BORING

Tiny Tools

A family of tools designed for working in small bores. These tools are made for the high-tech, medical & small components industries. They can be used in machining centers, or with conventional machines. All tools include through-coolant, enabling the cooling fluid to reach the cutting edge efficiently.

Features:

  • Supports diameters as small as 1.0 mm (for some tools)
  • The through-coolant aids in chip removal, helping to achieve a smooth cutting action
  • Most turning applications supported (thread turning, grooving, profiling, boring, and more)
  • Variants for both right-hand and left-hand jobs available (except for MVR bars)

The following product lines can used for boring:

DTR/L BARS

A product line consisting of solid carbide bars. Their primary focus is the machining of boring applications. However, they can also handle general turning jobs. They differ from basic MTR/L bars by having a cutting edge made of superhard materials like cubic boron nitride (CBN), a man-made synthetic abrasive, or CVD thick-film diamond, which possesses the highest hardness and wear resistance of all known cutting materials.

Features:

  • Suitable for continuous or interrupted cutting
  • Minimum bore diameter: 3.1 mm / 0.12 inch
  • Both right-hand and left-hand versions available

Cutting Material(s):

The high heat resistance and exceptional toughness/hardness (albeit less than the diamond-based materials) make this material ideal for machining hardened steels (45-72 HRC). It is also well suited for machining cast materials and special alloys. It offers enhanced thermal shock resistance, and can be used at very high cutting speeds.
A diamond-based material harder than PCD, and twice as wear-resistant. CVD delivers various benefits when machining long-chipping aluminum and magnesium alloys, high-silicon aluminum, precious metal alloys, plastics with abrasive fillers, tungsten carbide, and ceramic green compacts.

MPR/L BARS

These bars were created to machine profiling and boring applications (which makes them similar to bars from the MQR/L line). On top of that, they can also be used in general turning jobs.

Carbide Grade(s):

PVD TiN coated grade for low cutting speeds. Works well with a wide range of stainless steels. (ISO P30-P50 / K25-K40)
Sub-micron grade with advanced PVD triple coating (ISO K10-K20). Extremely high heat resistance for maximum performance; Smooth cutting operation. General purpose for all materials.
Uncoated carbide grade. Optimized for non-ferrous metals, aluminum, and cast iron. (ISO K10-K30)

CBR/L BARS WITH ADVANCED CHIP BREAKER

This product line contains tools that were designed to handle profiling and boring applications. Its advanced chip breaker combined with the internal coolant bore helps to achieve efficient chip evacuation. This makes the CBR/L bars an excellent solution for machining stainless steels, super alloys, and other materials that create “curly” chips around the tool and the application.

Carbide Grade(s):

An advanced carbide grade for higher feeds and high performance, at medium to high cutting speeds. Extra-fine grain size with high hardness and toughness, combined with triple layer reddish coating; provides superior edge stability, and improved chip flow.
