The CC-GRIND FLEX is the semi-flexible addition to the CC-GRIND SOLID. It was developed especially for work on weld seams. Butt welds can be completely smoothed. This means bumps and dents – especially ones that are visible after coating or painting – are a thing of the past.

Semi-flexible grinding disc with precision-formed, angular high-performance VICTOGRAIN abrasive grain for steel with maximum grinding performance and outstanding tool life.

Grinding Discs FAQs

Answers on how depressed-centre grinding discs and bench grinder wheels are built, chosen, fitted and used on steel, stainless steel and aluminium.

Why do grinding discs have glass fibre layers inside?

Discs for heavy grinding are normally reinforced with resin-coated woven glass fibre mat. The reinforcement lets the disc withstand the high stresses of hand-held grinding and helps hold fragments together if a disc does break.

That is why only discs made for hand-held use, with the right bond and reinforcement, should go on an angle grinder. The reinforcement is not a reason to relax: the guard must always stay fitted, you must stay within the speed marked on the disc and the disc should be replaced if it is damaged. Do not try to use bench grinder wheels or other unsuitable wheels on a hand-held grinder.

Can I use a grinding disc on its edge to cut a slot or a bar?

No, not unless the disc is marked as suitable for both grinding and cutting. Grinding discs and cutting-off wheels are different types, made for different loads. A grinding disc is designed to work on its face, and loading it sideways in a cut risks cracking or breaking it.

If you need to cut, use a reinforced cutting-off wheel approved for hand-held machines. Look at the markings on the disc for restrictions, which can include not for face grinding or not for hand-held cutting, and obey them. If in doubt, read the maker's instructions.

What angle and pressure should I use for grinding?

Hold the disc at a modest angle to the work, as the disc maker's instructions describe, and use light, steady pressure so the disc does not grab or kick. Let the grinder reach full speed before it touches the metal, keep it moving and hold it with both hands.

Pushing hard does not speed things up much and risks overloading the disc, overheating the work and losing control. If a disc snags, switch off and let it stop fully before freeing it. Stay out of the line the grinder would travel if it kicked back.

Is a thicker grinding disc better than a thinner one?

Thickness is a trade-off. Thicker discs generally give longer life and suit heavy, aggressive work such as bevelling and weld removal. Thinner discs can be more manoeuvrable and suit lighter weld dressing, but they wear faster.

The disc must always suit the grinder: the diameter, bore and the maximum speed marked on the disc must match the guard and the speed on the grinder's data plate. Do not choose by thickness alone, and do not remove a guard to fit a bigger disc. Follow the manufacturer's recommendations for the metal and the task.
