Drilling tools

Drilling is a critical operation carried out late in the production cycle when the component value is already high. It can therefore make or break your productivity and profitability. Investing in drilling is an easy way to improve your bottom line. Here you can find drilling tools and solutions to help you achieve excellent hole results for a variety of machining conditions, materials and application types.

Drilling tools for composites and metal stacked materials.

Drill through a variety of carbon fibre reinforced materials (CFRP) and metal-stacked materials with ease. Whether it is aluminium, composite, titanium or stainless steel, these drills give excellent performance. 

Superior hole finish

Low-thrust geometries and high axial rake angle reduce delamination and exit burr resulting in excellent hole finish.

Ideal for drilling in aircraft frames

Fantastic tool life when drilling composite and metal-stacked materials  used in the aerospace industry for manufacturing frames, wingboxes, fuselage, stabilizers (vertical and horizontal wings at the back of an airplane), floor beams, flaps etc.
