BTA Deep Hole Drill Bit Drill Head for Drilling Deep Hole

Description: BTA Deep Hole Drill Bit Drill Head for Drilling Deep Hole Description of BTA deep hole drill:BTA deep-hole drill is a typical construction of the deep-hole drill with internal chip flow and is single-cutting drill with internal chip flow improved, with its cutting edge having staggered teeth on both sides and chips formed on both sides and discharged after entering the drill rod through channels on both sides. With uniform distribution of cutting force, the BTA deep-hole drill is featured with excellent chip division and breaking performance, stable and reliable drilling and good linearity of drilled deep holes. Advantages of BTA deep-hole drill:1. High production efficiency; feed rate: >30~180mm/min; continuous drilling without the need for retraction for chip removal;2. Stable hole diameter; holes of H9 accuracy can be stably realized in general and H8 accuracy can also be realized under good conditions;3. High hole surface roughness; it is below Ra3.2~1.6 for standard steel and Ra1.6~0.4 for nonferrous metals;4. Excellent geometric tolerance; hole roundness: <0.01mm; axis alignment: <0.4mm/1000mm (depending on hole diameter and material homogeneity)5. Among deep-hole machining tools, BTA deep-hole drill, featured with great length-diameter ratio, good stability and high efficiency, is the first choice for deep-hole drilling. ApplicationPower generation industry (turbine, boiler, etc.):Mould industry: coolant holeAuto industry: shaft, piston pin, cylinder block, etc.Aerospace industry: landing gear, gas turbine shaftSteelmaking industry: billetInjection molding machine, chemical engineering and other industries BTA stands for Boring and Trepanning Association and is also sometimes referred to as STS (single tube system) drilling. BTA drilling is a deep hole drilling process that uses a specialized drilling tool on a long drill tube to produce deep holes with a typical diameter of 20 mm [~0.80 in] and larger, and depth-to-diameter ratios of up to 400:1.BTA drilling heads are threaded and are mounted onto long drill tubes. BTA drilling heads have multiple cutting surfaces to remove chips efficiently, exhausting them using high-pressure metal-working fluid through holes in the tool head, then out the drill tube and through the machining spindle. BTA tooling is available in brazed or inserted carbide configurations.
