Product Description:

BTA Deep Hole Drilling is a technique utilized for drilling extremely deep and precise holes in metal components, particularly when the depth exceeds the diameter of the hole. The method derives its name from the Boring and Trepanning Association.

In this process, a specialized drill tube facilitates the high-pressure coolant to pass around its exterior, reach the cutting zone, and expel the metal chips through the center of the drill. This approach ensures that the drilling operation is executed efficiently, quickly, and with great accuracy.

BTA drilling finds widespread application across industries such as oil & gas, aerospace, and hydraulic systems for the purpose of creating deep cavities in items like gun barrels, hydraulic cylinders, and machine components. It is particularly suitable for hole sizes exceeding 20 mm, wherein it is recognized for its swift operation and the ability to produce smooth, linear bores.

 

Features:

Advantages of BTA Deep Hole Drilling

  • High Efficiency – Fast drilling speed, especially for large-diameter deep holes.
  • Excellent Hole Quality – Produces straight, round holes with smooth surface finish.
  • Good Chip Removal – Chips are flushed out through the inside, reducing blockages.
  • High Precision – Better control of hole diameter and alignment.
  • Suitable for Long Holes – Can drill very deep holes (over 100x the diameter).
  • Works on Tough Materials – Handles steel, stainless steel, and alloys well.
  • Stable Process – The rigid tool setup ensures consistent results.
