DEZHOU, China – June 1, 2026 – Dezhou Drillstar Cutting Tool Co., Ltd. (“Drillstar”), a leading Chinese manufacturer of deep hole machining solutions, officially launches its upgraded BTA (Boring and Trepanning Association) deep hole tool series, delivering unrivaled precision, efficiency, and durability for large-diameter, high-depth hole applications across aerospace, energy, automotive, and heavy machinery industries.
Engineering Excellence: Core Advantages of Drillstar BTA Tools
Drillstar’s BTA system adopts a high-pressure internal chip removal design (single-tube STS & double-tube DTS), the gold standard for deep hole drilling with length-to-diameter ratios exceeding 100. High-pressure coolant (5–30 MPa) flows through the gap between the drill tube and workpiece wall to the cutting zone, cooling and lubricating the tool while flushing chips backward through the hollow drill rod—eliminating chip jams and surface scratches for superior hole quality.
Key technical strengths include:
- Ultra-High Precision: Achieves IT7–IT11 dimensional accuracy, straightness ≤0.3 mm/m, and exceptional cylindricity, meeting stringent aerospace and mold-making requirements.
- Premium Material & Coating: Crafted from Swiss Istech cemented carbide with Balzers nano-coatings, delivering extreme wear resistance and thermal stability for hard-to-machine materials (titanium, Inconel, stainless steel).
- Wide Diameter Coverage: Standard BTA drills range from 25 mm to 300 mm in diameter, with custom non-standard sizes available for unique project needs.
- Vibration-Dampening Design: Optimized guide pads and multi-edge geometry reduce chatter, ensuring stable, continuous cutting even at high feed rates.
Versatile Applications Across Industries
Drillstar BTA tools solve critical deep hole machining challenges for diverse sectors:
- Aerospace: Engine cylinder blocks, landing gear components, and turbine shaft holes.
- Energy: Oil/gas exploration equipment, nuclear power plant parts, and hydraulic system components.
- Automotive: Transmission shafts, crankshafts, and high-precision hydraulic valve bodies.
- Heavy Machinery: Large spindle holes, mold deep cavities, and shipbuilding structural components.
Commitment to Innovation & Customization
As a technology-driven enterprise, Drillstar integrates R&D, production, and technical support to provide turnkey deep hole machining solutions—from BTA drills and drill tubes to CNC deep hole drilling machines. The company holds ISO 9001 certification and adheres to strict quality control, ensuring every BTA tool meets global manufacturing standards.
“Our upgraded BTA series represents Drillstar’s dedication to pushing the boundaries of deep hole machining,” said a company spokesperson. “We aim to empower manufacturers worldwide to achieve higher efficiency, lower costs, and consistent quality in their most demanding hole-drilling operations.”
Global Footprint & Upcoming Exhibitions
Drillstar’s BTA tools have gained international recognition, with exports to over 30 countries across Europe, Asia, and the Americas. The company will showcase its latest BTA innovations at EMO Hannover 2025 (Hall 3, Booth H17) and Moscow International Machine Tool Show 2025 (Booth 53A13), inviting global partners to explore cutting-edge deep hole solutions德州钻星刀具有限公司.
