1000mm Depth BTA Deep Hole Drill BTA Deep Hole Cutter With Steel Material

Product Description:

BTA Deep Hole Drilling is a specialized method utilized to bore extremely deep and precise holes in metal components, particularly when the hole's depth surpasses its diameter. This drilling technique is credited to the Boring and Trepanning Association.

During the process, a unique drill tube is enveloped by high-pressure coolant that circulates around its exterior, reaches the cutting region, and expels the chips (small metal fragments) through the center of the drill. This systematic approach contributes to a clean, rapid, and accurate drilling operation.

BTA drilling finds widespread application in sectors such as oil & gas, aerospace, and hydraulic systems, where the necessity to create deep cavities in items like gun barrels, hydraulic cylinders, and machine components arises. This method proves most effective for hole diameters exceeding 20 mm and is applauded for achieving high speeds and producing smooth, aligned boreholes.

Features:

✅ 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.
