LOGIQ3CHAM - Three flute exchangeable drills line designed to significantly increase productivity and reduce machining cycle time by up to 50% compared to conventional two flute drills.
ISCAR introduces a new LOGIQ3CHAM drill family which raises drilling performance levels to new heights. This family was designed by utilizing highly advanced technologies, based on ISCAR’s successful SUMOCHAM drill families.
The diameter range is 12 to 25.9 mm diameters, with drilling depth to diameter ratios of 1.5XD, 3XD and 5XD.
The new D3N drills can increase productivity by up to 50%, maintaining the excellent performance of the SUMOCHAM drills.
LOGIQ3CHAM applies the user-friendly drilling system for easy handling in accordance with the company motto of “No Setup Time”.

General Recommendations:
Dry drilling should not be performed under any circumstances
Semi-synthetic or emulsion lubricants are recommended to be used for extended tool life
It is essential to use internal coolant in all LOGIQ3CHAM applications
In cases of low coolant pressure or when used in a stationary application, adding an external
coolant can improve tool life
When only external coolant can be applied, it is recommended to drill to a maximum
depth of 2xD
An optional plug with internal thread for coolant connection can be used on stationary machines.
It can be pressed into the back-end hole of the drill

Following are the recommended ranges for coolant flow rate and pressure
for each drill diameter
Drill Diameter (mm)
For optimal performance, it is recommended to adjust runout of outer points and chisel with a
maximum of 0.02mm exceeded runout will have influence on drill performance, tool life and
hole quality.
LOGIQ3CHAM drills can be used either on milling centers or lathe machines
LOGIQ3CHAM drills can be used on sloped surfaces up to 12°. When drilling sloped surfaces of
up to 12°, reduce feed rate by 30-50% during penetration up to 5 mm depth; or use a spot
or pre-hole drill to avoid drill deviation or poor drill performance
Interrupted cut has a direct influence on hole accuracy, quality and tool life
