SGIH parting and grooving blades are designed for use with GTN inserts.
The SGTBU tool block securely clamps the blades on the lathe for stable operation.

Made from high-speed steel (H.S.S.), the SGIH blades offer excellent vibration dampening properties,
making them ideal for applications requiring long overhangs in deep grooving or parting-off operations.

Width:3.0mm-4.0mm
