Control of oil flow, Centration of cutter, Slug ejection.
The EUROBOOR Pilot Pin 8 x 103mm IBC.80 is essential for the use of annular cutters. As plain as a pilot pin may look, all of these uses require high precision and extremely low tolerances – just to make sure the centre is exactly the centre, oil flow starts and stops when you need it to, and the slug does not get stuck inside the cutter. Euroboor offer a wide range of pilot pins that match the lengths, diameters and characteristics of our various annular cutters with exactly the required precision to enhance your drilling
- Precise positioning – Whilst having a perfect fit the Euroboor pilot pin is your guidance to centre the cutter.
- Oil flow regulation – In a standstill position with the cutter above the workpiece, the pilot pin prevents the oil from flowing.
- When moving down the cutter with the pilot pin onto the workpiece to commence drilling, the pilot pin is pushed up into the arbor and permits the oil to flow into the cutter for direct cooling and lubricating.
- Slug ejection – When the cutter is through the material, the pilot pin pushes the slug out of the workpiece by means of the strong spring inside the arbor. Consequently, the oil flow is automatically cut off.
