Drilling & Holemaking Services — Code 1903.1.0018 | Vinahardware

Overview
Vinahardware’s Drilling & Holemaking process (Code 1903.1.0018) delivers precision holemaking across a wide spectrum of parts and materials. Our capabilities range from manual and radial drilling to CNC drilling centers, multi-spindle production drilling and specialized gun-drill operations for deep holes. We provide secondary operations including reaming, tapping, countersinking, boring and deburring, offering turnkey holemaking solutions for prototypes and volume production.

Equipment & Capabilities

• Manual & radial drill presses for large fixtures and low-volume parts.

• CNC drilling centers and machining centers with peck drilling, through-coolant and automatic tool changers.

• Multi-spindle drilling machines for high-volume repeatable hole patterns.

• Gun-drill and deep-hole drilling units for high length-to-diameter ratios.

• Tapping heads, reamers, countersink tooling and deburring stations. Jigs & fixtures are built in-house for precision positioning.

Materials & Ranges

• Metals: carbon steel, alloy steels, stainless steels (SUS304/316), aluminum, brass, cast iron.

• Plastics & composites: POM, ABS, technical plastics.

• Hole diameters from ~0.5 mm up to 60+ mm and deep holes up to several hundred millimeters (depending on tool & machine).

Quality & Control

• Positional tolerances typically achievable: ±0.05 mm to ±0.2 mm depending on part & fixturing.

• In-process inspection with plug gauges, bore gauges and CMM reporting for critical features.

• Batch QC documentation and photo records available for export compliance.

Workflow

1. Customer submits drawings (2D/3D) and holelist.

2. Vinahardware proposes drilling strategy, tooling and fixturing.

3. Sample run and customer approval.

4. Production with scheduled in-process inspections.

5. Reaming/tapping/finishing and final QC. Packaging for shipment.

Applications

• Furniture assemblies, machine components, electronic enclosures, automotive brackets, medical device fixtures and structural assemblies.
