Tube & Sheet Drills

Karnasch Tube & Sheet Drills for Sheet Metal Drilling

Tube and sheet drills are similar to step drills but do not have steps, instead they are a smooth conical shape and can be used for drilling incremental diameters by plunging to the correct depth (e,g, 6.1mm, 6.3mm, 8.4mm).

Karnasch tube and sheet drills are CBN ground with a spiral flute and split point.  The HSS-XE substrate and TiN coating gives fantastic tool life, especially on stainless steel or tougher steels. Karnasch step drills are available for drlling from 5mm to 40mm diameter.  Buy today for next day delivery.
