Gundrills and Deep Drilling Heads Carry Inserts with 3 Chip Splitting Cutting Edges in a New Diameter Range of Ø1.103-1.575”

Highlights

GD-DH
Gundrills for machining centers and gundrill machines on which gundrill tools with TOGT inserts are now available in new diameter ranges of 1.103” to 1.250”, in 10 and 20 drilling lengths to diameter ratios.

DSD-EF/IF-FT
Deep single tube drills with external 4 start / internal single thread connection carrying TOGT inserts are now available in the new diameter range of 1.103” to 1.575”. Each item in the attached catalog page represents a diameter range. For a specific head diameter, an order form should be filled out.

Based on the expansion of the exist gundrills and deep drilling heads, ISCAR/UNITAC is introducing the following new insert size:
TOGT 130408 and TOGT 140510
The new TOGT inserts feature 3 chip splitting cutting edges, a positive rake chipbreaker and a wiper for high hole surface quality. The inserts are available in 8 different sizes and made of the versatile PVD coated IC908 carbide grade.
The inserts are available with a DT and GF chipbreaker.

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 to achieve accurate hole diameter.

Gundrill Gundrills Carrying Triangular Inserts with 3 Chip Splitting Cutting Edges and a Wiper for High Hole Surface Quality Note:
• Gundrills can be supplied with up to 2400 mm length on request.
• Inserts and guide pads should be ordered separately (they are not included with the tools)
• Preventative measures:
• Do NOT operate the deep hole drill at full speed before engaging the guide hole.
• Enter the guide hole slowly at a speed of 50 - 100 rpm.
