We see from your search that you're looking for information on the term "Step Drills",
and we have a large number of manufacturers' news releases and technical articles here on Manufacturingtalk which will be of interest.
Let me be your guide.
Start with
the news release Five-axis tool grinder works unmanned at night from
Koerber Schleifring UK, which we summarised at the time by saying "A 5-axis CNC tool and cutter grinder with pallet loader allows a tooling company to do 'specials' work on day shifts and 'routine' work on unmanned night shifts".
Several months prior to that,
we featured the news release Step drills produce holes for metric threads from
Kennametal UK: "Coated carbide step drills double cutting speeds while reducing cutting forces so ensure consistent repeatable holes and aid the life of the metric thread forming tools".
In August 2006, we covered the news from Koerber Schleifring UK
concerning its Walter Helitronic Power CNC tool grinder
- take a look at Wheelchanger raises CNC tool grinding output
which says: "CNC tool grinding machine has a grinding wheel changer that extends the machine's capabilities for the automated, non-stop processing of complex tool forms or large batch work".
Take a look also at the news release from Koerber Schleifring UK, Wheel changer automates CNC tool grinding,
as well as Through coolant drill removes 50% more metal from Kennametal UK,
and Straight flute drill cuts aluminium machining cost from Kennametal UK.
