Dezhou, China – May 7, 2026 – Dezhou Drillstar Cutting Tool Co., Ltd., a leading manufacturer of deep hole machining tools and systems based in Dezhou, Shandong Province, officially released a new series of BTA deep hole drilling tools including single‑tube drills, ejector drills and DF system drills, providing a full‑range solution for high‑precision, high‑efficiency deep hole machining in aerospace, automotive, mold, hydraulic and energy equipment industries.
As a professional enterprise focusing on gun drills, deep hole tools and CNC deep hole drilling machines, Drillstar has long been engaged in R&D, manufacturing and technical services of deep hole machining systemsDezhou Drillstar Cutting Tool Co., Ltd.. The new BTA series adopts the internal chip removal mechanism: high‑pressure cutting fluid enters the cutting zone through the gap between the drill pipe and the hole wall, and chips are discharged together with the fluid through the inner hole of the drill pipe, effectively avoiding scratches on the machined surface and ensuring stable chip flow.
Core Technical Advantages of Drillstar New BTA Deep Hole Drilling Tools
- Excellent machining quality
Internal chip removal eliminates scratch risks; circular drill pipes deliver higher torsional stiffness and bending strength than gun drills, ensuring stable machining and improved surface finish and straightness德州钻星刀具有限公司.
- High production efficiency
Larger feed rates are applicable; the ample chip removal space allows cooling‑lubrication pressure at 0.5–3 MPa, lowering requirements for sealing and oil supply systems while boosting efficiency德州钻星刀具有限公司.
- Wide application range
Suitable for both small and large bore deep hole machining; can perform drilling and reaming within certain allowances, covering Φ25 mm–Φ300 mm apertures and large depth‑to‑diameter ratio workpieces德州钻星刀具有限公司.
- Diversified product structure
Available in single‑edge and multi‑edge staggered tooth types; welded, indexable and clamp‑holder insert designs; external and internal thread connections; compatible with single‑pipe and ejector (double‑pipe) drill rods to meet diverse working conditions.
- Stable and reliable
Equipped with standard two guide pads; optimized cutting geometry and chip splitting design ensure smooth cutting, reduced tool wear and extended service life.
Drillstar’s new BTA tools are widely used in engine parts, hydraulic cylinders, machine tool spindles, mold cooling channels, petroleum pipelines and precision medical components, helping manufacturers reduce downtime, lower rejection rates and improve overall productivity.
