For a diameter-length-ratio from 15xD one generally refers to gun drilling. Gun drills are for example applied for the machining of camshafts, crankshafts,

When using FS Aluminum Gun Drilling Oil in gun drilling applications, or other metalworking applications, one can expect the following characteristics: Superior anti-welding/ wetting characteristics, dramatically improving insert, tap, and drill life Increased speed and feed rates, especially with low machine-ability materials Very low foaming, providing more efficient oil and additive

Gundrilling Advantages Building our expertise since the 1970's, Carlson has drilled practically every metal alloy in all industries. The gundrilling process offers a few key advantages including much smaller hole sizes (2.0″ down to 0.055″), more parts to production hour, tight tolerances and more.

that deep hole drilling methods dominate the whole field of drill- ing [189]. Iovkov investigated the deep hole drilling of aluminum cast.

Gundrilling is a deep hole drilling process that uses a long, thin cutting tool to produce holes in metal at high depth-to-diameter ratios. Gun drilling is effective in diameters from 1 - 50. A gundrill tool differs from a conventional twist drill by its unique head geometry; a standard gundrill has a single effective cutting edge that

Deep hole drilling RT Gun drilling operations must utilize a pilot hole or guide bushing for successful Aluminum and other non-ferrous metals.

With RT 100 Al optimal chip formation is achieved at the cutting edge in the entire material range – from tough aluminium wrought alloys to aluminium cast alloys with high silicon content. This
