New 14.00-15.99 mm Gundrills Carrying Inserts with 3 Cutting Edges
Highlights
ISCAR/UNITAC are expanding the lower diameter range of
the GD-DH gundrills family by adding drills in the diameter range
of 14.0 to 15.99 mm carrying a new TOGT 070304-DT insert featuring 3 chip splitting cutting edges.
GD-DH
Gundrills for machining centers and gundrill machines, carrying TOGT inserts that feature 3 chip splitting cutting edges and a wiper for high hole surface quality and high feed. The drills are now available in the diameter range of 14 to 28 mm and in 10, 15 and 25 drilling length to diameter ratios. Longer gundrills with up to 2400 mm length can be supplied on request.
The new
TOGT 070304-DT insert features 3 chip splitting cutting edges, a positive rake chipbreaker and a wiper for high hole surface quality. The new insert is made from IC908, a versatile PVD coated grade.
Advantages
- Deep drills with a 3 cutting edged insert (other manufacturers only offer inserts with 1 or 2
cutting edges)
- Peripherally ground highly accurate insert, providing high hole diameter accuracy of IT10
- Produces narrow chips for efficient chip evacuation, enabling higher feed rates compared to
other drills available in the market
- A wiper on the insert provides extra fine surface finish
- Direct insert mounting - no adjustment needed for accurate hole diameter
- Can carry new economical solid carbide or brazed guide pads
