Angle drilling
How to save yourself a step when drilling on sloping surfaces

Piloting has never been so easy: The new RT 100 FB flat drill is a specialist in challenging spot drilling situations and eliminates the need to face with a milling cutter. This saves you one process step and one tool when drilling on inclined or curved surfaces.

For spot drilling on flat surfaces, a drill with a 140° point angle is normally used, as this tip offers a good combination of cutting performance and stability, especially when drilling metal. But a solution that functions perfectly on flat surfaces leads to problems when spot drilling on inclined and curved surfaces: In this case, the 140° point angle means that the tool first hits the cutting edge corner on the workpiece. This one-sided radial load causes the tool to be pushed sideways and begin to vibrate. The drill then pushes further and further into the workpiece, very high bending forces are generated, which in the worst case can lead to tool breakage.

Reliable spot drilling without deflection

The RT 100 FB has a 180° point angle and a straight main cutting edge. This enables reliable spot drilling without deflection on inclined and curved surfaces up to 45°. The tool has a particularly sturdy design with a larger core and land widths. Four guide chamfers provide perfect support for the drill during spot drilling and ensure stability.

Thanks to these properties, the RT 100 FB creates perfect conditions for all subsequent tools: Precisely centred subsequent drilling with a high degree of roundness and surface quality can be produced in the pilot hole created. In addition, with the RT 100 FB, there is hardly any burr development at the hole exit, which also makes the tool ideal for cross holes.

How you benefit with the RT 100 FB:

• no need for a face milling cutter: fewer tools + fewer tool changes + shorter machine runtimes = significant cost reduction
• easy spot drilling: on inclined surfaces up to 45° and on curved surfaces
• 180° point angle for holes with flat hole base

In addition to difficult spot drilling situations, the RT 100 FB is also a popular choice when a flat drilling surface needs to be created. Even if a hole with an angled exit is required due to the component design, the flat drill is still the perfect choice. You can also use the RT 100 FB on flat surfaces, but you will then have to pre-drill with a conventional drill, as you will find in our usage tips.
