Drilling, Tapping & Thread Repair

Precision Hole Machining and Thread Restoration for Heavy Engineering

Accurate holes and threads are critical to the performance of industrial machinery. Over time, wear, damage, or broken studs can compromise threads, misalign components, and lead to operational issues. Benroc Engineering provides expert drilling, tapping, and thread repair services on-site, restoring critical components to exact specifications and reducing costly downtime.

Whether it is clearance holes, dowel locations, or tapped holes, our in-house designed jigs and fixtures guarantee precision and repeatability across a wide range of applications.

Technical Overview & Benefits

Our drilling, tapping, and thread repair capabilities are designed to meet the demands of heavy engineering environments. Key features and benefits include:

• On-site precision machining – reduces equipment transport time and operational downtime.
• Thread repair and restoration – includes installation of threaded inserts for damaged holes.
• Broken stud and seized fastener removal – avoids component replacement and minimises disruption.
• Reaming and dowel hole machining – ensures accurate alignment of critical components.
• Trepanning and specialised hole machining – for large-diameter or deep holes where conventional tools cannot reach.

These techniques restore components to OEM tolerances, maintaining structural integrity and operational reliability.
