Frequently Asked Questions (FAQ)

QWhat is a Tungsten Carbide Gun Drill Rod?

It is a high-precision, ultra-hard tool component engineered specifically for deep-hole drilling (L/D ratios up to 100:1+) in tough materials, offering extreme wear resistance and thermal stability.

QWhat diameters and lengths are available?

We offer standard diameters ranging from 3mm to 30mm, and lengths from 300mm to 1500mm. Customized dimensions can also be manufactured according to your requirements.

QWhich materials are these gun drill rods suitable for?

They perform exceptionally well in high-speed drilling of difficult-to-machine materials, including stainless steel, titanium, Inconel, aerospace alloys, and hardened steel.

QWhat are the advantages of carbide over high-speed steel (HSS)?

Tungsten Carbide gun drills provide up to a 10x longer tool life compared to HSS or cobalt. They allow for much higher speeds, feed rates, and maintain rigidity to prevent hole deviation.

QWhat surface treatment options do you provide?

The drill rods are manufactured with a precision-ground, mirror-polished surface finish (Ra ≤ 0.2μm). They can be provided either coated or uncoated based on application specifics.

QAre these compatible with standard gun drilling systems?

Yes, our gun drill rods are fully compatible with BTA, ejector systems, single-lip drilling machines, and modern CNC machining stations.
