Deep hole drills
The right drill for every task
The process is referred to as deep hole drilling when the diameter-length ratio is 15xD or greater. Deep hole drills are used in the machining of drive shafts, injectors, drill rods in oil production, in the medical sector, in mould making and in the food industry. Depending on the machine specifications, the hole requirements, the lot size and the hole depth, Gühring determines the most effective tool option.
Single-fluted deep hole drills
Shining in the supreme discipline
Deep hole drilling is one of the most challenging tasks in machining. However, there are several factors you need to consider to reduce the risk of tool breakage. You can find out how to use single-fluted deep hole drills correctly in the video.

ZB 80
The specialist for cast iron
The ZB 80 two-fluted deep hole drill has a brazed carbide head whose substrate and cutting edge geometry have been specially developed for machining of cast materials.
Your advantages with the ZB 80:
- total length up to 1,000 mm
- nom. Ø from 6,000 mm to 30,000 mm
- perfect for the machining of castings
Spiral deep hole drills
Spiralised chips
The highest feed rates and cutting speeds are only possible if a safe chip removal is ensured. The spiral deep hole drill RT 100 T achieves this. The video shows the solid carbide drill in action when machining a crankshaft.

More InformationProblem-free chips
The spiral deep hole drills feature a special flute geometry that ensures optimum chip removal from the hole. In order to optimally supply the cutting edge with coolant, the tools have coolant ducts with a maximum cross-section. This ensures an effective supply of coolant to the cutting edge as well as an excellent chip removal. These factors — in combination with cutting parameters perfectly matched to the application — result in chips that are easily removed even from deep holes. This effectively prevents chip jam and the associated jamming of the tool.

RT 100 T
Process-reliable drilling of up to 40xD
With the RT 100 T, the user benefits from the highest feed rates and cutting speeds, and therefore from a significant reduction in production times.
Your benefits with the RT 100 T:
- optimised flute cross-section for reliable chip transport from deep holes
- effective coolant supply thanks to maximum coolant duct cross-section
- tip coating with the Gühring A-coating (TiAlN)
HSS-E-PM deep hole drill
GT 2000
Drilling depths of up to 20xD without chip-breaking cycles
The spiral deep hole drill GT 2000 is particularly suitable for steel machining. The TiAlN-based tip coating ensures high wear resistance of the cutting edge, which is heavily loaded in the machining.
Your advantages with the GT 2000:
- up to 20xD drilling depth
- drill point with optimised S-web thinning
- parabolic flute shape with optimised surface quality ensures best chip formation
- blank flute with high surface quality for perfect chip removal
AcademyFour-fluted drills
Revolution of cast machining
Where deep holes need to be drilled in parts of the powertrain, these tools are the specialists. However, not only a large diameter range can be produced with the four-fluted drill, but also drilling depths of up to 40xD. And all this at an unbeatable speed.
