SUNNY Holds First Internal Training on Diamond Core Drill Bits
Last week our sales and technical support teams gathered for the first session of an internal product training program. The topic: diamond core drill bits — how they're made, how to match them to a job, and what to watch out for on site.
A customer asking about a diamond core drill bit rarely asks a simple question. They want to know whether a bit will handle rebar, whether it can run dry, what segment life to expect on their rig. Answering that properly takes more than a product catalogue — it takes people who understand what's happening inside the tool.
That was the reason for this program. We want every person who speaks with a customer to be able to give a real recommendation, not just a price quote.
The session worked through the full picture of engineering drill bit products:
- Product classification — how bits are grouped by application (stone drilling vs reinforced concrete drilling) and by manufacturing method
- Manufacturing processes — sintering, electroplating, laser welding, and silver brazing, and what each one is actually good for
- Working principle — why a diamond bit grinds rather than cuts, and how self-sharpening keeps a segment working through its whole life
- Segment teeth selection — flat, turbo/spiral, and U-shape patterns, and which jobs each one suits
- Safety standards — including the rule that a wet-rated silver-brazed bit must never be run dry, because heat can melt the brazing and send a segment flying
- Formula performance data — real test results across different bond formulas, diameters, and rig power ratings
The most useful part of the session wasn't any single specification — it was seeing how many variables sit behind one finished bit. Engineering drill bits are non-standard products: eight teeth patterns, eleven core configurations, six thread types, and working lengths from 50mm to 650mm, with different bond formulas for different concrete conditions.
There's no universal answer. Understanding a customer's material, rig, and working conditions is the only way to recommend something that actually performs — and that's exactly what this training was meant to build.
This was the first of an ongoing series. Upcoming sessions will cover other product lines, including diamond saw blades and floor grinding tools.
