Plunge milling cutter
RF 100 Diver
RF 100 diver
Simply dive under all milling conditions
One tool, numerous applications: the RF 100 Diver milling cutter family is your best choice for drilling, ramping, slotting, roughing or finishing – in all materials and regardless of the milling conditions.
Extreme time savings thanks to 60° plunging angle
Thanks to its innovative geometry, the plunge milling cutter RF 100 Diver is able to plunge at a ramp angle of 60°. This steep infeed allows you to achieve time savings of up to 50 per cent when producing slotting and pockets in steel with the plunge specialist.
Plunge milling cutter
RF 100 Diver
Drilling, ramping & roughing up to 2xD
The RF 100 Diver has proven itself in applications that require a high degree of flexibility. The solid carbide milling cutter covers five operations with one tool: drilling, ramping, slotting, roughing and finishing.
Your advantages with the RF 100 Diver:
- high flexibility: one tool for five milling operations
- for all materials, especially sticky, stainless and heat-resistant materials
- 40% longer life thanks to innovative cooling of face and circumference
- special face geometry for drilling and ramping
The features in detail
Whereas drilling tools rely on axial coolant ducts and milling tools on radial coolant ducts, the RF 100 Diver milling tool offers both, providing optimum cooling and protection for both the face and peripheral geometry during drilling and plunging. Decades of expertise in carbide manufacturing at Gührig and FEM optimisation ensure maximum efficiency in cooling, chip removal and tool stability for this milling tool. As a result, the Diver performs effortlessly and efficiently even under difficult machining conditions.
Gühring has the optimal diver for every application:
3-edged milling cutter
- for weaker machines and unstable clamping conditions
- for lathes and driven tools
- especially for slotting with smaller milling cutter diameters
4-edged milling cutter short
- for more stability while slotting
- up to 25% higher feed, less deflection
4-edged milling cutter
- high-performance milling with maximum cutting speeds
- for stable machine and clamping conditions
Often copied but never equalled
The RF 100 Diver is still the only plunge milling cutter on the market that can ramp with a 60° plunging angle. This new, extremely time-saving application feature makes it the best-selling, universal plunge cutter.

More InformationRF 100 Micro Diver
This small plunge milling cutter is precisely adapted to the requirements in the micro-machining: thanks to its unequal cutting edge arrangement and an effective internal cooling, the RF 100 Micro Diver ensures cutting success in difficult-to-cut materials.
The progressive miniaturisation of parts and components requires high-performance tools even for the smallest applications. In industries such as medical and electrical engineering, but also in jewellery and watchmaking, increasingly delicate tools are being used – in materials that are increasingly difficult to machine. Gühring provides the solution: the high-performance RF 100 Micro Diver milling cutter is part of the plunge milling cutter product family, which enables an optimum plunging.
The smallest diver in the world
The RF 100 Micro Diver enables a plunging with 60° and simultaneous milling. Depending on the application, tools can be saved. The milling cutter is also characterised by its high cutting data and cutting depths. For the user, this means: more process reliability and metal removal rate, even in difficult-to-cut materials.
Micro precision milling cutter
RF 100 Micro Diver
Top performance while milling in the smallest range
From the carbide to the geometry and coating, the RF 100 Micro Diver has been perfectly tailored to the micro-machining. The micro-precision milling cutter also features the patented GühroJet cooling technology: the shank contains coolant ducts, which are arranged in a partial circle around the cutting wedge. They ensure the flow of coolant into the cutting zone – for reliable chip removal.
Your advantages with the RF 100 Micro Diver:
- for the micro-machining from Ø 0.5 – 3.175 mm
- plunging and milling with only one tool
- universal, in every application, in every material
Powerful in difficult materials
Extreme cutting data and cutting depths that were previously impossible for micro tools: only the RF 100 Micro Diver can achieve this. Our high-performance micro-precision milling cutter stands for maximum metal removal rates and process reliability for even the smallest machining operations. The plunge milling cutter is suitable for universal use, but really comes into its own when machining difficult-to-cut materials (e.g. CoCr steels).

More InformationPCD diver
The PCD Diver combines maximum cutting rates with universal application. Whether roughing or finishing, slotting into solid material or ramping with extreme immersion angles – the PCD Diver is suitable for all aluminium milling applications.
3-fluted cutter
PCD diver
A milling cutter for every ramp angle
Thanks to its innovative geometry, the PCD diver guarantees top quality with low power consumption and high stability at the same time. This means that profile and structural parts can be processed with particularly low burr – and thus save costs in the reworking.
Your advantages with the PCD diver:
- all-round talent for maximum cutting rates and endless tool lives in aluminium
- cost savings due to low-burr profile and structural part machining
- helical hole machining with reduced torque and axial force
Highest parameters with endless tool life
Fast, dynamic processes with plenty of savings potential – that’s what the PCD Diver stands for. Its cutting edge geometry reduces the torque and axial forces, enabling higher cutting speeds and feed rates per tooth. The ultra-hard PCD tool material of its cutting edges guarantees the highest tool lives.
