Regrinding & Refurbishment: The Smart Way to Extend Your Tool Life by Up to 80%
In precision engineering, tooling costs add up fast. Replacing worn drills, bore gauges, and cutting tools every time they lose their edge is expensive — and often unnecessary. That's where professional regrinding and refurbishment comes in.
At Hammond & Company, our reconditioning service restores your tooling to original performance specifications, extending usable life by up to 80% at a fraction of the replacement cost.
Why Regrind Instead of Replace?
Most cutting tools don't fail — they simply wear. The geometry dulls, coatings thin out, and tolerances drift. But the core tool body remains sound. Regrinding removes only the minimum material needed to restore sharp cutting edges and correct geometry, bringing the tool back into specification.
Throwing away a worn gun drill or bore gauge that still has life in it is like scrapping a car because the tyres are worn. It doesn't make economic or environmental sense.
What We Recondition
Our Hemel Hempstead facility handles regrinding for gun drills, Ventec drills, and Speedfeed drills. Each tool is inspected, reground to original geometry, and can be recoated with TiN or TiAlN to match or exceed original performance. Bore gauges can also be refurbished and recertified to BS 969, DIN 7164, or ANSI B89.1.5 standards.
The Benefits at a Glance
Regrinding typically costs 30–50% less than buying new, and turnaround is faster than waiting for a new tool to be manufactured. You also reduce waste and keep proven tooling in your production cycle rather than breaking in new tools. Recertification ensures your refurbished gauges remain fully traceable and audit-ready.
When Should You Regrind?
The best time is before a tool fails catastrophically. If you're noticing rougher surface finish, increased cutting forces, or bores drifting toward tolerance limits, it's time to send your tools in. Catching wear early means less material needs to be removed, which means more regrind cycles over the tool's lifetime.
Getting Started
Contact Hammond & Company to discuss your regrinding requirements. Whether it's a single gun drill or an entire fleet of bore gauges, our team will assess condition, provide a quote, and return your tooling ready for production.
