Indexable Drilling


Sumitomo WDX Indexable Drill can be used in a wide range of applications such as Counter Drilling, Surface Drilling, and Slant Face Drilling, Half Profile Drilling, OD Turning and ID Boring. They have Excellent hole accuracy, Excellent chip control, Four-cornered insert design for easy and tool management and reduce cost. Coolant-through Design Longer tool life reduces cost per part.


Features and Applications:

• Balanced Design

Cutting force during drilling is balanced between central insert and peripheral insert. The relative position of each insert is optimized to provide stable drilling.

• Excellent chip control

The chip evacuation direction can be controlled with the chip control groove at the center of the breaker, enabling good chip control.

• Versatile Tool for a variety of Maching Applications

Select among three types of breakers for different applications, allowing optimal drilling for a variety of work materials and conditions. Suitable for a wide range of applications including hole expansion, spot facing, external turning, and internal boring.

• Economical Four-Cornered Insert

This product has an extremely economical design where a single insert type can be used for the central insert or peripheral insert, with two corners for each position - a total of four corners.

There are 3 types of original chip breaker designs available that enhance chip control and lower cutting forces, applicable to low rigidity setup conditions. 
ACP300 – for steel
ACK300 – for cast iron
DL1500 – for non-ferrous material
1. Provides stable and high-quality drilling with a balanced design.
2. 3 types of chip breakers to eliminate chip control problems.
3. New coating technology achieves long tool life with improved fracture and wear resistance.
4. Economical 4-cornered insert interchangeable between the center and peripheral edges.

WDXT inserts are available in three grades:

ACP300 – for steel
ACK300 – for cast iron
DL1500 – for non-ferrous material


Also, available in 3 Chip breakers:
L – for lower feed rates
