Diamond Segment for Core Drill Bit

The segment's geometry directly impacts drilling speed, entry quality, and the final finish. Here is a quick guide for matching segment shapes to applications:

• Roof/Turbo: For fast, clean entry for concrete diamond coring.
• Straight Groove/Arix: For balanced cooling and force distribution for RC wet coring.
• M-pit: For efficient chip evacuation in abrasive masonry.
• Groove Dot: For large chip space for asphalt coring.
• Crown/Dot Tip: For precise, low-chipping holes for small-diameter porcelain/ceramic coring.

Always verify the core bit's interface (threads/adaptors) for compatibility with your rig and check for CE compliance. It's good practice to perform a test on an off-cut piece before starting production drilling.

Diamond coring speed vs segment life: optimizing performance requires balancing the penetration rate (speed) with the segment's wear rate (life). The key is in the formulation:

• Bonds: Softer bonds wear faster to expose new diamonds, ideal for hard, non-abrasive materials. Harder bonds resist wear, suitable for abrasive materials like masonry.
• Grit: Finer diamond grit is used for brittle materials like ceramics to minimize chipping. Coarser grit allows for faster cuts in materials like concrete.

A typical segment height is 8–12 mm, providing substantial operational life. Monitor for glazing (a sign the bond is too hard) and dress the segment to re-expose diamonds. Track the number of holes drilled per segment to manage your Total Cost of Ownership (TCO) and schedule timely re-tipping based on your target RPM/line speed.

Ensuring core drill rig compatibility, including the connection thread and diameter range, is crucial for safety and performance.

Customization supported—no compatibility worries; standard coring head diameters: Ø25–356 mm.After re-tipping, it's important to check for proper balance and minimal runout.

Before ordering, confirm CE labelling and any specified torque settings for the connection. Share your target RPM and line speed with your supplier to ensure the segment bond is correctly matched.

• Diamond segment specs: Segment height and other specs are defined by product series; customization available on request.
• Lead Time: Typically 7–15 days; in‑stock items ship immediately (confirm before order).
• Minimum Order Quantity (MOQ): Generally 10 pieces; varies by specification.

Recognizing wear signs and acting promptly is key to maintaining cutting efficiency and avoiding damage. Look for these two common signs:

• Glazing:If the segment surface becomes smooth and shiny, it needs to be "dressed" or resharpened to expose new diamonds.
• Loss of Speed:A significant drop in cutting speed indicates the segments are worn out and it's time to re-tip the core bit.

Establish scheduled dressing cycles based on your application. Keep spare segments on hand to minimize downtime. Log maintenance actions and track the number of holes drilled to help with future planning.

Setting the correct rotational speed (RPM) is vital for safety, efficiency, and tool life. Recommended RPM varies by diameter. Use these ranges as a starting guide:

• Small Diameter (e.g., <50mm):1000–2500 RPM
• Medium Diameter (e.g., 50-150mm):500–1200 RPM
• Large Diameter (e.g., >150mm):300–700 RPM

For reinforced concrete, always prefer wet coring and monitor the temperature and slurry.

Always start at a lower RPM and gradually increase to the optimal speed, avoiding chatter and vibration. Ensure your RPM setting aligns with the recommended surface speed (line speed) for the material.
