View profile →WIDMA, the machine tool division of Kennametal India, is a deep hole drilling machine manufacturer in India offering gundrilling, BTA drilling, counter boring, skiving and roller burnishing machines with drilling depths up to 3,000 mm.
View profile →Gun drilling uses a single-lip drill with external chip evacuation and pressurized coolant, typically for bores from about 0.5 to 50 mm. BTA drilling removes chips internally through a tube and suits larger diameters and greater depths.
Gun drilling machines process most engineering materials — carbon and alloy steels, stainless steel, cast iron, aluminum, titanium and nickel alloys — as long as cutting parameters and coolant pressure are matched to the material.
Production gun drilling routinely achieves 50:1 to 100:1 depth-to-diameter ratios, and with pilot holes and extended tooling considerably deeper ratios are possible.
