Precision Deep Hole Drilling Services
We specialise in accurate deep hole drilling in steel and other metals.
Gun Drilling & BTA
Deep hole drilling on steel blocks, bases and cores using gun drilling and BTA.
Flexible Production
Single prototypes, repair parts and repeat batch orders.
Drawing-Based
Holes drilled strictly according to your 2D/3D drawings.
Proceso de Personalización
Desde la materia prima hasta el producto terminado — paso a paso con precisión.
Consulta de Proyecto y Planos
01
Indíquenos si necesita bloques de acero para moldes pre-mecanizados o piezas de molde terminadas, y envíenos el grado del material, las dimensiones y los planos 2D/3D.
Revisión Técnica y Cotización
02
We check feasibility, select the drilling method and send a quotation with lead time.
Confirmación de Pedido
03
Usted confirma las cantidades, especificaciones y condiciones de entrega; nosotros emitimos la Factura Proforma (PI) y programamos la producción.
Corte a Medida
04
Cut steel to size if needed, mark hole positions and set up fixtures and supports.
Taladrado de agujeros profundos
05
Gun drilling / deep hole drilling on dedicated machines, with in-process checks.
Inspection & Documentation
06
Critical dimensions are checked. Inspection reports and material certificates can be issued if requested.
Embalaje y Envío
07
Se organizan la protección antioxidante, el embalaje en cajas y los documentos de exportación; el envío se realiza por aire, tierra o mar con seguimiento.

Coordinate Measuring Machine (CMM)
Precision 3D dimensional inspection, accuracy up to 0.001 mm.
Bore Gauge (Hole Diameter Gauge)
High-accuracy bore measurement with automatic data logging.
Straightness Tester
Deep-hole straightness inspection to ensure bore perpendicularity.
Surface Roughness Tester (Profilometer)
Checks bore surface finish to ensure the Ra value meets spec.
What materials can you drill?
+
Carbon/alloy steels, mold steels, stainless steel, aluminum alloys, copper/brass, and some engineering plastics (e.g., acrylic). Contact us for special materials.
What hole sizes and depths can you handle?
+
Typical capacity Ø4–60 mm; depths up to ~1,500 mm (method-dependent).
What accuracy can you achieve?
+
φ2–32 mm ±0.02 mm; φ35–120 mm ±0.05 mm; straightness ≤0.01 mm per meter; surface finish Ra 0.2–0.6 μm.
How fast can you deliver rush jobs?
+
With 24/7 capacity, some urgent parts can ship within 24 hours depending on specs and quantity. Standard orders: 3–7 working days.
Do you support customer-supplied material or turnkey?
+
Both. Send your material or let us source steel/aluminum locally; bulk purchasing can reduce total cost.
What do you need for a quote?
+
2D/3D drawings with hole diameter, depth, tolerance, position, quantity, material, and any heat-treat/finish requirements (STEP/IGES/DWG accepted).
Do you provide inspection reports?
+
Yes. Diameter, straightness, and surface roughness reports available. CMM and dedicated gauges are calibrated with traceable records.
What processes do you use?
+
Gun drilling and BTA; we choose based on diameter, depth, and chip evacuation to ensure stable quality and efficiency.
