That’s 8-10 times more efficient straight away. But the kicker is you can then rotate each knife four times before replacing it. This means the knives will last up to 40 times longer than straight blade knives. Yep, you read correctly. All cutterheads come standard with solid carbide knives and replacement packets of 10 are available separately.

Although a cobalt bit can handle much harder material, a titanium drill bit offers good heat resistance and impressive durability. They are well-suited to most general-purpose drilling tasks but might not be the best option for industrial applications.

The helical-path spiral head uses 27mm-wide knives - these are almost double the standard 14-15mm knives on other segmented cutterheads, creating a finish twice as smooth, twice as quickly.

Titanium drill bits last a long time but can also drill through most surfaces; whether working with softer materials, like wood and plastic, or light metals, like aluminum and brass, a titanium drill bit can handle it. They are considered to be an excellent option for general-purpose drilling.

One of the problems our industry faces at the moment - and one of the reasons we get a lot of questions - is the variance of confusing terms that apply to cheaper machines.

That’s because these cutterheads are basically offering the opportunity to confine a series of prolonged and hidden costs into one direct payment. So ask yourself a few questions:

Thanks to their significant hardness and wear resistance, titanium drill bits have a much longer lifespan than uncoated high-speed steel drill bits. Rather than needing to replace them regularly, they can last for many years, even with daily use.

Helical vs spiral head

Well it’s about to be the same with helical-path spiral cutterheads. You only have to rotate your spiral-head knives once for every 8-10 blade changes on straight high-speed steel blades.

The extra-width means each tip passes over more of the material, leaving a smoother finish. It’s a smarter, more efficient design that not only improves cuts and machine-lifespan, but can save you a ton in replacement blades. But we’ll get to that later.

One of the questions we encounter nearly everyday is ‘What's the difference between the spiral cutterhead on this $500 thicknesser and this $1,200 thicknesser?'

But after doing some research it turns out there’s some misleading language out there, and we think it’s time someone clarified the situation once and for all…

Helical-path cutterheads have been around long enough to know that there’s no downside to any aspect of the maintenance or operation, you’ll begin saving money the minute you install them in your machine. The only drawback is that initial investment is larger than a simple carbide-tipper router bit.

When router bits transformed from high-speed steel to tungsten tipped it increased the lifespan of your average bit by about 8-10 times.

Overall, they are incredibly capable of drilling through most surfaces you would encounter with basic drilling tasks, which is why they are considered to be an all-around drill bit.

Cobalt and titanium drill bits are usually considered among the best options. While they are undoubtedly top choices, many people do not know their differences or what each type of drill bit is used for. We have created this complete guide to cobalt vs titanium drill bits to help you choose the right drill bit for your needs.

It's usually followed by 'How much longer do spiral cutterheads actually last than regular straight edge?’ They're the kind of repetitive questions we don’t mind answering, because it reminds us a little of when router bits evolved from high-speed steel to carbide tipped: honestly, the look on a few of our customer’s faces when we let them in on the worst kept secret in woodworking is pretty rewarding.

They also make smaller chips and operate with far less noise than other types of cutterheads. Unlike conventional single straight knifes, you don’t even need to replace the knife if it becomes damaged or dull. Instead, if one knife edge is damaged or needs sharpening, simply turn it to another edge in seconds.

Woodworkers buy these type of cutterheads for the quality of the cut and the removal of stress on their machine alone, but approaching the argument on a purely cost-for-cost basis, they’re an expensive proposition in one-hit.

Due to the complicated nature of designing each blade at a relative angle to each other, there is significantly higher cost in engineering and precision machining a helical pattern.

Instead of punching the material at 90°, one knife shears smoothly across the timber, before the next knife engages at the exact same angle. It’s far less work for your machine’s motor, which means true shear-cut helical spiral heads require less horsepower.

When an HSS drill bit is combined with cobalt, the result is a drill bit that is incredibly durable and impressively resistant to heat. The cobalt is added to the high-speed steel to increase the resulting drill bits' overall strength and durability. Not only does this ensure that they last longer, it means that cobalt drill bits can handle hard materials, like stainless steel surfaces, cast iron objects, and other metals and alloys that would be difficult to drill through with a softer drill bit.

While they are more expensive than a basic high-speed steel drill bit, cobalt drill bits are relatively affordable and can function as reliable, general-purpose drill bits. This explains why they are among the more popular choices for professionals and DIYers.

The cobalt content within the drill bit helps dissipate heat throughout it, so it is not concentrated in one area. This reduces the risk that the drill bit will warp or fail when exposed to high temperatures.

Consider your unique drilling needs and choose the right drill bit set for you. Investing in a good set that will last is always preferable to purchasing low-quality items you cannot rely upon when buying any type of tool.

Titanium drill bits are also composed of high-speed steel; however, the steel is not combined with another metal, which is the case with cobalt drill bits. Instead, the high-speed steel is coated with a layer of titanium nitride.

Then, when you eventually do need to replace them, they screw in evenly in a matter of seconds – no more jigs to align them with each other.

Since cobalt drill bits have high heat resistance and incredible strength, they are versatile. You can also use them to drill various surface materials, including metal, plastic, and even wood. While they are often used for drilling through hard surfaces, a cobalt bit can also handle tasks that are not quite so demanding.

Since titanium nitride is strong, it increases the overall hardness of the drill bits, as well as their heat resistance and durability. The titanium coating also changes the color of the drill bits, which is why titanium drill bits have a distinct gold color.

In case you’re wondering what we’re talking about, helical path spiral cutterheads are the new in-vogue addition to any thicknesser or jointer that’s worth the timber it planes.

Adding cobalt to the high-speed steel makes it much stronger. This means that cobalt bits can maintain their sharpness for much longer than a basic high-speed steel drill bit. Not only can they handle drilling through much harder surfaces, but cobalt drill bits also tend to last much longer than softer alternatives.

Cobalt drill bits are incredibly popular, as they offer plenty of qualities needed from a long-lasting drill bit. Typically, a cobalt drill bit is made from high-speed steel (HSS) blended with cobalt to create a high-strength alloy.

No matter how often you need to use a drill, you must use the correct type of drill bit for the task at hand. Not only is it essential to invest in high-quality drill bits to achieve accurate and efficient drilling results, but you also need to ensure that the drill bits you use can handle the material you are working with.

How inconvenient is the process of replacing the knives, reinstalling and then maintaining the cutterhead so it accurately manages the cutting edges?

The low friction coefficient of the titanium nitride coating helps reduce the buildup of heat and friction on the surface of the drill bit. This improves performance and enables titanium drill bits to drill through hard surfaces at high speeds.

You may favor a cobalt drill bit set if you need to drill hard materials or use your drill bits professionally. On the other hand, most homeowners and DIYers are more than okay with a good set of titanium drill bits.

When choosing between cobalt and titanium drill bits, your decision should be based on your drilling needs. Cobalt drill bits offer better heat resistance and are more capable of drilling through hard surfaces. In contrast, titanium drill bits are more affordable and offer impressive versatility and durability.

Helical-path spiral cutterheads are designed with a true shear cut, which means the knives are arranged in a helical spiral pattern and set at relative angles.
