Designed for Reliable Deep Hole Drilling

Multi-Position Carbide Inserts

The drill head uses TPGX2807RG carbide inserts at the center, intermediate and peripheral positions. This multi-position arrangement forms part of the tool's drilling geometry, while the replaceable insert design makes routine maintenance more practical.

800-20A Guide Pads

Two 800-20A guide pads provide support and guidance during drilling. Correct guide pad selection, tool alignment and machining parameters are important for maintaining hole quality and stable drilling conditions.

Chip Evacuation and Coolant Compatibility

BTA drilling relies on a properly configured tool, drill tube and coolant system to support chip removal from the deep hole. The drill head should be matched to the machine setup, coolant supply and workpiece requirements to achieve reliable machining results.

Replacement Tooling for Existing Systems

If you are sourcing an alternative to your current BTA drill head, TALI can review the existing tool dimensions, insert arrangement, guide pad specifications and connection details. Compatibility should be confirmed against the original tool drawing and machine requirements before ordering.

Workpiece Materials and Applications

BTA deep hole drilling tools can be used for suitable metal materials, including carbon steel, alloy steel, stainless steel and cast iron, depending on the insert grade and machining conditions.

Typical applications include:

• Hydraulic cylinder components

• Mold and die components

• Industrial machinery parts

• Automotive and heavy equipment components

• Other industrial workpieces requiring deep hole drilling

For material-specific recommendations, please provide the workpiece grade, required hole depth, target hole diameter and drilling machine details.
