Iscar 2300720 Sgtbk Indexable Blade Tool Block

Product Description

The ISCAR 2300720 is an indexable cutoff blade tool block built to SGTBK style specifications for use in grooving, parting, and turning operations on CNC lathes and turning centers. The block accepts blades with a compatible height of 52.6 mm (2.071 inches) and a compatible blade width of 8.5 mm. Overall length measures 135 mm (5.315 inches), overall height is 90 mm (3.543 inches), and overall width is 60 mm (2.362 inches). The reversible design extends tooling life and reduces downtime by allowing the block to be flipped when one side wears.

This tool block is suited for production turning environments where repeatable, rigid blade positioning is required during grooving and parting cycles. The SGTBK style is commonly used on medium to large-bore turning centers where shank dimensions must match the machine turret pocket precisely. The 38 mm shank height (1.496 inches) and 35 mm shank width (1.378 inches) define the mounting envelope. Machinists and tooling technicians working in job shops, production facilities, and contract machining operations are the typical end users.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine fully powered down and in an e-stop or lockout-tagout state before any tooling change. Verify that the turret pocket dimensions match the 38 mm shank height and 35 mm shank width before seating the block. Confirm blade seating and clamping torque per the machine tool manufacturer's guidelines before resuming cutting operations. Do not operate without the indexable blade fully secured in the block.
