BTA Deep Hole Drilling Tools – Precision & Efficiency
Professional-grade BTA (Boring & Trepanning Association) drills engineered for high-performance deep hole machining in metals. Features advanced coolant-through design for optimal chip evacuation and heat reduction, ensuring straight, accurate holes (up to 250xD depth) with superior surface finish.
Faedah Utama:
✔ Internal Coolant System – Directs high-pressure coolant to cutting edges
✔ Guided Cutting Action – Maintains hole straightness in deep applications
✔ Modular Design – Replaceable tips reduce tooling costs
✔ Material Versatility – Effective on steel, alloys, and tough metals
Ideal for oil/gas, aerospace, and mold manufacturing. (Available in carbide & HSS versions)
Product Description
BTA drill, also known as internal chip removal deep hole drill, has the following product advantages:
high-precision
-High aperture accuracy: BTA drill can accurately control the diameter size of the borehole with a small tolerance range, achieving H7 level or even higher accuracy, meeting the machining requirements of high-precision holes in industries such as aerospace and automotive manufacturing
-Good straightness of the hole: During the drilling process, the BTA drill bit and guide device can effectively ensure the straightness of the hole, prevent the hole wall from bending or tilting, ensure the quality and accuracy of deep hole machining, and make the drilled hole fit more tightly and accurately with other components
high efficiency
-High speed drilling capability: BTA drill can achieve high cutting speeds and feed rates, significantly reducing the processing time of individual holes and improving production efficiency, especially suitable for mass production processing
-Simultaneous processing of multiple holes: With corresponding fixtures and tool systems, BTA drill can process multiple holes simultaneously in one clamping, further improving processing efficiency and reducing the time required for processing procedures and equipment
High durability
-Small tool wear: The tools used in BTA drill are usually made of special hard alloy materials or undergo special surface treatment, which have higher hardness and wear resistance, can withstand high temperature and high pressure during high-speed cutting and deep hole machining, reduce tool wear, extend tool life, and reduce tool replacement frequency and cost
-Strong equipment stability: The BTA drill machine tool has a sturdy structure and high manufacturing accuracy for each component, which can maintain stable performance during long-term high-intensity processing, reduce production interruptions caused by equipment failures, and provide reliable guarantees for the continuous production of enterprises
