What Are the Different Types of Driven Boring Tool Holders?

Driven Boring Tool Holder is a cutting tool used to enlarge holes in workpieces. It usually consists of a bar with one or more tool holders and an arbor that fits into the spindle of a machine tool. The cutting edge of the boring tool is on the insert, which can be easily replaced when worn out. The holder is driven by the machine tool, which rotates the boring tool and cuts the workpiece. These tool holders come in different types based on the type of the machine tool and the application for which they are being used.

What are the different types of Driven Boring Tool Holders?

1. Hydraulic Sleeves

2. Mini Boring Bars

3. Adjustable Boring Bars

4. Twin-bit Rough Boring Tool Holders

5. Stepped Boring Bars

6. Long Boring Bars

7. Carbide Boring Bars

8. Rough Boring Tools

9. Solid Carbide Boring Bars

10. Indexable Boring Bars

Hydraulic Sleeves

Hydraulic sleeves are used to reduce tool deflection and increase accuracy. They are used to support long boring bars to avoid bending induced by the cutting forces.

Mini Boring Bars

Mini boring bars are used for small internal diameters. They are usually less than 10mm in diameter and are used for precise and small holes.

Adjustable Boring Bars

These types of tool holders can be adjusted to different sizes. They can be adjusted to suit different workpieces and can be used for reaming and boring operations.

Twin-Bit Rough Boring Tool Holders

Twin-bit rough boring tool holders are used for roughing operations. They are best suited for removing excess material from workpieces quickly.

Stepped Boring Bars

Stepped boring bars consist of different diameters in one holder. They are used to create different sized holes in one operation.

Long Boring Bars

Long boring bars are used for deep and narrow holes. The tool holders of this type can range from 3-10 times the diameter of the workpiece.

Carbide Boring Bars

Carbide boring bars are used when there is a need for high-speed cutting and long runs. They can also be used for interrupted cuts and heavy roughing operations.

Rough Boring Tools

Rough boring tools are used for heavier cuts and are intended for removing large amounts of material at high feed rates. They come in carbide or steel design.

Solid Carbide Boring Bars

Solid carbide boring bars are made from tungsten carbide and are very hard. They are used when there is a need for high-speed cutting and long runs. They are also resistant to wear and heat.

Indexable Boring Bars

Indexable boring bars have interchangeable cutting inserts, which makes them more versatile. They are suited for general-purpose turning and boring applications.

In conclusion, driven boring tool holders come in different types, and each of them has different applications. It is important to understand the different types to ensure the best one for your application.
