It has a great blend of strength and toughness. 6AL-4V / Grade 5 titanium is the most widely utilized alloy in a variety of industries.

It is not unusual to hear people say that titanium is stronger than steel. However, is it really stronger? Let us look at the table below.

Steel is one of the most commonly utilized materials in building the world's infrastructure and industries; steel can make anything from tiny ball bearings to massive skyscrapers and ships.

High speed drills are adequate for commercially pure grades with reduced hardness. However, carbide tipped drill bits are best for harder alloy grades such as 6AL-4V/Grade 5 and drilling deeper holes.

Titanium is a difficult material, hence you must use the best drill bit available. Please browse our drill selection at your convenience. Quality Tools UK exclusively sells the finest drills on the market, so you can be confident that they will last for a long time and give you premium performance.

Titanium does not conduct heat as effectively as other metals so place cutting oil to prevent overheating. Heat can easily degrade a regular drill bit so use stronger drill bit types.

Drill bits should be sharp and long enough to allow for the free flow of metal shards or chips. A dull drill impedes the passage of chips along the flutes, resulting in poor drilling results.

So what does all the data mean? It simply means titanium outperforms steel in terms of strength-to-weight ratio, as it is as strong as steel but 45 percent lighter.

Because of the unique characteristics of titanium, drilling it can be challenging. In addition, the high temperature generated during drilling and the cutting edge’s poor heat distribution makes drilling titanium alloys even more difficult.

If you look at the table, you will notice that the tensile strength of steel is actually higher than that of titanium. At first glance you will think steel is much stronger than titanium in terms of tensile strength.

Titanium tipped HSS drill bits are made to cut through difficult materials such as titanium. A titanium-tipped HSS bit reduces friction and heat, allowing for considerably simpler and faster drilling.

Steel is an iron and carbon alloy with a carbon percentage of around a maximum of 2%. Steel is further strengthened through heat treatment called tempering.

However, titanium compensates for the lower tensile strength with a lower density. In other words, titanium is a stronger metal in terms of mass per unit or weight.

You can drill titanium even with a regular HSS metal drill bit. However, drilling titanium needs extensive planning and access to the necessary equipment. Carbide tipped drill bits are recommended because they are stronger than titanium.

Carbide metal drilling bits are suited for nonferrous metal drilling. They outlive cobalt drills by a factor of ten or twenty and can easily drill through titanium. Carbide drill bits are the best bits for drilling titanium.

So when drilling titanium it’s better to use tougher drill bits like carbide because of the toughness of titanium compared to steel.

Titanium alloys are classified according to their characteristics. For example, the most commercially available titanium alloy is Grade 5, sometimes known as the workhorse grade.

The majority of premium drill bits are not designed for hand drilling. For example, titanium drilling requires high feed pressure, and a hand drill may not have enough speed to penetrate through titanium.

On the other hand, Grade23, often known as the extra-low interstitial grade or ELI, is one of the most widely used and essential titanium alloys in the medical industry. This grade is used for advanced medical and surgical procedures.

Cobalt High-Speed Steel (HSS) drill bits contain Cobalt, which boosts the hardness of the material above that of standard HSS. Cobalt increases steel's strength and significantly enhances its heat resistance.Cobalt High-Speed Steel drill bits can come with Titanium (TiN) Coating.

Drilling titanium can be more challenging than drilling other metals, due to its innate toughness. However, with the right technique, speed, and drill bit type, you can successfully drill a hole in titanium. It is quite similar to drilling stainless steel since you need moderate speed and pressure for both materials.

Carbide drill bits are the best for titanium, but in case they are not available, you can also use a titanium coated or cobalt drill bit.
