Deep Hole Boring Head

Some of Deep Hole Boring Head's key product advantages:

High precision:

The Deep Hole Boring Head enables highly accurate aperture size control, ensuring that the diameter of the hole meets strict tolerances.

They reduce the skew of the hole and maintain the straightness of the hole, which is especially important for deep holes.

Cooling and chip removal:

Designed with a special coolant channel, can directly deliver the coolant to the cutting zone, effectively take away the cutting heat, reduce tool wear, extend tool life.

The built-in chip removal mechanism can effectively remove chips from the hole, avoiding chip clogging and secondary scratching of the hole wall.

Product description

The Deep Hole Boring Head is a drilling tool specifically designed to process deep holes, usually in machining, holes with a ratio of hole depth to aperture greater than 6 are considered deep holes. The main challenges of deep hole drilling include the difficulty of heat dissipation, the difficulty of chip removal and the rigidity of the drill pipe, because the heat and chips generated during deep hole drilling need to be effectively removed, and the long drill pipe is prone to bending and vibration.

Deep Hole Boring Heads were widely selected because they were specifically designed to address these challenges and effectively complete deep hole machining tasks. Here are a few common types of Deep Hole Boring Head and their characteristics:

Gun Drill:

Gun drills usually have only one cutting edge and are suitable for machining deep holes with small apertures (2 to 20 mm) and an aspect ratio greater than 100.

The coolant enters from the center of the drill pipe and is sprayed into the cutting area through small holes in the drill bit, then discharged from the V-shaped groove with chips.

BTA Deep Hole Drill:

The BTA deep hole drill is suitable for machining deep holes with large apersizes (more than 6 mm) and a length-to-diameter ratio of less than 100.

The cutting fluid is fed through the gap between the drill pipe and the hole wall, and the chip is discharged from the drill pipe hole by pressure.

Compared to gun drilling, BTA deep hole drilling is more productive.

The choice of Deep Hole Boring Head depends on the specific machining requirements, including the depth, diameter, material of the hole, and the desired precision and surface finish.
