  • Crafted with high-quality steel, the bar holders are coated for enhanced durability. The carbide inserts feature a tin coating, ensuring moisture and rust resistance for long-lasting performance.
  • The round shanks offer versatility, allowing operators to set both positive and negative rake angles. The chip breaker effectively eliminates long, stringy chips for cleaner cutting.
  • The carbide inserts are indexable, meaning you can simply rotate to a fresh cutting edge when one side dulls. This design eliminates the need to remove the tool from the chuck or tool post, saving time and effort.
  • Ideal for a variety of machining tasks, including turning internal holes, reaming, and copying. This set is perfect for semi-finishing existing holes and is compatible with both boring and lathe machines.

Great looking set but the foam insert was broken in shipment and the bars were all askew. This meant, yes, some inserts were chipped. Otherwise very pleased with this purchase.

Fits just fine in my boring head with no play at all. Included inserts are good and sharp. Will see how long they last, however the replacements are standard insert type so no worries there.

Nice set of good quality. The carbides allow a bigger bite, running faster without vibration and a nice finish.
