bi-metal hole saw set is aimed at practical hole cutting across a spread of common materials: soft metal, wood, PVC board and plastic (and it also mentions gypsum board). The bundle covers a wide range of hole sizes, so you’re not constantly swapping tools when a job calls for different diameters.
On paper, it’s the kind of set you’d keep in a workshop or on a jobs-workbench for repeatable tasks like cutting recesses, making clean cable or pipe entry holes, or preparing panels before final fitting. It won’t suit every situation, but for everyday DIY and light trade use where you want options without buying a separate saw for each size, it makes sense.
One thing to keep in mind: the cutting depth is stated as 40mm, so if you often work with thicker stock, you may need to look at longer cutters or a different approach.
Key takeaways
The value here is in the combination: 11 different hole saw sizes plus the parts you need to mount and swap them. You also get a storage box, which is surprisingly important with hole saw sets—otherwise the mandrels and drill bits tend to go walkies.
In terms of performance, the blades are described as bi-metal with a cutting portion made from high-hardness material (rated between 69~81HRC) and a hard alloy steel body, with claims of wear resistance, better toughness and longer service life. The tooth design is also said to support faster cutting and cleaner, smoother results, while a side chip-removal groove is included to help discharge chips during drilling.
What you’ll notice in use
If you’ve used hole saws before, you’ll know the difference between “it cuts” and “it cuts without drama”. This set is built around efficiency and control: the improved tooth geometry is intended to raise cutting efficiency and help achieve a cleaner finish, and the chip removal groove is there so swarf doesn’t just pack into the cut.
A simple example: imagine you’re drilling a series of holes in PVC board for trunking or conduits. With multiple diameters in the same kit, you can start with the largest required opening, then step down for smaller routes—without stopping to source the next blade size. For softer materials like wood or PVC board, the bi-metal approach is commonly chosen because it can offer a more durable edge than plain steel cutters.
That said, it’s still a general-purpose set. The moment you’re dealing with very hard materials or you expect “production line” consistency, you may find more premium specialised cutters would perform better.

Pros
What stands out
- A wide diameter range (19mm up to 68mm) in one box, which is handy when plans change mid-job.
- Bi-metal blade construction is specifically designed to improve wear resistance and toughness, rather than relying on a single material.
- Chip-removal groove is included to help clear waste during cutting, which can reduce sticking and rough edges.
- Practical kit contents: blades, mandrels, drill bits, hex key, and a storage case—so you can start without hunting missing parts.
What you may want to double-check
- Cutting depth is limited to 40mm. If your material is thicker than that, you’ll need to reassess before buying.
- It’s pitched for soft metal, wood, PVC board and plastic, plus mentions gypsum board. If your projects lean heavily into very hard metals, you may find you need a more specialised solution.
- The set includes multiple drill bits and mandrels, but it’s still worth checking you’re comfortable with swapping parts and keeping them matched correctly for the job.
Who it suits (and who should look elsewhere)
It suits you if you want a one-kit solution for drilling a range of hole diameters, especially for soft materials and typical workshop installs. It’s also a sensible choice if you value organisation: the storage box plus the included mounting parts reduce faff when you’re mid-project.
It may not suit you if you frequently need deeper holes than 40mm, or if your work regularly involves harder materials where bi-metal hole saws may still be the wrong tool category. Likewise, if you only ever drill one or two specific hole sizes, buying a smaller, more focused set could be a better use of budget.
Is it worth it?
Buy the HYCHIKA bi-metal hole saw set if you’re after a practical, multi-size bundle for drilling soft metal, wood, PVC board and plastic, with a stated 40mm maximum cutting depth and a clear kit of blades plus mandrels and drill bits. The appeal is the range and the fact you get the mounting pieces and storage so you can actually use it straight away.
It’s not the best fit if your projects demand consistently deeper cuts than 40mm, or if you’re mainly tackling harder materials where you’d likely want a more specialised cutting system. In that case, you may be better off choosing a solution designed specifically for that material and depth—rather than forcing a general kit to do the job.
