Import Bta Drill Head — Buy in wholesale FOB from Supplier in South Korea (Republic Of Korea)

The BTA Drill Head from E-Tech Inc is a deep-hole drilling tool manufactured in Seoul, South Korea, offered in both brazed and indexable insert constructions. BTA (Boring and Trepanning Association) tooling operates on a single-tube system where coolant is supplied through the tool head and chips evacuated through the drill tube centre, distinguishing it from gun drilling and ejector systems. The listing highlights precision engineering, high-grade steel construction, and integrated coolant channels as core features, with options spanning multiple diameters and lengths for metalworking applications.

Brazed type heads use permanently bonded carbide cutting edges, typically yielding higher rigidity and finer surface finishes in continuous production of hydraulic cylinders and crankshaft bores. Indexable insert types accept replaceable carbide or cermet inserts, reducing per-hole tooling cost and allowing indexed cutting edge renewal without removing the head from the machine. Standard BTA diameters range from approximately 15 mm to over 200 mm, with length-to-diameter ratios from 100:1 to 400:1 achievable depending on machine stability and chip evacuation efficiency. The high-grade steel substrate referenced in the listing typically refers to alloy steels such as 42CrMo4 or similar, heat-treated to 48-52 HRC for fatigue resistance under cyclic cutting loads.

Primary buyers include manufacturers of hydraulic cylinders, oil field equipment, defence barrels, and large diesel engine blocks in automotive, aerospace, and heavy machinery sectors. The enhanced cooling system described is critical for BTA performance, as coolant pressure of 20-70 bar is typical for effective chip breaking and evacuation. Importers should confirm available diameter ranges, insert seat geometry (for indexable types), maximum recommended cutting parameters, and whether E-Tech Inc provides application engineering support for tool setup and parameter optimisation. South Korean cutting tool manufacturers often specialise in hardened steel and difficult-to-machine alloy applications, so buyers should inquire about specific material group recommendations and tool life benchmarks.

E-Tech Inc is headquartered in Yeongdeungpo-Dong, Yeongdeungpo-Gu, Seoul, 150038, South Korea. The company holds a harbor trust tier on the platform. The response rate is recorded as 0.00% with zero average response hours, indicating either a new listing, limited platform engagement, or incomplete data population rather than necessarily reflecting business inactivity.

No establishment year, employee count, annual revenue, factory details, or named clients are provided in the source data. Seoul's Yeongdeungpo district is a major commercial and light industrial hub, though significant cutting tool manufacturing in South Korea is often concentrated in Gyeonggi Province or Incheon. Buyers should verify whether E-Tech Inc operates its own manufacturing facility or functions as a trading company, and request facility audit reports or manufacturing capability documentation before large commitments.
