Material specialists
3 solutions for drilling in difficult-to-machine materials and aluminium
Here we present three new drill specialists specially designed for machining materials such as INOX, aluminium, titanium and stainless steel. With their extra smooth surfaces, they ensure reliable chip formation and removal during machining. Polished flutes and a superior surface quality in the web thinning prevent material from sticking to the cutting edges and creating built-up edges during drilling. Effective internal cooling also ensures that the temperature in the cutting zone is lowered and chips are flushed out of the hole. These tools are ideal for precise machining of a wide range of materials.

Challenges when drilling in difficult-to-cut materials
Regardless of whether they are deep holes, micro holes or regular blind holes – reliable chip removal is often a critical issue when drilling. But some materials make machining especially difficult. For example, aluminium or stainless steels create built-up edges or, in some cases, particularly long chips during machining. If these built-up edges are not prevented and the chips are not removed effectively, there is a risk of the cutting edges breaking away or the chips clogging the hole.
Added to this is the high heat build-up in stainless steels and titanium alloys. If this heat is not dissipated properly, it can lead to problems such as tool wear. These factors make machining stainless steel materials, titanium and special alloys and non-ferrous materials a complex task that requires special tools to be selected. We are introducing three new specialists with a few common features: The RT 100 T AL deep hole drill, the ExclusiveLine VA micro-precision drill and the RT 100 InoxPro solid carbide drill.
Our 3 tool highlights for drilling aluminium, titanium and stainless steel materials
ExclusiveLine micro-precision drill VA
For micro-drilling in difficult-to-cut materials
Special alloys, titanium and stainless and high-alloy steels can be easily machined with the stainless steel version of the ExclusiveLine micro-precision drill. This is made possible thanks to its newly developed flute profile with a concave main cutting edge, which promotes more aggressive cutting behaviour. In this way, it also produces easily removable short chips in long-chipping materials such as aluminium, brass or copper. As a result, drilling depths from 3xD to 15xD can be achieved with the micro-precision drill. In addition, the Perrox coating provides excellent protection against abrasive alloying constituents and prevents built-up edges, resulting in long tool lives and high feed rates.
Your advantages when machining stainless steels:
- up to twice the feed rate
- long tool life thanks to Perrox coating
- newly developed flute profile with a concave main cutting edge for aggressive cutting behaviour
| Tool | ExclusiveLine micro-precision drill VA, Ø 2.05 mm |
|---|---|
| Material | X6CrNiMoTi17-12-2 (1.4571) |
| Cutting speed | Vc = 80 m/min |
| Feed rate | fz = 0,0615 mm |
| Cutting depth | ap = 30 mm |
Solid carbide drill
RT 100 InoxPro
For high feed drilling in stainless steels
The new RT 100 InoxPro solid carbide drill has been specially designed for the production of precise holes in stainless steels and titanium materials and promises the highest cutting values and a long tool life. Thanks to its wide range of diameters from 3 to 20 mm, this drill can be used flexibly. Three versions of the tool are available: 3xD, 5xD and 7xD.
Your advantages when machining stainless steel:
- up to 50% higher feed rate in stainless steels
- maximum tool life thanks to wear-resistant Perrox coating
- optimum chip control and removal
- maximum process reliability even with deep holes up to 7xD and large diameters
| Tool | RT 100 InoxPro, Ø 3, 7xD |
|---|---|
| Material | X46Cr13 (1.4034) |
| Cutting speed | Vc = 100 m/min |
| Feed rate | f = 0,09 mm/rev |
| Cutting depth | ap = 17,5 mm |
Deep hole drill
RT 100 T AL
For deep hole drilling without material adhesion
The RT 100 T AL is Gühring’s new specialist for deep hole drilling in aluminium. This tool is used for machining a wide range of components, such as cylinder heads, hydraulic blocks and various moulded parts. The deep-hole-drill’s strengths really come to the fore in aluminium with a silicon content of less than nine percent. But the tool can also be used above this. Four guide chamfers ensure the necessary stability during deep hole drilling. Diameters range from 3 to 14 mm and when it comes to drilling depth, the customer can choose between 15xD, 20xD and 25xD versions.
Your advantages in aluminium machining:
- virtually no material adhesions
- 30% longer tool life and higher cutting data in aluminium and aluminium alloys
- high hole accuracy and very low deviation from concentricity
| Tool | RT 100 T AL, Ø 5,00 mm, 25xD |

| Material | AlSi9 (3.2573) |
| Cutting speed | Vc = 120 m/min |
| Feed rate | f = 0,25 mm/rev |
| Cutting depth | ap = 125 mm |

Precision from Gühring saves sports stars
Especially for a team’s top performers, an injury due to a broken nose or cheekbone is catastrophic. This is precisely when Malzkorn’s product comes into play: carbon fiber-reinforced face masks for elite athletes.
150 % longer tool life with the interchangeable head drill
Modular drilling systems enable quick head changes within the machine – but if process reliability is lacking, the time savings can quickly become negligible. The BT 800 demonstrates that simple handling and performance don’t have to be mutually exclusive.
What the interchangeable head drill from Gühring can do
With the BT 800, Gühring is launching a high-performance replaceable head drilling system with bayonet lock, which is particularly impressive in medium to large diameters from Ø 14 mm due to its cost-effectiveness, flexibility and tool life.
