5 Signs Your Drilling Tools Need Refurbishment or Hardfacing

Drilling tools are the backbone of every oilfield operation, enduring extreme conditions – heat, pressure, abrasion, and mechanical stress. Even the most durable tools eventually experience wear that can affect performance, efficiency, and safety. Recognizing early signs of wear allows operators to refurbish or apply hardfacing before minor damage becomes a costly failure.

At JOT Oilfield Services, our expertise in tool refurbishment and hardfacing ensures drilling tools remain reliable and ready for every challenge. Here are five clear signs it’s time to service your drilling tools.

1. Visible Wear or on Tool Surface

One of the first and most obvious signs that your tool needs refurbishment is surface wear, pitting, or erosion. Constant contact with rock formations and abrasive fluids gradually strips away protective coatings and weakens the tool’s surface.

Ignoring this wear can lead to:

  • Reduced cutting efficiency
  • Weakened structural integrity
  • Sudden tool failure during operations

Hardfacing restores these surfaces with wear-resistant materials like tungsten carbide, extending the tool’s lifespan and maintaining performance.

2. Loss of Cutting Edge Sharpness

Milling and drilling tools rely on sharp, uniform edges to maintain efficiency. If you notice decreased drilling speed or rougher cut surfaces, it’s a sign your tool edges have dulled over time.

Why this matters:

  • Dull tools increase torque and stress on equipment
  • They consume more power and slow down drilling progress
  • Cutter damage can quickly escalate if not reconditioned

Applying hardfacing with precision edge rebuilding can rejuvenate these cutting surfaces, restoring performance close to brand-new condition.

3. Irregular Tool Geometry or Shape Deformation

Drilling creates significant mechanical pressure on downhole tools. Over multiple runs, tools may lose shape, bend slightly, or develop geometry irregularities that affect directional control and cutting uniformity.

These deformations usually occur in stabilizers, drill collars, reamers, or window mills. Refurbishment involves precision CNC re-machining and balancing to restore the original specifications, ensuring smooth, accurate drilling.

4. Frequent Tool Failures or Shorter Run Life

If your tools are no longer lasting the expected number of runs, it’s a strong indicator that material fatigue or abrasive damage has set in. Continually replacing tools instead of refurbishing them increases operational costs significantly.

Timely refurbishment helps:

  • Restore structural performance
  • Extend tool run life
  • Reduce overall maintenance and replacement costs

5. Increased Vibration or Operational Noise

Unusual vibration or noise during drilling usually signals imbalance, uneven wear, or inadequate surface protection. Over time, this can cause equipment misalignment and safety hazards.

Solution:
Through precision reconditioning and hardfacing, JOT restores tool balance, surface uniformity, and durability – minimizing vibration and ensuring safe, smooth operation.
