Boring Head Set, R8 shank, Indexable with 4 Boring Bars

Indexable Boring Tool Set with 2" Boring Head, R8 Shank & 4 Boring Bars

An indexable boring tool set is designed to efficiently remove material from holes, particularly holes larger than 0.75 inches. Carbide inserts allow for quick and easy replacement without the need to discard the entire tool. 

Boring head features a 1-1/2"-18 threaded back so you can change shanks as needed. A micrometer lead screw provides 0.001" direct reading accuracy and makes adjusting easy. 1 DIV = 0.001 which means when turning the dial by 1 division/graduation, the boring head's travel is 0.001" in radius movement and 0.002" in diameter movement. The heat treated, alloy steel shanks are held to 0.000 to -0.0005" from the nominal diameter. 

• Boring head offset is 5/8".
• Minimum boring diameter is 0.394".
• Maximum boring diameter is 5.906".
• Maximum boring depth is 1.970".
• R8 shank has a drawbar end thread of 7/16"-20.
• The cross hole is 1/2".

The included indexable boring bars come with TCMT 21.5 C6 carbide inserts for steel and alloy. The set also comes with torx & l-shape hex wrenches and a fitted carrying case.
